USB not recognized with flash drive only

[patio]

Just for clarification...front or rear USB ports being used ? ?

[roshcats]

Ok, it just got finished running and restarted the computer and still have same issue, ? They are the front USB but I plugged into the rear USB and get the same USB not recongnized.  What next?

[patio]

Plug one into the PC they work on...
Right clik My Computer and select Manage...then Disk Management...
Find the Flash drive...right clik it and select Properties...

Report back with your findings...

[roshcats]

Kingston
Type: Removable disk
File System FAT32
Used space 1.39MB
Free space 7.44MB

If there is more needed from this let me know

[patio]

Travel to Device Manager on the troubled machine...
Expand all USB listings for roots and hubs...
Right clik every instance and select "Remove"...
You will recieva a warning message...ignore it.
Do this for all of them then re-boot.
Windows will automatically re-install them.

Ok, here is what I saw and did.  By your directions, if I interrupted them correctly, I right clicked the USB hub under device manager and then I did not get a remove option but insteed I un-installed them because that is the only option I saw,  I hope this is the same thing.  I had 4 root hub USB showing under the USB option.  Three of them un-installed and disappeared as I un-installed them, but one of them would not un-installed and stayed on the device manager.  I left the USB mouse and USB printer plug in during all this and did not un-install them, I hope this is correct,  I restarted the computer and plugged the flashdrive in the top front USB port and still got USC device not recognized.  Moved it to the lower USB drive port and it stated "new hardware found"  Then it stated "USB might not be configured"  I think, because it went by so fast.  Then it stated "USB device not recognized".  Let me know what is next, please.  I do want you to know I am very grateful for your help.

Well you did it correctly...but i've never ran into one that would NOT un-install...
Did you uninstall the roots and hubs ? ?

If not try again...

Ok here is what I am looking at under device manager for USB, I put the number beside items for easier reference:
Universal Serial Bus controllers
  1. Officejet 7300 series (DOT4USB)
  2. SiS 7001 PCI to USB Open Host Controller
  3. SiS 7001 PCI to USB Open Host Controller
  4. SiS 7001 PCI to USB Open Host Controller
  5. Sis PCI to USB Enhanced Host Controller
  6. USB Composite Device  - when the flashdrive is plugged to the front upper USB this USB states "unknown device"
  7. USB Mass Storage Device
  8. USB Mass Storage Device
  9. USB Printing Support
 10. USB root hub
 11. USB root hub
 12. USB root hub
 13. USB root hub

I started un-installing 10 through 13 only and nothing else and when I got done it looked like this.  The USB root hub in the #12 spot would not un-install.
  1. Officejet 7300 series (DOT4USB)
  2. SiS 7001 PCI to USB Open Host Controller
  3. SiS 7001 PCI to USB Open Host Controller
  4. SiS 7001 PCI to USB Open Host Controller
  5. SiS PCI to USB Enhanced Host Controller
  6. USB Composite Device
 12. USB root hub

After a restart it was back to like the top and I plugged in the flashdrive and it again stated USB device not recognized.   Let me know if I did something incorrectly and I will go again.

Add 7 & 8 to your list of un-installs.  USB flash drives are the USB mass storage devices.

[patio]

I'd suggest unplugging all but the neccessary USB devices (mouse/keyboard) and re-booting and repeating the steps...

I've just never heard of anything like this problem before. I'm following this thread with great interest.

You too eh?

[roshcats]

Ok the only USB device I had plugged up was the printer and I unplugged it.  Now in device manager I have:
Universal Serial Bus controller
  1. SiS 7001 PCI to USB Open Host Controller
  2. SiS 7001 PCI to USB Open Host Controller
  3. SiS 7001 PCI to USB Open Host Controller
  4. SiS PCI to USB Enhanced Host Controller
  5. USB Mass Storage Device
  6. USB root hub
  7. USB root hub
  8. USB root hub
  9. USB root hub
Again there is nothing plugged into any USB port keyboard and mouse are on PS/2 ports.  Which of the above items should I go in and un-install and does the list above look correct with nothing plugged in?

[patio]

5 thru 9....
Remember to clik on them to expand them as well and remove all the entries...

[roshcats]

Ok, I un-installed 5 through 9 and restarted the system.  When it came back up I got some error codes.  I don't know if they are important but here is what they are.

BCCode: 1000007e  BCP1: C0000005   BCP2: 00000000  BCP3: F7A08A18  BCP4: F7A08714  OSVer: 5_1_2600  SP: 2_0 Prod: 768_1

Got past those and plugged in the USB and I restarted the computer and plugged the flashdrive and it stated "new hardware found"  Then it stated "USB might not be configured"  I think, because it went by so fast.  Then it stated "USB device not recognized" again.
