| | Hi Andrew,
| |
| | I suppose you tried the standard-branch of v4l, didn't you?
| | That one also caused the same problems on my side.
| |
| | Try this one instead:
| | hg clone http://linuxtv.org/hg/~pascoe/xc-test/
|
| Yeah I was using the standard branch and tried the xc-test branch after
| I emailed :) It started working with Chris' branch but now I'm having
| troubles with the USB device on the card. This is what I'm getting in
dmesg:
|
| ...

|
| If I modprobe the drivers (tuner-xc2028, zl10353 and dvb-usb-cxusb) in
| nothing happens, dmesg just says that a new interface has been loaded -
| no hardware initialisation messages or anything.

That's actually wrong, here one of the tuners accepted address 6 and I
could load the frontend for it. Not sure why but it seems that
occasionally one of the tuners will work, other times neither of them,
and as I said before I did have both of them working at one stage - it
seems pretty random :(

I had a look at the FAQ at http://www.linux-usb.org/ and found that my
problem's described there as well. I tried the relevant solutions (bios
update, rmmod/modprobe uhci-hcd) but none of them have worked.

It doesn't look very
| promising and it happens every boot since I got it working with Chris'
| drivers... not sure if it's correlated :( I've read the errors are
| something to do with the device getting suspended so I set noapic and
| acpi=off but that didn't help either :/ I'll chuck the card in a windows
| box and see what happens, see if that can kickstart it or something.
| Anything else I should try?

| |
| | That helped removing the segfault.
| |
| |
| | Hope this helps.
