yes, lsusb. That's what I get for typing too fast. :-/
Can't say much about the Thinkgeek models (I'll have to read about those as I got mine new from a secondhand store), 
Looking more and more like cable or unit has an issue.  I'd start with the cable, but a full return might not hurt.
Mine shows this from lsusb:

			Can you post the results of an "lssub" under Linux?  (if the command doesn't work try it as root or 'sudo lssub' and use your user password)
There is an option in the settings menu that says USB Host On|Off.  what is yours set to?  I tried both and it didnt' seem to matter under either OS.
		
		
	 
USB Host On|Off option didn't do anything. I think that has to do with usb networking but not sure.
there was no command lssub but if you meant command lsusb it returned:

I hear people have problems with the ones purchased from Think Geek (which is where I got mine) but I think I might try to just exchange it and see if getting a new unit helps.
I'll wait to hear back from this board before doing that though
