I don't see anything on the desktop. the output of "dmesg | tail -n10" gives me: [ 1965.696388] hub 1-0:1.0: unable to enumerate USB device on port 1 [ 1965.884537] hub 1-0:1.0: unable to enumerate USB device on port 1 [ 1966.072503] hub 1-0:1.0: unable to enumerate USB device on port 1 [ 1966.260349] hub 1-0:1.0: unable to enumerate USB device on port 1 [ 1966.506227] usb 1-1: new high speed USB device using ehci_hcd and address 9 [ 1966.572375] hub 1-0:1.0: unable to enumerate USB device on port 1 [ 1966.760379] hub 1-0:1.0: unable to enumerate USB device on port 1 [ 1966.948358] hub 1-0:1.0: unable to enumerate USB device on port 1 [ 1967.136335] hub 1-0:1.0: unable to enumerate USB device on port 1 [ 1967.325423] hub 1-0:1.0: unable to enumerate USB device on port 1 When connecting my usb scanner to the same port: [ 2008.480135] usb 1-1: new high speed USB device using ehci_hcd and address 65 [ 2008.548389] hub 1-0:1.0: unable to enumerate USB device on port 1 [ 2008.736786] hub 1-0:1.0: unable to enumerate USB device on port 1 [ 2008.924379] hub 1-0:1.0: unable to enumerate USB device on port 1 [ 2009.112348] hub 1-0:1.0: unable to enumerate USB device on port 1 [ 2009.300443] hub 1-0:1.0: unable to enumerate USB device on port 1 [ 2009.488536] hub 1-0:1.0: unable to enumerate USB device on port 1 [ 2009.732180] usb 1-1: new high speed USB device using ehci_hcd and address 71 [ 2014.796299] hub 1-0:1.0: unable to enumerate USB device on port 1 [ 2018.000128] usb 2-1: new full speed USB device using uhci_hcd and address 3 And ubuntu 10.10 recognizes that scanner. So: What can i do to see my usb stick? BTW: on my other Thinkpad running fedora 14 it works perfectly... Cheers -Peter

• Create Device Reccieve SMS Parse To Text ( SMS Gateway )

  - by Chris Okyen

  I want to use a server as a device to run a script to parse a SMS text in the following way. I. The person types in a specific and special cell phone number (Similar to Facebook’s 32556 number used to post on your wall) II. The user types a text message. III. The user sends the text message. IV. The message is sent to some kind of Device (the server) or SMS Gateway and receives it. V. The thing described above that the message is sent to then parse the test message. I understand that these three question will mix Programming and Server Stuff and could reside here or at DBA.SE How would I make such a cell phone number (described in step I) that would be sent to the Device? How do I create the device that then would receive it? Finally, how do I Parse the text message?

• How to disable hiddev96 in linux (or tell it to ignore a specific device)

