Thanks. I'll check that out.  I know at least in the usbview program, it
shows the interface as an hid device.  I'll try running skype as root to
double-check that it's not a user-permission problem, like you mentioned.

I know at least on the windows side, it's detected as a "composite device"
and there's just a piece of software (from linksys) that makes it
communicate (and actually work) with skype.
