Hi Marco,

I "played" a little bit with my problem and tried the latest source from the

I activated the debug options of all, I hope, relevant modules now and got a
more detailed kern.log.
Maybe some expert can help me and take look at it.
Interesting section:

BOOM -> Jun 1 23:16:14 vdr kernel: urb completition error -75.
Hmm?!
This logs aren't very helpful, but I find something interesting with
Wireshark and usbmon:
device -> host
URB type: URB_COMPLETE ('C')
URB transfer type: URB_BULK (3)
Endpoint: 0x83
Device: 13
Data: present (0)
URB status: Value too large for defined data type (-EOVERFLOW) (-75)
URB length [bytes]: 39424
Data length [bytes]: 39424
after this URB I get a "URB transfer type: URB_INTERRUPT (1)" and all goes
to hell.
Its also interesting that the URB+data length in the failure package is
39424 but "URB length [bytes]: 39480" in every package before that.
Definitely interesting. This is a known issue for the dib0700 device,
which happens on some USB host controllers. Actually which one do you use?
As I know this device works without problems under linux for other people,
so I'm wondering why. I searched but found nothing about such a problem.
Yeah, but are they using 2.6.29?
In fact, since 2 days I'm having the T5 Terratec device, which seems to be
similar to your device, I'm going to try it soon. To experience whether
there are similar problems.
Do you connect the device directly to the PC or is there an extension
cable or another USB hub in between?
Patrick.
