Do you have a firewall and/or any other security software? If yes, try
temporarily disabling it and see if that resolves the issue. If not, I can
only suggest, concentrating your efforts and questions on the hardware
board. Also, have you considered the possibility the device is defective.?
If you've tried it on another system and it worked, maybe it's a conflict
between the device and something else on your system. That would require
trial an error disabling of other devices and/or software to try to find the
source of the issue.
I had a similar issue once with some software that was disabling my CD-RW
drive. I finally had to format the hard drive, install XP, install the
software for my CD-RW, then install everything else, drivers, applications
one by one until I found the source of the issue. Beyond that, the device
may simply not work, for whatever reason, on your setup. Perhaps a similar
device by a different manufacturer would work but for some reason, this
device by this manufacturer won't or doesn't.
