I'm having a problem whereby if I plug anything into my 4-port USB hub
the PC spontaneously reboots.
A little background:
I'm running Win2K SP4. I can plug devices into the root USB ports, it
is only when devices are connected to the hub that the PC reboots.
The 4-port hub in question was working just fine up to now. I've used
it for months, usually with a compact-flash reader. When I first got
the hub I just plugged it into one of the root ports and it was
detected and worked fine from the start. Anything plugged into the hub
would also be detected no problems.
I've tried various CF cards, same result. Again, it works fine when
plugged directly to the root USB ports.
I think this has something to do with my messing about today trying to
get a Castlewood Orb Drive working (parallel port version). I
succeeded in doing that, but now I think something I've done has
screwed up the USB hub.
I have tried uninstalling the "Generic USB Hub" from device manager,
then disconnecting and re-connecting the device. The hub is found OK,
but as soon as I plug anything into it WHAM! the PC reboots.
I have tried removing the usbhub.sys file which is apparently the
driver for the Generic USB Hub, in the hope that it will be replaced
(if corrupted) but this made no difference.
I've searched the MS knowledge base, and found an article suggesting
installation of SP4, which I already have. I reinstalled it just in
case but no difference.
I have searched the usenet archives and found a few souls who have had
similar problems but no solutions were offered.
Basically, I guess I want to force it to remove and reinstall the
necessary files in the hope that it will go back to what it was.
Strangely, it did work just one time when I removed and reinstalled
the Generic USB Hub, but after rebooting the problem re-occurred. Have
since re-tried many times without success.
Any ideas??
Thanks,
Markko
