• Wired and Wireless USB Network Adapter

  - by Evan M.

  Does anyone know if there are any USB network adapters out there that have both wired and wireless networking capability? Far-fetched, I know, but thought I'd ask. Background: Some of our users have locked down laptops that we also include unlocked virtual machines running on VMware Player. Sometimes the users have a need for network connectivity with their VMs where NAT and bridged networking from the host won't work. To supplement this, we want to supply them with adapters that they can use VMware USB pass through capabilities to provide appropriate connectivity. They will need both wired and wireless capability. Rather than carrying around 2 adapters, was hoping we could get a combination unit so that we can reduce it to 1. Thanks

• Cross platform support for network attached USB hubs?

  - by larsks

  I am looking at network-attached USB hubs in order to run licensed software in a virtualized environment when hardware dongles are required. Are there any solutions that will work with both Linux and Windows? Most of the dedicated devices -- such as the Zonet ZUH2214 or the (oddly expensive) Digi AnywherUSB/2 -- appear to be Windows-only. Linux has the the USB/IP project, for which there appear to be Windows drivers, but the last "News" post on the site was in 2007, so I'm not entirely confident about the viability of the project. Has anyone out there found a solution that will work well in both environments?

• Gigabyte GA-P55A-UD4P won't boot from USB drive with RAID enabled

  - by Daniel Schaffer

  I've got a Windows 7 installation image on my USB hard drive, which is set up to be bootable. I know it works because I've used it on several computers, and it works on the computer I'm trying to install as long as the RAID controller is disabled. However, when I enable the RAID controller and attempt to boot from the USB driver, it hangs for 30-60 seconds and then gives me the "disk boot failure, insert system disk" error like it can't find any OS. Just for laughs, I disabled the RAID controller again and it booted fine. I'm having separate, unrelated issues burning a dvd with the ISO, so I would prefer to get this working.

• USB hard drive doesn't graceful power off after eject on Windows 7

  - by Sim

  I have a couple of Seagate FreeAgent Go external USB hard drives and would like them to gracefully power off after ejecting in Windows 7. With Windows XP a few seconds after they are ejected they gracefully power off. When ejecting them on Windows 7 they just stay on and have to be physically disconnected before they lose power. I have checked the hard drive removal policy and it is set to quick removal. I have also looked in the Seagate forums but I couldn't find any info on this so I thought I'd ask the SuperUser community on any ideas why the difference and how to get the same behaviour in Windows 7 as in XP? Update: I am finding that this also happens with USB thumb drives as well. My current theory is that there were changes to the driver model with Vista/Win 7 that haven't been reflected in the device drivers yet. So things that worked under XP don't under Win7 as the drivers haven't been updated for the new model. Does that sound right?

• What is polarity for an unmarked USB hub?

  - by Feral Oink

  On my USB hub where the power supply plugs in, the polarity is unmarked (I got it used, from my brother's friend). I need to know what the polarity should be. I don't think it makes a difference about the brand. Could someone who has a USB hub tell me what the polarity markings are? This is why I need to know about the polarity: Usually the center pin is positive and the outer pin is negative. But I'm not sure with this, and want to be certain before I plug anything into it.

• Create Hidden Partition on USB

  - by Francesco

  I need to split an USB flash disk into two USB drives, each one with its own drive letter, but one of these has to be hidden. In the non-hidden partition I want to place my software, and in the hidden partition I need to place some files that are required by the software in order to work. Moreover, only the software may read, write, delete or execute the files in this partition. I thought to use a little partition viewed as a CD-ROM drive, as they do in many flash drives, but this solution does not allow to write other data in a second moment, and it's visible to the user that can read the file. Obviously the software must be able to access to partition and read, write, delete or execute the content. Is there a solution to do so, possibly that work also on Linux?

• Multiple LiveCD iso's on a single USB drive

  - by Keck

  I am looking to create a USB flash drive that I can put multiple LiveCD iso's on and select which boots from startup. The ideal candidate supports linux and windows based iso's, and is relatively simple. It also must have some reasonable process for adding and removing iso from the drive/list. Things that I'm not looking for this specific question: UBCD or other swiss-army knife livecd's. The point is to boot any one of multiple CD's, not to boot a (certainly useful) utility CD. Installing a single LiveCD to a USB drive. I'd like to have multiple iso images, selectable at startup. I don't have a specific purpose in mind, possibilties include a single drive with a knoppix variant, ubuntu desktop, UBCD for dos, UBCD4Win, the Offline NT Password Cracker, etc. Flexible and easy to use are the name of the game!

• auto copy newest folders and images in MyPictures folder to USB drive

  - by TVersmet

  I drop lots of photos in a day into the My Documents/My Pictures folder. I archive at the end of each day to USB drives, to be stored offsite. What I would like is someway to automate the process. By example, a small app or script I can simply double-click and it will scan the My Pictures folder for the newest folders and images and copy them to the USB drive until the drive is full. It doesn't matter if I get redundancy from the previous days saved images, so long as the newest images and folders are always the first to get copied. Well, that's my request. Thanks for reading.

