USB Driver Not Working

Hi
I have tried all possible things of reinstalling itunes, mobile driver as well as my PC USB drivers.
I looked up through Apple support pages and found out that my ipod is being detected as "Unknown Device" in my USB tree in Computer's device manager. I also tried updating my device driver but the computer is giving a message that the driver is completely updated.
I searched from one of the forum's threads that there is a file 4ea12.msi which needs to be uninstalled and then reinstalled. To my surprise this file is missing in my computer. Can this be a reason ?
I am going for a vacation tomorrow and I want to carry my ipod. It would be great if I can get some assistance.
Regards,
Shamit

Hi jo_calvin, and welcome to the HP Support Forums!
Just want to make sure that I understand you. You have a flash drive and an external hard drive that will not work in your USB ports and when you checked in Device Manager it is not showing the USB port being installed. I will try my best to help you resolve this issue.
To better guide you, could you please tell me the full model number or product number of your computer and the operating system that is running on it. Here are a couple of guides for How Do I Find My Model Number or Product Number? and Which Windows operating system am I running?
I am including this document for Troubleshooting USB Connections (Windows 7) in hopes that these steps will resolve your issue.
Please let me know how it goes.
Thank you and have a great day!
I worked on behalf of HP.

USB drives not working right in kernels 3.7.6

On any kernels > 3.7.6 USB drives are taking a very long time to show up and I'm getting a lot of these:
Feb 16 06:45:40 archy kernel: usb 1-3: device not accepting address 3, error -110
Feb 16 06:45:56 archy kernel: usb 1-3: device descriptor read/64, error -110
Feb 16 06:46:11 archy kernel: usb 1-3: device descriptor read/64, error -110

Feb 16 06:46:32 archy kernel: hub 1-0:1.0: unable to enumerate USB device on port 3
...in my log. Does anyone know if there were any USB related changes to the kernel recently or have any ideas of things I could try besides downgrading my kernel?

Me too! Same message from journalctl. kernel 3.7.7, with several usb devices (hdd, pendrive, dvb-t tuner).
I'm waiting for linux-3.7.8.
Gooberslot, what's your kernel version?
Edit:
Ok, it's a bug related to ehci_hcd module, kernel 3.7.7 and 3.7.8 are affected:
Currently (on 3.7.8), only manually reloading (modprobe -r ehci_hcd) ehci_hcd works.

USB drives not working on Macbook Pro

I have an early 2011 Macbook Pro and both USB drives are currently not working. All storage devices work in my other Mac, just not in this one. They do not show up in disk utility or anything. I've attached a screenshot of the system profiler information, because when compared to my other Mac it doesn't show as many USB ports. Please Help, Justin

Hi i'm also having the same problem (Macbook pro late 2011). I have a back-up hard drive that will not connect to my usb either. I have done a PRAM & SMC reboot and neither worked. I read another post that said to erase the usb & retry connecting, but that's not really an option for me as this is the back-up of my entire disk + extra materials (I'm a medical student). I need the data off my hard drive urgently! It was working this morning and now it's not.
Mine does show up in disk utility, but I can't access anything on it. Any help would be appreciated! Thanks!

Apple Mobile Device USB Driver Not Working (Code 10)

i have a windows 8 laptop and the "Apple Mobile Device USB Driver" in the Device Manager recently stopped working, it has this little yellow triangle with a '!' in it next to it. i have restarted my computer/iphone several times, i've reinstalled itunes a few times, i've tried different USB ports and different cords.
it also says "This device cannot start. (Code 10)"
Please let me know if you have had and fixed this problem
thanks

Yep...^^
I just fixed my ipod nano problem on my own and figured I'd share as I have just spent the last 4 hours trying to trouble shoot all of Apple's problems...following everyone's tips...nothing worked until I figured it out on my own.
I'm running windows 7 and have an Ipod Nano (6th Gen). Hard drive crashed on computer. Replaced HD. Everything works fine now. Downloaded iTunes along with all other programs. Nano wouldn't show up or sync on iTunes. Said Device Driver Software was not successfully installed (some USB problems). Tried everything. Finally, I figured it out.
Disconnect Nano. Uninstall iTunes AS WELL AS
Apple Application Support, Apple Mobile Device Support, and Apple Software Update. Apple only
tells you to uninstall iTunes and reinstall..restart computer bla bla bla. I said screw it and uninstalled all Apple programs (well, the listed ones above). I hooked up my nano to my computer to make sure the device manager recognized it without anything else plugged in...and it did. I unplugged it. Reinstall iTunes and all three other Apple programs listed above will also reinstall. I opened iTunes and plugged in my nano. It started with the "installing device driver software" and I was sure
it wasn't going to work. Well, it did work. My nano showed up in the upper right bar of iTunes and synced. Unreal... I unplugged my nano and plugged in the wife's. Once again, "installing device driver software." Voila! Her's showed up and synced too. I plugged mine back it to make sure it worked and it did. I'm done. It's working. Hope these steps work for you as well.

