get usb sound support in varkey's rootfs

Did you execute the command depmod -a? Do you still have the other messages?

yes depmod -a same error messages

if i do modprobe afterwards. depmod -a doesn;t do anything itself
nothing in dmesg

Depmod -a just registers available kernel modules. Reboot afterwards and check with dmesg if pci messages are still there and with lsmod which modules were loaded.

after boot this is what partly dmesg output looks like.

I think that the driver which is contained in the kernel doesn't work (with your device). At least something seams to be wrong. If you compare it to my lsmod listing below you can see that modules are missing which depend from snd_page_alloc and this is the module which produces the pci... error messages in your case.

okay. i'll figure something else out for my pogoplug. it can be used as something else than audio streamer.

What programs did you plan to install on the device to serve as an audio streamer?

mpd.

and now got a rapsberry pi running MPD. and it works great. It even recognizes my USB DAC directly. No need to use the Terratec USB soundcard.
