Here's mine: 
uhci_hcd 0000:00:07.2: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1
Controller

Well ...

If you could try on such a thing, you could at least nail the problem
down to some controller driver issue. I'm really no expert with this,
so I suggest to also ask on the linux-usb lists:

Ah, okay. I have similar, even worse problems, with a Contour Shuttle
HID controller, which is totally non-functional on my VIA-board, but 
works fine on my intel laptop. It did not help to just use a
4-hub-USB-controller in between the VIA-controller and the Shuttle. 

All my other USB devices ranging from Soundcards to Webcams work fine,
though.

Ciao
