  • USB-to-Parallel adapter rated as USB 1.1 - will its driver lower speed of USB 2.0 bus?

    - by cumminjm
    I need to connect a printer with a parallel port to a computer with only a USB 2.0 bus. I'd like to do so without lowering the USB 2.0 bus speed to USB 1.1. All the USB-to-Parallel adapter cable found so far seem to be rated as USB 1.1 and they come with a CD which presumably contains a necessary driver. I haven't purchased one and tested it out yet, but if so, would the cable's driver lower speed of USB 2.0 bus?

  • Laptop Hard Drive Cable

    - by Josh Pennington
    I am about to have to dig into my wifes laptop to pull the hard drive out to pull the data off since the rest of it is close to dieing. I am curious what I should expect to have to deal with to get data off the hard drive. I am assuming its a SATA drive. Do I need a special cable to connect a laptop SATA hard drive to the computer or should I be able to connect it to my desktop computer without issue? Thanks Josh Pennington

  • Sending ASCII characters on Mac USB/RS232 cable

    - by Olivier
    Hello, I have a RS232C/USB cable to connect an electronic device to my iMac Intel (MacOSX SnowLeo 10.6.3). Is there a utility program that allows for sending ASCII characters on the USB port that the RS232C device will understand? If possible, I'd rather avoid programming. I'd prefer an Automator script or a simple program with a GUI. Thanks

  • Gsm modem submission rate

    - by myotherme
    Has anyone measured the rate of submission through a GSM modem? We are implementing a solution at the moment and are only able to submit at a rate of about one message every 3 to 5 seconds. We are not sure if this is a library/api problem or if our modem is just of poor quality. Has anyone had any experience with these devices and measured the throughput rate?

  • Shutdown Hangs for 5 Minutes on Kubuntu 14.04

    - by Augustinus
    I've had persistent problems with a 5 minute hang at shutdown for the last three versions of Kubuntu (13.04, 13.10, and now 14.04). I suspect this is not a KDE-specific problem. Recently, I performed a fresh installation of Kubuntu 14.04 from a live-USB, and shutdown worked normally for about a week. The hang-up is now happening again, and I can't figure out why. A brief description of the problem: The hang-up occurs with all methods of initiating a normal shutdown: Clicking the shutdown or restart button in KDE, sudo shutdown -h now, sudo reboot The shutdown splash screen appears. Using the down-arrow to access verbose messages, I see "Asking all remaining processes to terminate." This message remains for 5 minutes with no disk activity. Finally, a rapid series of messages flurries to the screen: * All processes ended within 300 seconds... [ OK ] nm-dispatcher.action: Caught signal 15, shutting down... ModemManager[852]: <warn> Could not acquire the 'org.freedesktop.ModemManager1' service name ModemManager[852]: <info> ModemManager is shut down * Deactivating swap... [ OK ] * Unmounting local filesystems... [ OK ] * Will now restart` Possible Sources of the Problem: Before the problem re-appeared, I have mainly been doing routine computing. I have kept the system up-to-date using apt-get upgrade and apt-get dist-upgrade. The only other notable incident was a power failure. I do not have the computer connected to a UPS, so the power failure resulted in an immediate shutdown. Could this have corrupted an important file which must be accessed at shutdown? Is there any way that could cause a 5-minute hang-up? Here is a list of packages that have been updated before the problem appeared: bash iotop dpkg dpkg-dev python3-software-properties libdpkg-perl software-properties-kde software-properties-common akonadi-backend-mysql libakonadiprotocolinternals1 akonadi-server firefox-locale-en firefox flashplugin-installer libqapt2 libqapt2-runtime thunderbird openjdk-7-jre-headless thunderbird-locale-en kubuntu-driver-manager qapt-deb-installer openjdk-7-jre qapt-batch icedtea-7-jre-jamvm libelf1 dpkg dpkg-dev libdpkg-perl libjbig0 gettext-base libgettextpo-dev libssl1.0.0 libgettextpo0 libasprintf-dev linux-headers-3.13.0-24 gettext libasprintf0c2 linux-headers-3.13.0-24-generic openssl linux-libc-dev gstreamer0.10-qapt kubuntu-desktop linux-image-extra-3.13.0-24-generic linux-image-3.13.0-24-generic I would appreciate any help with this.

