Tascam US428 (usx2yloader-related scripts) broken in HH (and possibly II too)

Binary package hint: alsa-firmware-loaders

The /lib/udev/tascam_fw script (in alsa-firmware-loaders) seem to be expecting a /proc/bus/usb/ style path, which doesn't seem to work properly. The solution I've used was to replace "proc" with "dev". I'm attaching a modified version (which works for me, but it's ugly/proof of concept quality).

Note: I'm not sure if it's *all* that is needed to get US428 to work - I've been fiddling with various things for some time before getting it to work. But it doesn't seem to function without that change.