  - by Miky D

  I'm having problems with a CentOS 5.0 system when using a certain USB device. The problem is that the device advertises itself as a HID device and linux is happy to try to provide support for it: In /ver/log/messages I see a line that reads: hiddev96: USB HID 1.11 Device [KXX USB PRO] on usb-0000:00:1d.0-1 My question comes down to: Is there a way to tell linux to not use hiddev96 for that device in particular? If yes, how? If not, what are my options - can I turn hiddev96 off completely? UPDATE I should probably have been a bit more specific about what is going on. The machine is running Centos 5.0, and on top of it I'm running VMWare workstation with Windows XP - which is where the USB device is actually supposed to operate. All works fine for other USB devices (i.e. VMWare successfully connects the USB device to the guest OS and the OS can use it, but for this particular device VMWare connects it to the guest OS, but the OS can't read/write to it) Every attempt locks up the application that is trying to communicate with the device. I've reason to believe that it is because the device is a HID device and there's some contention between the Linux host and the Windows guest OS in accessing the device. Below is the output from modprobe -l|grep -i hid as requested by @Karolis: # modprobe -l | grep -i hid /lib/modules/2.6.18-53.1.14.el5/kernel/net/bluetooth/hidp/hidp.ko /lib/modules/2.6.18-53.1.14.el5/kernel/drivers/usb/misc/phidgetservo.ko /lib/modules/2.6.18-53.1.14.el5/kernel/drivers/usb/misc/phidgetkit.ko And here is the output of lsmod # lsmod Module Size Used by udf 76997 1 vboxdrv 65696 0 autofs4 24517 2 hidp 23105 2 rfcomm 42457 0 l2cap 29633 10 hidp,rfcomm tun 14657 0 vmnet 49980 16 vmblock 20512 3 vmmon 945236 0 sunrpc 144253 1 cpufreq_ondemand 10573 1 video 19269 0 sbs 18533 0 backlight 10049 0 i2c_ec 9025 1 sbs button 10705 0 battery 13637 0 asus_acpi 19289 0 ac 9157 0 ipv6 251393 27 lp 15849 0 snd_hda_intel 24025 2 snd_hda_codec 202689 1 snd_hda_intel snd_seq_dummy 7877 0 snd_seq_oss 32577 0 nvidia 7824032 31 snd_seq_midi_event 11073 1 snd_seq_oss snd_seq 49713 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event snd_seq_device 11725 3 snd_seq_dummy,snd_seq_oss,snd_seq snd_pcm_oss 42945 0 snd_mixer_oss 19009 1 snd_pcm_oss snd_pcm 72133 3 snd_hda_intel,snd_hda_codec,snd_pcm_oss joydev 13313 0 sg 36061 0 parport_pc 29157 1 snd_timer 24645 2 snd_seq,snd_pcm snd 52421 13 snd_hda_intel,snd_hda_codec,snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer ndiswrapper 170384 0 parport 37513 2 lp,parport_pc hci_usb 20317 2 ide_cd 40033 1 tg3 104389 0 i2c_i801 11469 0 bluetooth 53925 8 hidp,rfcomm,l2cap,hci_usb soundcore 11553 1 snd cdrom 36705 1 ide_cd serio_raw 10693 0 snd_page_alloc 14281 2 snd_hda_intel,snd_pcm i2c_core 23745 3 i2c_ec,nvidia,i2c_i801 pcspkr 7105 0 dm_snapshot 20709 0 dm_zero 6209 0 dm_mirror 28741 0 dm_mod 58201 8 dm_snapshot,dm_zero,dm_mirror ahci 23621 4 libata 115833 1 ahci sd_mod 24897 5 scsi_mod 132685 3 sg,libata,sd_mod ext3 123337 3 jbd 56553 1 ext3 ehci_hcd 32973 0 ohci_hcd 23261 0 uhci_hcd 25421 0

• Files backup utility with incremental backups that would keep backup device clean

  - by Wojtek

  I've tested a few of backup utilities and still haven't found one that would satisfy me. Almost every one of them has two options: - full backup - not an option to use frequently - incremental backup - seems right, but there's one thing about it: Incremental backup builds on a base of a full backup, backing up only those files, that were created/changed. The thing is, that after some time you've got a lot of unwanted files from the old backups bloating your backup device. Also, if you'd accidentally delete your full (first) backup file, then the differential backups would be corrupted (you wouldn't be able to restore them). The thing I'm looking for is a program, that would backup files simply by copying them. It would check the backup device whether it contains the file (unchanged): - if yes, it should proceed to the next file (we've got current version backed up) - if no, it would copy the file to the backup device - if the device contains a file that is no longer on our disk, the program would delete it from the backup device Is there any such utility, that would work this way? If not, do you have any hints on how to backup fairly big amounts of data (around 20gb) quite frequently with incremental backups and not be exposed to those unwanted effects of backup size puffing up?

• `power/persist` file not found in USB device sysfs directory

  - by intuited

  The file /usr/share/doc/linux-doc/usb/persist.txt.gz mentions that the USB-persist capability can be enabled for a given USB device by writing 1 to the file persist in that device's directory in /sys/bus/usb/devices/$device/power. This is said — if I understood correctly — to allow mountings of volumes on the drive to persist across power loss during suspend. However, I've discovered that the device I'd like to enable this facility for — a USB hard drive — does not have such a file in its corresponding directory, and that attempts to create it are rebuffed. Is there perhaps a kernel module that needs to be loaded for this to work? Do I need to build a custom kernel? I'm running ubuntu 10.10.