• Prepare bootable Mac OS install usb on Windows

  - by Dave

  Hello, Is there any software out there that can simulate Disk Utility (Mac app) for Windows? I need to reinstall leopard on my Mac because I screwed something up on the current OS. The thing is, the DVD drive is broken on there, so I need to prepare a bootable USB drive from my Leopard DMG file. This is easily done with the Disk Utility app on the Mac. But seeing how my cannot even log on to my Mac right now, I don't know how to prepare that USB stick. The only other machine I have is a PC with Windows 7. If anyone has any suggestion, please help me out! Thanks so much!

• USB drive gets infected every time I plug it into my laptop

  - by ashwnacharya

  Whenever I plug in my USB flash drive into my laptop running Windows XP, an AutoRun.inf file gets created inside it. Also a hidden folder called "Cache" which uses the Recycle bin icon gets created. AutoRUn.inf file cannot be opened in Windows. Both the Autorun.inf file and the "Cache" folder cannot be deleted. I opened the AutoRun.inf file using Ubuntu. I saw that it is trying to run a file Cache\TMP983.exe. I ran all anti-spywares, anti-malwares, anti-viruses, USB autorun eaters, but to no avail. How do I fix this?

• USB Audio device not selectable in settings after Camtasia Studio

  - by DJDavid98

  I tried to use Camtasia Studio 7 Recorder today, and when I selected the "Record Microphone and System audio" option, the recorder crashed, and then my sound settings icon disappeared. If I tried to open the Camtasia Recorder's Options or tried to select the option again, the program crashed. After holding the power button to force restart (so My settings wouldn't save, theoretically) the audio device was still not showing up in the sound settings, although it still is displayed under the "Hardware" tab, and is Functional. Or at least that's what windows thinks. I tried uninstalling Camtasia, and no sucess either. The USB audio device is labeled "C-Media USB Headphone Set". OS: Windows XP SP3 hu-HU Is there any way I could make it work again, like registry editing or something?

• Mac Mini won't boot with USB Drive connected

  - by Jens

  Newbie here. I have a 2012 MacMini with 2 x 3Tb Seagate GoFlex Desk external hard drives. Both drives have their own power supplies and work perfectly. I use both MacOS and Windows7 on the Mac for different reasons. Both boot and work fine. The only problem is neither MacOS or Windows will boot while the two USB drives are connected. I must disconnect the USB cables, boot and reconnect them. Then all works fine. Its rather annoying since this is mostly a Media Centre and you really don't want to be playing with cables every day, and I don't leave my stuff on over night. Can anyone help? Thanks Jens

• Shopping for Fast USB Flash Drives

  - by Jim McKeeth

  I would like to pick up some really fast USB flash drives in the 16 - 64 GB range. When looking at drives they just list their size, their form factor (key chain hook, slider, etc.) and the fact that they are all Hi-Speed USB 2.0. It seems like I have heard that different drives have different performance and life expectancy. The sales guy tells me that they are all the same performance any more, but it wouldn't be the first time a sales guy had the wrong technical details. Our objective is to run Virtual PC images off of them, so good speed and resilience to rewrites it important.

• Windows - Delayed Write Failed error on USB hard drive

  - by ndngrd

  I've got a new Verbatim 1.5TB USB hard drive (Samsung HD154UI) and I'm finding myself completely unable to fill it. I'm using Windows XP. Whenever I try to copy a load of files over, it works for some time (will copy over between 20 and 90GB) but eventually stops with an error saying "The specified path is too deep" - the specified is not too deep, there's nothing more than 2 dirs deep that I'm copying. A balloon pops up at the bottom saying "Windows - Delayed Write Failed" telling me the data could not be copied. This wouldn't be too bad if I could just restart the transfer, but after this error has happened I can't write anything else to the disk - including if I eject it and then connect it to another machine. It just seems completely locked. The only way I can unlock it is to delete everything that I was copying to it. I've tried various USB cables and copying from different machines, and the same thing keeps happening.

• USB to IDE/SATA adapter

  - by unknown (google)

  I have an old IDE HDD that I am trying to pull files off of. I am using a USD to IDE/SATA adapter. I plug in the power and adapter plugs into the drive and it fires up. I plug the USB plug into my XP laptop and it installs the drivers. I can see USB Mass Storage Device under Device Manager. My problem is I can't see the drive in either Windows Explorer or under Disk Management under Computer Management. Not sure what I am doing wrong. Do I have to slave the old hdd? Do I have to make BIOS changes?

• USB flash drive unreadable after a few minutes on Windows 8

  - by B Sharp

  I recently got a new computer with Windows 8. I a have a number of large backup files I am moving from my old PC to my new one. I was able to successfully copy the files to a couple 16 GB flash drives. When I try to copy the files to my new computer, the process starts just fine but after copying about 4 GB of files, the copy stops. If I look at the drive in explorer, the drive is there, but I just get a busy cursor that stays indefinitely if I click it. If I unplug the flash drive and plug it back in, everything is fine again... for a couple minutes. I've tried copying from both flash drives with the same result. I've also tested this on the USB 2.0 and 3.0 ports on my motherboard with the same result (the drives are USB 2.0) It's also puzzling that this is happening since I previously used one of the same flash drives to install Windows 8 on this computer in the first place without any difficulty.

