Thanks to both of you for the detective work.  Please test the
attached patch series against a 3.2.y kernel, for example following
the instructions from [1].

Hope that helps,
Jonathan

Subject: usb: add USB_QUIRK_RESET_RESUME for M-Audio 49

Some USB MIDI keyboards fail to operate after a USB autosuspend.  The
device is recognized by ALSA, but no events are received and the
device goes quiet.

        $ amidi -l
        Dir Device    Name
        IO  hw:1,0,0  Oxygen 49 MIDI 1
        $ amidi -p hw:1,0,0 -d
        <... play some notes ...>
        ^C
        0 bytes read

A workaround is to disable USB autosuspend for these devices by
putting AUTOSUSPEND_USBID_BLACKLIST="0763:2027" in
/etc/laptop-mode/conf.d/usb-autosuspend.conf.  In the spirit of commit
166cb70e97bd ("usb: add USB_QUIRK_RESET_RESUME for M-Audio 88es"),
reset the device on resume so this workaround is not needed any more.
