Hey,
So I'm running Ubuntu Hoarty on a Presario R3160US. I just compiled a custom kernel to get my touchpad scrolling working, so i'm at the very latest linux- revision that ubuntu offers in its repositories (that's 2.6.11).

A few weeks ago I bought this USB Mouse made by BenQ, and its never worked. I've done some investigating in the last couple days, and the system doesn't seem to find the mouse. I've checked lsusb and /var/log/messages and nothing shows up when i put in the receiver. Also, I tried plugging in my Logitec Key/Mouse set from my desktop (also running Ubuntu, but working fine) -- The receiver didn't get any power at all. Bizarrely, my USB flash drives work fine in all 3 ports.

Any Ideas?
