USB disk driver error

Guest

Hi,
I have a PC running Windows 2000 Professional, I use a USB pen drive & a USB
external HDD.
These have both been working OK. but suddenly they have both stopped working.
When I plug in the pen drive:-
New hardware is found & drivers are installed but the installation fails.
Error message:-
The installation failed befcause a function driver was not specified for
this device instance.

This is the same for both the Pen & the external HDD, any suggestions?

Thanks

Try removing the devices for the USB controllers and the pen drive and
HD, and let Windows redetect them.

Hi,
Removed USB controller from device manager
Disabled USB in bios, rebooted in safe mode, checked in device manager to
make sure no USB controller listed.
Re-enable USB in bios, boot normally.

Device still doesn't work, shows up as unknown device in device manager.

It used to work though.

Delete it and see what happens when it gets redetected.

Hi,
Delete the device, still get error when it is reconnected.
Does Win 2K retain a record of attached devices - does it need removing from
there?

It retains all kinds of information, but generally deleting the device
from Device Management is sufficient. On the other hand, disabling the USB
controller will only hide the device, not delete it. You should leave the
controller enabled, delete the device, and then click on "Scan for Hardware
Changes" and let it re-detect the device.

If this still doesn't work, it sounds like either messed up .INF files
or failed hardware.
