I stumbled into a quite simmilar problem as Rene Herman. So he asked me to mail to you. Here a short intro:

My VIA USB driver using EHCI is disconnecting my video
encoder device (Hauppauge PVRUSB2) after working for
about 10 minutes.

Details (including usb-debug output, lspci, lsusb, lsmdo) can be found at:

Any suggestions what to test/to do?

Just to make it clear -- the striking similarity is that he also has the IDE throughput drop; 34MB/s to 15MB/s in his case. No idea if his async schedule should be turning on and off with the USB PVR, but it seems very likely the same problem...

(hope I don't break the thread; replying through the gmane news gateway)

Rene.