  • Huawei E3276 LTE uplink slow in the routing Ubuntu, but not with other devices in the LAN

    - by Mytomi
    I have a Huawei E3276 LTE dongle (12d1:14fe - 12d1:1506) and a problem with the upstream speed. The problem is not only present with Ubuntu 14.04 LTS (64 bit workstation, kernel 3.16), but also with Raspbian Jessie for Raspberry PI (kernel 3.14). Upstream seems to be always limited to 5 Mbit/s whenever I check the speed from the Linux computer that I use as a LTE router. The other computers in the LAN always get about 10-15 Mbit/s upstream, even though the traffic is routed through the same Linux computer suffering from seemingly capped uplink. Downstream speed is always fine, 25 Mbit/s. I even installed Windows 7 in the same computer as Ubuntu and the speeds are 25 Mbit/s down, 15 Mbit/s up. So the problem is not with E3276 device itself or in the mobile subscription, but in the Huawei E3276 Linux compatibility. Maybe something in the kernel? I have made sure that the matter is not with iptables rules: the speed does not noticeably increase when iptables is disabled. Turning off IPv4 forwarding does not improve speed either. I'm not sure what settings and logs do help in debugging the situation. Please ask for more details, if you have a clue what might be wrong. Thanks, Mytomi

  • USB modeswitch to mass storage device

    - by Andrew
    I'm trying to install a Sierra AirCard 320U (branded as "Telstra USB 4G") into a VirtualBox Windows XP machine, on an Ubuntu 10.10 host. usb_modeswitch offers me a way to disable the "mass storage device" option, but I can't see a way to permanently re-enable it so it's usable by VirtualBox (device filters briefly detect it but then it disappears again). lsusb shows the device as: 0f3d:68aa Airprime, Incorporated When I first insert the device, it shows as 1199:0fff Sierra Wireless, Inc. Is there any way to re-enable the storage device so VirtualBox can see it?

  • Huawei e303c data-card not working for Ubuntu 11.04?

    - by Umashankar
    Cheers to you. I got a problem in making a Mobile-BroadBand connection in Ubuntu 11.04, using 'Huawei e303c' usb data-card. I'm using Tata Docomo 3G sim-card (India, circle: Maharastra). My observations: 1.) I installed the device's driver 'Mobile-Partner For Linux'(which came up with the device). But it is not detecting my device. 2.) In Network Manager, Adding a Mobile-BroadBand connection is not able to detect the device (with or without the device's driver installed). 3.)I tried softwares like usb_modeswitch, gnomeppp, wvdial, sakis3G and followed their guidelines. These too didn't work. 4.) Without the driver, the system is able to identify the device (Mobile-Partner icon comes-up, that leads to driver setup files). But after installing the driver, nothing comes-up there. 5.) In all the above cases, when 'lsusb' cmd is fired, the prompt shows the connected data card (as 'DEVICE_ID:VENDOR_ID Huawei Technologies Ltd.,'). This is my problem. Give a solution to get my device connected. -Umash

    If I have a wireless and a usb internet connection on my Ubuntu 12.04 as in: At the moment, Ubuntu seems to only make use of the Wired connection which is the usb connection. Is it possible to get ubuntu to use the wireless connection without unplugging the wired connection? So basically, as will, I would like to switch between the connections without unplugging any of them while leaving them both enabled. Is this possible?