Iomega external USB drive not working

Hello, I have a K8n neo4f board, 1.9 bios, AMD64x2 4400. For some strange reason my external USB drive doesn't work with this setup. I get i/o or insufficient resource errors, and the system will hang. This is puzzling since I have plenty of system resources available (2G ram), and my USB inputs work with other devices. I currently have a dvd drive, ir receiver,memory card adapter, and a cordless mouse receiver plugged in. All of these devices work flawlessly. There is nothing wrong with the external drive, it works with my Dell Inspiron 8200 Laptop. Is this a bios issue, should I upgrade to the latest 1b ? I'm hesitant of doing so, because of the horror stories I've read in this forum of systems becoming unuseable. Maybe someone with a similar problem can help me out.

Are you sure this is not software related .

Webcam and usb drive not working--possible hardware issue?

Hello,
I recently purchased a Lenovo ideapad U510 with Windows 8. I bought it as a returned machine but the Staples employee didn't know why it had been returned and thought it was just because the buyer didn't like Windows 8. When I first set it up I kept getting an error message that my usb device was not recognized, even though I had never plugged anything in. As I was leaving the country, I dismissed the issue and decided to deal w/ it when I returned to the US, since my other usb drives worked fine.
However, later my integrated webcam stopped working as well. It worked one time when I used Skype but not after that. I checked online forums for possible solutions, and most said I needed to download an updated driver. I didn't think this was the issue b/c when I went to device manager and tried to update my driver for the easycam, it said I already had the most up-to-date driver. I have uninstalled drivers, downloaded and re-installed drivers, and even refreshed my computer, all to no avail.
Here are the error messages I receive:
In device manager>view>show hidden devices>imaging devices>Lenovo EasyCamera, device status says
Currently, this hardware device is not connected to the computer. (Code 45)
To fix this problem, reconnect this hardware device to the computer.
When I try to run the Bison setup: Lenovo EasyCam has not found!
When I try to run the Chicony setup: Setup failed! Please Plugin camera and install driver again!
So, I'm thinking it's not a driver issue, but I'm not a techie and don't know what else it could be. Wondering if the usb problem and webcam problem are connected. Found another forum post that said maybe the webcam is not connected to the motherboard...suggestions?
Thank you in advance for your help.

I am certain it is a hardware issue from the problems youre describing. I would contact Lenovo. They may try to have you purchase their "software" support, but don't let them. I had wifi issues and they tried to make me spend $90 because I was too lazy to figure it out on my own.
Make sure when you're calling support that you tell them that you restored to factory default and before you send your computer in, back up your data. Also tell them that it's a new computer and you do not want to pay for shipping... They will most likely comp you shipping in both directions.

USB Drive not working since G5 crashed while writing to it

I was using my external hard drive to back up on, as usual. However, my G5 crashed while writing to the drive. And it hasn't worked ever since.
I have tried using the disk repair utility to re-partition the drive. But the progress bar goes to 2% and stays there, ie it starts trying to partition the drive and then literally sticks there.
The same thing happens on windows by the way. However, there is a utility from Maxtor which tests the drive and says it's physically fine.
Diskwarrior wasn't able to even recognise that the drive was there (yes it is plugged in! ;-p)
Hmmm... is there anything else I can try to get the drive formatted?
Cheers
Alan

By the way, I've tried to use Disk Warrior but it doesn't even recognise the drive as something it can test. Only the main hard drive comes up in the drop down list...

Have you done:
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
or
Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7
What results do you get when you run this:
iTunes for Windows: Device Sync Tests
Do both the Home button and Power button work OK normally?

