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,

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 ...>

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.
