Hello
I'm trying to use dual DVB-T tuner based on ITE9135 tuner. I use Debian
kernel 3.5-trunk-686-pae. My motherboard is AsRock E350M1 (no USB3 ports).
Tuner is detected ok, see log at the end of post.
When I try to scan channels, bug happens:
Sep 11 17:16:31 wuwek kernel: [ 209.291329] ehci_hcd 0000:00:13.2:
force halt; handshake f821a024 00004000 00000000 -> -110
Sep 11 17:16:31 wuwek kernel: [ 209.291401] ehci_hcd 0000:00:13.2: HC
died; cleaning up
Sep 11 17:16:31 wuwek kernel: [ 209.291606] usb 2-3: USB disconnect,
device number 2
Sep 11 17:16:41 wuwek kernel: [ 219.312848] dvb-usb: error while
stopping stream.
Sep 11 17:16:41 wuwek kernel: [ 219.320585] dvb-usb: ITE 9135(9006)
Generic successfully deinitialized and disconnected.
After trying many ways I've read about problems with ehci on SB700 based
boards and switched off ehci via command
sh -c 'echo -n "0000:00:13.2" > unbind'
and now ehci bug doesn't happen. Of course I can see only one tuner and
in slower USB mode (see log at the end). But now I can scan succesfully
without any errors.
Of course it isn't acceptable fix for my problem. Drivers for ITE9135
seems ok, but there is a problem with ehci_hcd on my motherboard.
I would like to know what can I do to fix my problem.
