Comment 4 for bug 256492

I have installed the kernel 2.6.27-3-generic and the issue remains. The bug appears when dvb-usb-nova-t-usb2 and modules are loaded and I plug another USB2 device (I have tried with a WIFI dongle, a DVD drive, a harddisk and a memory stick) on the same USB root controller and I use it (read files or connect to a WIFI network).

There are lots of errors like these in the dmesg output:

[298862.248639] dvb-usb: bulk message failed: -22 (6/-169911008)
[298862.248646] dvb-usb: bulk message failed: -22 (6/-169911008)
[298862.248652] dvb-usb: bulk message failed: -22 (6/-169910840)
[298862.257432] dvb-usb: bulk message failed: -22 (6/-1072526540)
[298862.257448] dvb-usb: bulk message failed: -22 (6/-1072526540)

[298862.257466] dvb-usb: bulk message failed: -22 (6/-137609952)

In this state all the USB peripherals are unusable (including USB 1.1 ones). When I unplug the DVB tuner, the system is restored.

In my previous computer (a powerpc MAC mini) the DVB tuner works flawlessly. I've tried also in a Dell lnspiron 6400 (Intel Core 2 duo) and works okay.
