Hi list, not sure if this has been reported already, but today I was able to connect an RME Fireface UFX in class compliant mode via USB to my Debian box and got 22 Channels (the limit in RME's class compliant mode) of output working (was not able to verify inputs due to a lack of real-world input sources) with Pure Data and ALSA's OSS emulation, as well as with jack. Most likely it does not make sense to purchase such an exquisite audio interface for use with linux, as the mixing application will not be accessible from software, and with it most DSP processing power in RME's on-board mixer. But in case your institution/department chair/infrastructure management decided to buy such a thing, and you see it sitting unused on a shelf in someone's office, i thought it might be nice to know you can get at least 22 I/O with it on a standard Debian testing box via USB 2.0 best, Peter
