Help with EDIROL UA-101 midi not recognized on kernel / UA101 improvements

Hi alsa-devel,

I have an old edirol interface (ua-101) that is still kicking (8 channel I/O in a small package)

The problem is that recently (I don't know from what kernel) the midi is not recognized anymore. Also I would like to implement an application to control the internal mixer.

Can someone help me out/point me in the right direction where to start?Or help me with this? I never debugged an USB driver before.

Thank you Nicola Lunghi
