Hi,
If you're running Ubuntu, it's not that much work.
I had the same problem with the Boss ME-25, I did this:
- apt-cache search linux-rt
# pick the linux-image-xxx from that, linux-image-2.6.31-11-rt in my
case
- sudo apt-get build-dep linux-image-2.6.31-11-rt
- apt-get source linux-image-2.6.31-11-rt
# you'll get a directory linux-rt-2.6.31
- cd linux-rt-2.6.31
- find | grep usbquirks.h
# you'll see ./sound/usb/usbquirks.h, edit it
- dpkg-buildpackage -b -us
-uc -rfakeroot
# this runs for a while
- cd ..
- sudo dpkg -i
linux-image-2.6.31-11-rt_2.6.31-11.154_i386.deb
- # boot the new kernel

Sorry, that is not easy to explain and involves much work (that file is
part of the kernel source tree). I'll see if I can add this to my next
build of the rt kernel for Planet CCRMA.

For some reason, the driver has a quirk only for the MIDI interface of
the PCR-1 but not for the PCM interfaces.
Try adding the following entry to sound/usb/quirks-table.h or
usbquirks.h and then recompiling the driver:
{
USB_DEVICE(0x0582, 0x0064),
.driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) {
.vendor_name = "EDIROL",
.product_name = "PCR-1",
.ifnum = QUIRK_ANY_INTERFACE,
.type = QUIRK_COMPOSITE,
.data = "" struct snd_usb_audio_quirk[]) {
{
.ifnum = 1,
.type = QUIRK_AUDIO_STANDARD_INTERFACE
},
{
.ifnum = 2,
.type = QUIRK_AUDIO_STANDARD_INTERFACE
},
{
.ifnum = -1
}
}
}
},