• ALSA samples capture: cannot open device

  - by Randagio

  I'm quite new to Linux (Lubuntu 12.04 for sake of precision) and ALSA programming at all. I'm trying to write a C program to capture audio from internal PC microphone for processing it. So as first step I google a bit and I found this article for capturing audio samples A tutorial on using the ALSA Audio API but when I compile it and execute it with: ./capture "default" or ./capture "hw:0,0" and all the possible variants on theme it always raises the error: cannot open device hw:0,0 (no such file or directory). So the issue is: what is the name of the mic audio device to pass as parameter to record the audio from mic ? The mic is working ok because the Sound Recorder program records sounds perfectly and I can playback them. The output of the aplay -l is the following : **** List of PLAYBACK Hardware Devices **** card 0: I82801DBICH4 [Intel 82801DB-ICH4], device 0: Intel ICH [Intel 82801DB-ICH4] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: I82801DBICH4 [Intel 82801DB-ICH4], device 4: Intel ICH - IEC958 [Intel 82801DB-ICH4 - IEC958] Subdevices: 1/1 Subdevice #0: subdevice #0 and this is the amixer output (cut) Simple mixer control 'Master',0 Capabilities: pvolume pswitch penum Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 31 [100%] [0.00dB] [on] Front Right: Playback 31 [100%] [0.00dB] [on] Simple mixer control 'Master Mono',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined penum Playback channels: Mono Limits: Playback 0 - 31 Mono: Playback 4 [13%] [-40.50dB] [on] Simple mixer control 'PCM',0 Capabilities: pvolume pswitch penum Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 31 [100%] [12.00dB] [on] Front Right: Playback 31 [100%] [12.00dB] [on] Simple mixer control 'CD',0 Capabilities: pvolume pswitch cswitch cswitch-exclusive penum Capture exclusive group: 0 Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: Playback 0 - 31 Front Left: Playback 0 [0%] [-34.50dB] [off] Capture [off] Front Right: Playback 0 [0%] [-34.50dB] [off] Capture [off] Simple mixer control 'Mic',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined cswitch cswitch-exclusive penum Capture exclusive group: 0 Playback channels: Mono Capture channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Playback 22 [71%] [-1.50dB] [on] Front Left: Capture [on] Front Right: Capture [on] Simple mixer control 'Mic Boost (+20dB)',0 Capabilities: pswitch pswitch-joined penum Playback channels: Mono Mono: Playback [off] Simple mixer control 'Mic Select',0 Capabilities: enum Items: 'Mic1' 'Mic2' Item0: 'Mic1' Simple mixer control 'Stereo Mic',0 Capabilities: pswitch pswitch-joined penum Playback channels: Mono Mono: Playback [off] so for aplay it seems I have no recording device, but for amixer I've got the mic, a mic boost and mic stereo as well with all those gorgeous stuffs on their place !!. If so, how could my Sound Recorder record the audio without any problem at all ?!?! For sure I'm giving the wrong device name to the command line for capturing audio but I'm loosing the hope for finding the correct one ! Please help....before I tear my hair out !!!

• Force usb to use same device id, instead of new one

  - by m s kumar

  I am having some trouble in automating the task. I am testing some android based mobiles in linux machine. The automation script uses the device id under "/dev/bus/usb/001/"053" it will be always under bus 001 only.. But the dev is will be random like if i insert one mobile then the dev id will be 053, if remove and insert it again then the dev id will be 054.. The problem is, when some tests runs on the device and if device gets rebooted then new dev id is showing for the rebooted one and my scripts failing due to new dev id.. Is there any way to force usb devices to use same dev id instead of new one. So that there will be no issues to my tests even after device reboots. Thanks in advance.

