Windows 7 USB - Problems

Hi all,

sorry, but i did not find a Windows 7 forum.

We have the following Problem:

for some Clients USB is not working correctly
for Example:

we are Using Polycom CX 200 USB Phones. After some time there is no sound
but the PowerLED is on. Then i have to reinstert the usb adapter. then it is
working. That happens for 2 clients (we know just this 2) since the Upgrade
to Win 7.

Can we do somethink? Is there an Update? or somethink else?

Ciao
Pascal

Check the USB power options. Run the Windows 7 upgrade advisor.