  • 3G dongle and memory card detection

    - by user212632
    My questions is about 3G dongle (Huawei E1752) that I use for my internet on Ubuntu 12.04. The big issue is that ubuntu only recognise the dongle if I plug it in before booting up. But if somehow I loses connection (due to network being low) then the only way to use the 3G dongle again is to reboot my machine, which becomes a pain. I have the same issue with the memory card reader of my laptop whereby it only reads when I insert the card before booting up. My laptop is an Acer V3 -571g. At first I thought it was an issue that the model was quite new, but I have been updating my ubuntu for a while, and this issue has kept being the same

  • Windows with putty via USB serial cable to Linux serial port - output ok, input isn't

    - by Aharon Robbins
    I am trying to get two way serial communications going between a Windows XP system and a Linux system (RHEL 5). I have /sbin/agetty -L 9600 ttyS0 in /etc/inittab. I am using a generic USB to serial adaptor on Windows (Unitek) and a null modem cable. I have putty configured for 9600 baud, 8 bits, no parity, one stop bit, no flow control. I get the login prompt from agetty in the putty window but input does not work; I see weird characters in the putty screen. I can echo output into the device from windows and see it, but cat < /dev/ttyS0 just prints out weird characters from what I type. Any and all suggestions will be welcome. Thanks!

  • Splitting Ethernet cable

    - by Nathan
    I am looking for the best way to network my small business. I have an office where my router/modem are located, and then 2 more computers in another room. I can route Ethernet to this room with about 75 ft of cabling, and I would like to do this because my computers on Ethernet are getting 3x the speed as computers on wireless. Is there any way I can use just one Ethernet cable to span the 75 feet, and then maybe 2 smaller ones to go to the two computers from there? If there's a simple way to do this, maybe with a connector that would be ideal, as opposed to buying over 150 ft of cabling. Thanks!

  • Using ADSL Modem/WiFi Router to share existing network wirelessly

    - by joshhunt
    At my uni we have a wired Ethernet connection in our dorms. However, I want to share this connection with my macbook using wifi (so I don't have to be constantly tethered). I am looking at using my DSL G064T ADSL modem/WiFi router as a wifi repeater for the uni network. Is this possible? How would I go about doing this? I understand that it would be possible using a normal Wifi router (seeing as it has an ethernet 'in' port where it would get the external connection from.), so is it just not possible using the router I have? If i need to buy another one, which one would you recommend?

  • LG W3000H-BN monitor cannot go above 1280x800

    - by Jo Profit
    I noticed that there are many people complaining about this issue with the W3000H but I have yet to find a solution that works for me. I am using Windows 7 Professional and and using a nVidia Quadro NVS 240 video card with a 4 monitor splitter cable. The cable from the monitor and the splitter are rated DVI-D Dual Link and the video card itself is rated for 2560x1600. I have installed the latest drivers for the video card and just grabbed the .inf, icm and cat file from the LG website and manually installed the monitor drivers. Does anyone have problems with the same setup? I have 3 other monitors (2 at 1920x1080 and 1 at 1280x1024). I really would like to be able to display the full resolution or else the large screen is useless. (I triple checked that the monitor itself supports this resolution). So monitor, cable, splitter and card supposedly support 2560x1600. Drivers are up to date but I cannot select that resolution when in the "Screen Resolution" menu, nor through the nVidia control panel. Please save me from madness :)

  • Multi sim GSM modem or alternative

    - by Ando
    I'm trying to administer the SMS trafic of my businesss centrally through a web portal. In Europe (except UK) we don't have a numbers/SMS trafic provider like Twilio or Clickatell, nor any build in way to administer the SMS traffic for a number via http, so I will have to buy the long numbers and administer the SMS traffic myself. For this I was looking into a hardware solution for hosting all my SIM cards - I have like 400 sims cards (= numbers). I saw that GSM modems might fit in but they don't seem to scale up very well. Could you recommend me a GSM modem? If this is not the best way to approach this, what would my alternatives be? Thanks in advance