• manage 2 wireless device

  - by yi.tang.uni

  I erased Windows 7 and installed Ubuntu 12.04 on my Dell Latitude E4200. I an very happy with my choice but with little pity. I cannot use the wireless service in my university as the build-in device works unstable. I bought a USB wireless device, which solve the problem. However, the build-in device keep to sent me message about unable to connect, which waste laptop's cup & battery. The phsical bottom to turn off wireless affect both devices. So the question is: "How can I manually shut down wireless device?" There is another interest comes to my mind: "Does 2 wireless improve the overall internet usage if I run a high-internet-consuming program like BT ?" Thank for your time and energy.

• error: no device connected

  - by Prabath Swarna

  I did a fresh install of 12.04 and it went fine, worked on it for several days, but one day the browser crashed and i reset the machine, after that I get this error when i boot; error: no device connected error: no device connected error: no device connected error: no device connected This comes after the BIOS confirmation, and it stays for about 30 seconds, then the grub menu comes and when I selected the default the screen becomes purple and stays like that for a whole Minuit. I thought maybe that is because I have 500GB HDD so i ran the boot-repair, It did nothing at all. I'm sure I did the boot-repair thing right, sorry I forgot the paste URL. If i reinstalled will this error persist.

  I have a very old graphic card that only supports shader model 2, but I need shader model 3 or up for the app I am developing. I tried to use a reference device but it seems to run very slowly, then I found some samples in C++ that allows me to change to a WARP device and the performance is good. I am using C# and I don't know how to create such type of device. So the question is: how do I create a WARP device in C#? Thanks in advance.

• Sony VGN-NR260E "External Device Boot"

  - by user72158

  [A LITTLE BACKGROUND] On all modern Dell computers pushing the F12 on bios boot will allow for a screen that lets you choose what boot option you need. For example if I want to boot off of a USB flash drive to boot into a live Linux distribution in order to clean virus's on netbooks that do not have CD drives to boot from I would push F12 and choose USB device from the list of options. If this does not show up then I can always go to the F2 bios setup and choose flash drive to be the first option. When I restart the computer it will boot into the flash device. I understand that I can purchase an external USB CD drive and then boot from that. I do not want to use that option. The reason for using a flash device instead of a CD is: A: This USB flash device has several different boot OS's on it that are used. B: The antivirus disks are updated often and burning cd's and throwing away others is wasteful compared to simply updating a flash drive. There is nothing wrong with the flash drive. It works perfect on many other PC's. [PROBLEM] Booting this flashdrive has been working for years on hundreds of computers... I just have this ONE computer that I cannot figure out how to get it to boot on... I have a Sony Vaio that will not boot to this device. I've tried pushing every key combo I can think of (F12, Esc, Del, F10...) and none of these key combinations will bring up the boot menu. I chose F2 and went into the bios and changed the first boot device to USB flash device. This did not work either. There is an astrix next to the device and the note states: "This Drive is available when External Device Boot is Enable." [WHAT I NEED] I need to know How to enable External Device Boot on the Sony Vaio VGN-NR260E laptop. OR How to bring up the Boot Menu to allow me to boot off a flash device. Thanks for anyone that can help!

• How to implement/debug a sensor driver in ANDROID

  - by CVS-2600Hertz-wordpress-com

  Does anyone know of a walk-through or any examples of any code to setup sensors in android. I have the drivers available to me. Also i have implemented the sensors library as instructed in the Android-Reference along the sensors.h template. I am still unable to get any response at the apps level. How do i trace this issue? what might be the problem? Thanks in advance UPDATE: Jorgesys's link below points to a great APP to test if the sensor drivers are functioning properly or not. Not that i know they are not functioning, Any ideas of on where to dig??...

• Can I prevent an IDENTIFY PACKET DEVICE command to a specific device at boot?

