Hi,
The VG-99 is a guitar processor with a usb interface which offers
2x16bit 44100 pcm in and out streams in its basic usb mode, and
2x24bit 44100 in/out + midi in the advanced mode connection mode.
Basic mode works fine with usb snd driver, but the device isn't
recognised when set to advanced mode (this is done under USB on page 2
of the "system" config menu)
I've used the lsusb -v output (below) to guess at an addition to
sound/usb/quirks-table.h to try and get this working. On initial
(brief) testing, audio in/out at 24bits (as shown by jackd output) and
midi (out, at least) are all working.
I'll attach the quirk, and would be pleased if someone could look at
it, and the lsusb output, and fix up any deficiencies (it's purely
voodoo here :-D) and maybe get it or something like it into the
official source... please let me know if changes need to be tested.
Cheers,
- Pete.
