| 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:

...
usb usb8: configuration #1 chosen from 1 choice
hub 8-0:1.0: USB hub found
hub 8-0:1.0: 4 ports detected
usb 8-1: new high speed USB device using ehci_hcd and address 2
usb 8-1: device descriptor read/64, error -71
usb 8-1: device descriptor read/64, error -71
usb 8-1: new high speed USB device using ehci_hcd and address 3
usb 8-1: device descriptor read/64, error -71
usb 8-1: device descriptor read/64, error -71

DVB: registering frontend 0 (Philips TDA10046H DVB-T)...
usb 8-1: device not accepting address 4, error -71
tda1004x: setting up plls for 48MHz sampling clock
usb 8-1: new high speed USB device using ehci_hcd and address 5
usb 8-1: device not accepting address 5, error -71
usb 8-2: new high speed USB device using ehci_hcd and address 6
usb 8-2: configuration #1 chosen from 1 choice
...

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. 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?

Andrew