  - by Brian Spisak

  This is related to a previous question related to installation that is now resolved. I'm opening a new question, because I still need to get my DVD drive working. Problem: Failed boot when my ASUS DRW-24B1/ST DVD drive is attached to my asmedia ASM1061. Symptom: ata8.00: exception Emask 0x52 Sact 0x0 SErr 0xffffffff action 0xe frozen ata8: SError: { blah blah } ata8.00: failed command: IDENTIFY PACKET DEVICE ata8.00: cmd blah blah res blah blah (ATA bus error) ata8.00: status: { DRDY } ata8: hard resetting link Background: The ASM1061 is a PCIe to SATA bridge providing 2 x 6Gb/s ports and is supposed to be fully compliant to SATA specs. I just discovered in the fine print of my ASUS P8Z77-V pro motherboard that "These SATA ports are for data hard drivers only. ATAPI devices are not supported." However, I have already installed Windows 7 using this drive and I can run the Ubuntu 12.04 installer from it as well. The only time I have a problem is during Ubuntu boot when it tries an IDENTIFY PACKET DEVICE which seems to be an ATAPI command. I can't simply switch this device to another SATA port because they are already allocated to other devices. (My chipset's 2 x 6Gb/s are connected to my boot SSD and a fast HDD while the 4 x 3Gb/s ports are running a RAID 5 array.) If this can't be fixed or worked around, I suppose I'll have to go buy SATA add-in card. Blech. Thoughts: If indeed this is a device specific issue (that it doesn't support ATAPI discovery) then I can't expect - is it udev? - to work with it. But, it seems that Windows and even the Ubuntu installer work just fine. So why does udev have a problem? At the end of the day, it would be nice to have the DVD working under Ubuntu, but I can live without it. But, as this is a dual-boot machine, I can't physically disconnect it because I want it to work with Windows. (And physically disconnecting it every time I want to boot Ubuntu is NOT an option. ;-) Questions: Should this be considered a bug? My feelings are that if it works with other OS that it should probably work with Ubuntu as well. How can I work around this problem? I have a limited knowledge of linux internals, but it seems I should be able to somehow tell udev (or whatever is doing the discovery) to ignore that device. Is there a way?

• How does USB device recognition work?

  - by GorillaSandwich

  I'm curious how USB device recognition works in Windows. I imagine it's something like this: When you plug in a device, it tells Windows "here's my device ID to tell you what I am" Windows looks to see if any drivers have been installed that match that device ID. The driver probably tells Windows what the device should be called - like "BlackBerry Curve" or "Canon Printer" If so, it somehow associates that device with that driver Otherwise, it looks for a matching driver online (if you let it) Am I right? If so, that still leaves some questions. When you install drivers, where do they go? Are they files in a folder, or do they get added to the registry? What is Windows doing when it first recognizes the device, thinks, and finally says "your new device is installed and ready to use?" Where does Windows look for missing drivers? Is it in their own database? Do device manufacturers submit drivers to Microsoft for inclusion there? Can anybody explain how this process really works? Also, do other OSes do this differently?

• Intel Network Connection: This device cannot start. (Code 10)

  - by harryuser

  Hi, I have a Intel® Desktop Board DP55KG (see http://www.intel.com/products/desktop/motherboards/DP55KG/DP55KG-overview.htm), which has a Intel 82578DC Gigabit Network Connection on board. Additionally, I have a Intel PRO/1000 PT Dual Port Server Adapter in a PCI express slot and I am running Windows 7 Professional 32-bit. The problem I am having is that the Intel 82578DC Gigabit Network Connection will not start on boot with the following message: "This device cannot start. (Code 10)". Disabling and then enabling the device after boot makes the network connection work again without any problems, but as soon as I reboot the problem occurs again. Any suggestion how to fix this? I have seen this problem on another Intel S3420GP board as well in Windows 7 that is.

• USB Device With Embedded Fileserver

  - by Richard Martinez

  I'm attempting to access logs from a proprietary hardware box with no reasonable hope of modifying the software. There is a process on the device to dump log files to a flash drive on the USB port after entering a code sequence. Currently, analysis of the logs requires the following: Physical presence at the device Manual entry of the code sequence Removal of USB device Insertion of USB device into a normal Linux box I'm hoping there is some sort of device that can act as a USB mass storage device but simultaneously make it's contents available as a network file share (wired preferred). Does such a device currently exist? A combo hardware/software solution would also work.
