Microsoft Broadband Network MN-510

Hi,
I recently purchased a MSBN MN-510 Wireless USB adaptet
for my desktop... I'm using a Windows 2000 operating
system. I'm trying to install MSBN without any luck... i
follow all instructions and the system doesn't detect the
Adapter. Everytime i take it out and put it back in the
USB slot, the green power light lights up for a second and
then disapears. The help section just says that the USB
has to be powered. Have any of you encountered this
problem? Or know of anyone who has? Appreciate the help.

Regards,

Quinton.
