Hi all!

When i insert a USB 2.0 device i get the following errors:

[   93.680054] usb 2-1: new full speed USB device using uhci_hcd and address
[   93.843342] usb 2-1: configuration #1 chosen from 1 choice

(it lacks a hardware PID filter)
[   94.317471] dvb-usb: E3C EC168 DVB-T USB2.0 reference design error while

I've seen this message many times when searching the internet for a
solution, but i haven't found the solution yet.

Does anybody know how to solve this?

This is Ubuntu on an EeePC 701. And yes, this machine does have
USB 2.0 ports.
