Hello John,

I added support for that device.  A couple of questions:

1.  Are you sure the port on the PC supports USB 2.0?

2.  Which application are you using to test with?

3.  Are you doing anything with suspend/resume on the PC?

4.  Are you plugged directly into the USB port, or are you using any
sort of USB extension cable?

Once I know the answers to the above questions, I will see what I can
figure out.

Regards,

Devin
