How to check if USB ports (environment) available and accessible ??

[Mark Spitzer]

I have a problem to get my USB scanner working under Win2000 Prof.
After I plug in the USB cable it cannot be seen by the Win2000
("Sorry, scanner could not be initialized"/"Scanner not found").

I installed all the drivers and software several times but after all
I am still not able to access the scanner. The scanner itself is working succesfully
with other computers.

Is there a way to check the USB environment or to re-scan the USB ports similar
to a re-scan of SCSI peripheral devices?

Or something like a most simple "ping-to-USB-device" showing if the USB device
is accessible at least on the lowest hardware level?

Make sure the USB is enabled in the BIOS.

I'd try deleting all references to the USB root and hub in the device
manager, then redetecting them (and reinstalling the proper software).

A low-tech way is to shut down and unplug your mouse. Then plug a USB
mouse into one USB port, restart the computer, and see if the mouse gets
recognized. If it does, then you should be able to plug from each port
and plug into the next without shutting down.
