USB "blacklisted" devices: how to remove them

"Robert Breunung" wrote in message ...
under system-variables u had to enter some string, then the option in the
devicemanager "show all devices" or "show hidden devices"(translated) works,
but i think restartin in secure mode is doing the same

Your USB adapter may just be bad...does it have the same problem if
you connect it to a different device?

Well I finally understood the problem.
The answer was in NG microsoft.public.windowsxp.general (cf infra).
So a driver can prevent windows generic mechanisms from doing
their job... but actually no "blacklist" is kept anywhere - at least
in this case.

Anyway it works and I feel much better now...
I sent the problem to Xilinx.

FYI

After using a flash card reader successfully for many months, I
suddenly get:
"USB Device Not Recognized" after plugging the TravelFlash 5in1 reader
into any usb port.
Some other usb peripherals work fine, only the PQI TravelFlash is not
recognized.
The system is a Dell Dimension 4400 running XP home.

Luckily I seem to have found the problem.
It appears that the MultiLINX driver installed by the Xilinx Free ISE
WebPACK 5.1i is not innocent.

After removing:
1. mlnxfltr.sys & mltlnx.sys from c:\windows\system32\drivers
2. rebooting
3. uninstalling the USB root hubs (there are two in a Dell Dimension
4400)
4. rebooting

I can again read my flash cards :-)

Have a good day,
Berni.