HT2801 USB Super drive not working

I have removed the optical drive from my 2008 (late) macbook and added an SSD to run along side the HDD and increased the RAM. I have a super drive to read CD/DVD's but i can not get this to operate?

I believe that the Apple USB Super Drive only works with late model Macs that didn't come with an optical drive. Third party usb drives will work ok though.

Windows 7 (Ent) Sp1 on server 2012 R2 HyperV, RFX USB redirection not working

Hello,
I currently have windows server 2012 R2 with HyperV installed. I have built two virtual machines. A windows 8.1 and Windows 7 sp1. Both are enterprise editions
For RemoteFX the hypervisor is using a Zotec GTX 760 GPU. It recognizes it and uses it to apply remoteFX adapter on my Windows 7 Sp1 VM.
As you are aware I do not need to use a GPU to enable RFX on my Windows 8.1 it can do this without the need of a GPU.
Using an RDP client( v8.1) I can connect to my Windows 8.1 VM with a USB headset,memory Key or a printer and they all enumerate on the Virtual machine. The driver for each device installs
and I can use the device without any issues.
However this issue lies with the Windows 7 SP1 VM. I can connect to it via RDP( Same client) but I cannot redirect any devices to it. I have installed the latest integration services available on the VM. I have ran all updates available.
Because I have ran all updates the rdp version on the VM is running v8.1.
Previous to installing the updates USBr still was not working
I have enabled the following group polices under remote desktop services on the Windows 7 SP1 VM :
RDP 8.0 -- Enabled
Configure RFX -- Enabled
Is there a known issue with USB redirection not working on a Windows 7sp1 virtual machine hosted on server 2012 Hypervisor ??
Many Thanks
Brian

Hi,
According to the log above, I found that we run the script on both Server6 and Server7. Errors as below:
Server6: Conversion is not supported in restricted language mode or a Data section.
Server7: Couldn't figure out valid servers from the specified destination scope. Check your parameters and try again.
Since we can only run the RollAlternateserviceAccountPassword.ps1 Script on CAS server, the script not works well if Server6 is MBX server.
For Server7, based on the error message, it seems you still have no right to run the script/cmdlet.
Please add your account to Organization Management Role group(ADUC->domain.com->Microsoft Exchange Security Groups) to test if possible.
By the way, from Technet:
You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Client Access Security" entry in the Client Access Permissions topic.

After shutdown & start PC, choosing to boot windows 7 on bootmanager, USB devices not working in Win-7.

I tried to re-plug usb devices but notting happens... Still not working
But after the win-8.1 shutdown, if i switch off PSU power button, watting ~1 munute for discharge.
After power up PC and boot with windows 7 all usb devices works normaly.
I checked all internal connections. 2 times disassembly all hardware and re-built system, nothing changed.All windows updates and latest drivers installed.
I'm sure other H/W is OK, but I thnik this mobo have a fault.

Thank you for reply.My PC system specs:

All hdd's have MBR based partition table.Windows 7 & 8.1 installed in non-efi mode.In BIOS Boot sequence is setting up to non-efi Boot(system) drive as primary.
Before I suspect maybe have a short circuit to pcb or similar thing cause this issue.I take out all parts outside the chassis, and ran this system on the antistatic bag and box.Nothing has been changed.
I have Cooler Master Devastator(MB24 + MS2k) USB keyb+mouse set and tplink wn722n usb wireless dongle.
I have one more pc,based on AMD 970+SB950 chipset mainboard and AMD CPU.I exchange all parts to this amd mainbaord and tested for faulted hardware.All intel system H/W's is ok.All works great
Dual boot works perfectly.Not needs to switch off psu/power back and run system again.
I think msi z97-g43 mainbıoard have a problem.

SA30 USB do not work after reinstall, please help!!

Hi, my SA30's USB do not work at all after reintalling, I do not have the original CD with the laptop as it is a gift from my mate.... I couldnt find the driver from the website, please could anyone help me???
I could use the USB mouse but when I plug the external hard disk in, it has no responses, I tried to search for new hardware, it couldnt detect it. Any information would be appreciate, cheers.

When you instll another OS than the recovery OEM OS you have to install the drivers and tools in a right order!
This order is on the Tools & Utilities CD in a html file! When you follow these order all hardware should be detect!
Also you can go to http://eu.computers.toshiba-europe.com and download the drivers
