Hello, 

This is to make Roland UA33 (Tri-Capture) work on 15-RELEASE.

3 files needs to be patched and then kernel rebuilt and installed.

These are the files and changes. I will add 3 patch files.

Code /usr/src/sys/dev/usb/usbdevs:
product ROLAND UA33             0x0132  UA-33 Audio I/F

Code /usr/src/sys/dev/usb/quirk/usb_quirk.c:
USB_QUIRK(ROLAND, UA33, UQ_AU_VENDOR_CLASS),

Code/usr/src/sys/dev/sound/usb/uaudio.c:
if (uaa->info.idVendor == 0x0582 && uaa->info.idProduct== 0x0132) return
(BUS_PROBE_GENERIC);

And of course make buildkernel and remember to make installkernel as well.

This was solved with input from the usb mailing list and from the forum.

/Roger
