Re: [LAU] [PlanetCCRMA] edirol usb soundcards

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
