Hallo,
here's the second one of my current USB bulk messages:
I'm trying to get the Edirol UA-1X to work, which I didn't find in the
list of supported devices yet, so maybe this has some interesting
information for driver developers.
Plugging in the device into a 2.6.1 kernel with ALSA cvs from
yesterday, gives these log-messages:
Feb 1 17:16:21 fliwatut kernel: hub 1-0:1.0: new USB device on port 1, assigned
address 2
Feb 1 17:16:22 fliwatut usb.agent[1429]: ... no modules for USB product 8bb/2902/100
Feb 1 17:16:22 fliwatut usb.agent[1445]: ... no modules for USB product 8bb/2902/100
Feb 1 17:16:22 fliwatut usb.agent[1461]: kernel driver hid already loaded
Feb 1 17:16:22 fliwatut kernel: drivers/usb/input/hid-core.c: ctrl urb status -75
received
Feb 1 17:16:27 fliwatut kernel: usb 1-1: control timeout on ep0out
After that /proc/asound/cards recognizes (?) it like this (card 0 not
shown):
1 [default ]: USB-Audio - USB Audio CODEC
Burr-Brown from TI USB Audio CODEC at usb-0000:00:07.2-1
which is a bit strange, because "default" should be a reserved id,
shouldn't it?
If I try to play over hw:1 or plughw:1 with aplay, or if I try to open
alsamixer on it or if I try to do anything involving the card, the
relevant process hangs forever. Even the alsasound init script hangs
when it tries to store the mixer settings on reboot, so I have to use
the Magic Sysreq keys to actually be able to reboot. Otherwise the
machine works fine, I still can use the first soundcard.
Below's the usual lsusb -vv output, but to my eyes this looks as if the
Edirol device isn't among the displayed settings. Feel free to ask for
more debugging info. Any chances to get this to work?
