Hi Daniel,
thank you very much for your comments! I hope I fixed most of the points but I also have a few questions/comments:

Please use the define directly instead of introducing a new one.
I replaced it with:
#ifndef CONFIG_USB_DEBUG #define CONFIG_USB_DEBUG 0 #endif
As it can be undefined. I hope that's okay.
Your patch has a huge number of style issues, which scripts/checkpatch.pl will point you to. I got:
Interesting, I copied many issues from other modules. :) If fixed most of them except these:
WARNING: quoted string split across lines #310: FILE: sound/usb/bcd2000/bcd2000.c:254: + "bcd2000_midi_send(%p): usb_submit_urb() failed" + "ret=%d, len=%d\n", substream, ret, len);
WARNING: quoted string split across lines #392: FILE: sound/usb/bcd2000/bcd2000.c:336: + "bcd2000_init_device: usb_submit_urb() failed," + "ret=%d: ", ret);
I don't know how to avoid them, as all strings in one line would be longer than 80 characters.
/* determine the number of bytes we want to copy this time */
tocopy = min( 3 - bcd2k->midi_cmd_offset, length - (buf_offset - 1));
if (tocopy > 0) {
tocopy is unsigned char, so this check is always true, and the copy routine can overflow in case bcd2k->midi_cmd_offset < 3.
I don't understand your point here. It could be zero. But I changed it to a condition that checks if both offsets are within the length of the two involved buffers.
Please, no dead code. Remove those lines entirely if you don't need them.
Ah okay, I planned to reactive them with the audio part. But I removed them for now.
As far as I understood, I should repost the new patch as [PATCH v2]. I will check this evening if the device still works and send it to the list afterwards.
Thank you! Mario
