This fixes issues with M-Audio's Fast Track Ultra series:
- devices now work at 44100 and 88200 Hz
The descriptors already list these rates, so in theory, the existing code that sets UAC_EP_CS_ATTR_SAMPLE_RATE should already have enabled this. Didn't it? In other words, what is the difference in the explicitly specified audioformat?
(I have the suspicion that we don't actually need a AUDIO_FIXED_ENDPOINT quirk for these devices.)
- apparently, fixes some crashes, too
When do these crashes happen?
This is based on a patch posted by user 'dhubsith' on the M-Audio user forum.
If you don't have the exclusive copyright for the code in this patch, there needs to be a Signed-off-by line from him, too. OTOH, a table like this probably isn't copyrightable at all.
- USB_DEVICE(0x0763, 0x2080),
USB_DEVICE(0x0763, 0x2081),
...
This replaces the ID of the Ultra 8 ID with that of the Ultra 8R ...
USB_DEVICE(0x0763, 0x2081),
- .driver_info = ...
.driver_info = ...
... and this just changes the other 8R entry. So now the 8 doesn't have an entry.
