Hello everyone,

My laptop has been in reparation for a while and I just got it back now, so I have been out of sync with any update on the snd-usb module, the support of the M-Audio Fast Track Ultra, and I now need to re-setup my laptop.

As far as I can see, the kernel 3.2.5 doesn't have the update of Alsa 1.0.25, so the first thing I did was to compile those two separately (compile first the kernel without any sound support, then compile and install 1.0.25), but the midi was then not working on the M-Audio FTU, the Roland UA-25Ex and my E-Mu USB keyboard. All modules are probed, no messages in dmesg, but jack doesn't see any alsa midi driver. In addition, I cannot make out if Daniel's changes are part of this release of Alsa!

My next step was to get a git version of the kernel, add Takashi's branch and Daniel's one on top of it (process I used to do 2 months ago), but I get a conflicting error when pulling/merging Daniel's patch, so I guess it is not in sync with the latest kernel anymore...

So my questions are:

• Did I do something wrong with the kernel 3.2.5/alsa 1.0.25 that

broke the USB Midi or is it a bug? I ran through the mailing list but couldn't see anything mentionned about USB Midi. As far as I can tell, I have all the necessary modules.

• What is the status of Daniel's work on the snd-usb module? Again I

ran through the changelog of alsa 1.0.25 but couldn't make out if it was integrated or not.

Sorry for the silence on this topic. I've been distracted by work that isn't even remotely kernel related during the last weeks, so I lost track on this. I'll catch up again soon, and review the reports from around christmas last year, rebase the series and resubmit.

Again, sorry for the delay.

Daniel