• Boot time virus scan from USB drive

  - by Tomas Sedovic

  I want to check for viruses on a computer that I suspect may be infected with malware. Its users are running an antivirus, but there's always the risk that something slips past and the way I see it, once the system is infected the antivirus is useless because the malware can hide itself from the AV. I think the best way to go (besides clean reinstall of the OS) would be to have an antivirus running at a boot time from a CD or a USB key. That way, the malware is just lying on the disk and cannot do any of its hide-and-seek stuff (provided the AV comes from an uninfected PC and all that). So, I'm looking for something that: Runs at boot time (off USB key or CD-ROM) Does not touch or require the local OS Discovers malware fairly well (like, Avast, AVG, Norton, whatever -- I think the're all the same anyway) Can handle Windows filesystems (FAT 32, NTFS, WinFS ;-) ) Comes from some sort of trusted source (no Windows Antivirus 2009) I know that this is no silver bullet (nothing is, really*), but I do have a feeling it's more likely to help than doing the scan* within the infected system.

• PC doesn't boot PC-BSD from USB

  - by turlando

  I've got a problem with a friend's PC: I'm installing a FreeBSD server and to make easier the installation for my friend I'm using the PC-BSD DVD. Surprise! The CD reader doesn't read DVDs, so I'm using a USB stick to perform the install. The PC seems supporting USB boot because I can choose it in the boot sequence, but the PC-BSD installation doesn't start, booting the OS installed in the primary HD. I have not physic access to the PC and I can't have at the moment more informations. What do you think about? Thanks and sorry for my terrible English. Tancredi Orlando.

• USB-Sticks and multiple Partitions

  - by Bobby

  Hello. I've got an USB-Stick with multiple Partitions on it (FAT32 (active), FAT32, Ext2 <-- that's another story) and it seems like that my Windows XP can only mount the first partition of the stick. If I try to mount the second one using the volume manager it tells me that I need to make it active and reboot...is it really that limited or am I just missing something here? Partitions: FAT32, System Rescue CD, bootable and active FAT32, some tools ext2, some data (I know that I need extra drivers etc., but that's not asked here. Edit (Solution): Thanks to the answer with the RMB (ReMoveable Bit) I was able to dig up a solution described at this site (Section: On flash drive only the first partition works). Basically, there's an Hitachi Driver available which filters the RMB on Driver-Level, which just needs to be a little modified to function with basically every USB-Stick. All you need to do is adding the "Device Instance ID" to the driver and then use this driver.

• Repair snapped USB flash drive

  - by Richard Slater

  I have a USB Flash Drive that has had the USB connector snapped away from the circuit board. In the past I have had great sucess with soldering the connector back to the circuit board with 4 solid core wires. Unfortunatly this particular device shows up as "Unknown Device" in device manager and displays 0ma power usage. Giving a closer look at the circuit board it appears that the Data + connector has come away from the PCB. Which would explain why it is not recognised. Is there any practicable way of lifting the data from the device? larger version

• portable usb harddisk regardless in windows and ubuntu / linux environment

  - by user8184

  I am doing web development mostly in ubuntu. Sometimes i need to go into windows to do other administrative work. Now i am ignorant about file systems. I cannot tell the difference between NTFS and FAT32. My eyes just glaze over the wikipedia articles. All I know is i have been using this 320 Gb portable USB harddisk to save files when I am in ubuntu and when I am in windows. Now i got a situation where sometimes the windows 7 cannot detect the harddisk. I believe it has to do with the file system issue. Or my harddisk is coming apart. To make it easy to backup my files in a portable USB harddisk regardless in ubuntu or windows, please advise me. That means i can go from from linux/ubuntu to portable harddisk read/write files from windows 7 to portable harddisk read/write files the same files. Thank you.

• How to install OSX into VirtualBox on a Macbook Air using Apple's Reinstall USB

  - by eug

  I'm currently dual-booting OSX and Ubuntu on my Macbook Air, but it'd be nice to run OSX within Ubuntu via VirtualBox. This seems possible using VirtualBox and is legal - there's even a post on an Oracle blog describing this: http://blogs.oracle.com/karim/entry/installing_mac_os_x_in. Actually, I've read elsewhere that it's only legal with OSX Server, but can't find a reason why it'd be illegal with normal OSX - please let me know if you think otherwise. The problem I have is that a MacBook Air doesn't come with a bootable DVD, but with a "Reinstall Drive" which is a USB stick that comes up as a CDROM drive. It doesn't seem to be ISO9660-formatted though but has an Apple partition table, with OSX installed on an HFS partition. refit says that it has a "boot.efi" as well. I don't know Apple booting/partitioning very well and would really appreciate some advice on how to convert this USB into an ISO or boot it in VirtualBox some other way.
