Hi,
attached is a fresh US-122L linux(test-)driver.
If everything is installed on top a kernel 2.6.25-rc5 and
alsa-lib 1.0.16, everything works, erm at least here.
Without the ehci patch, it still works when connected to the uhci-hcd.
(Maybe the ehci-patch makes it into .26)
alsa-lib < 1.0.16 lets the plugin misbehave.
PCM access needs an ~/.asoundrc containing whats in .asoundrc.
Its established by patching/compiling/installing alsa-plugins.
You need to adjust the path to the kernel's sound/usb/usx2y/usb_stream.h
Only S24_3LE, 2 channels interleaved, 2 periods is supported.
The userspace pcm devicename then is forexample "usb_stream:1"
(To let alsa convert to other formats, use forexample "plug:usb_stream:1")
Tested with aplay, arecord, amidi & jackd using alsa driver.
Propably doesn't do 32bit PCM access on x86_64, tested on x86_64 only.
