Hi,
it has been reported that the 2.6.8 kernel has fixed the handling of
USB resets, so now it's possible to use a Linux firmware loader to get
these devices to work.
You can get the loader at <http://usb-midi-fw.sf.net/>.
Best regards,
Clemens

I'm running an AMD64 kernel in 64bits mode, if that makes any difference.

Please show the output when you add the -v parameter.

I'm running an AMD64 kernel in 64bits mode, if that makes any difference.
This looks as if I'm using a wrong data type in some structure
(probably usbdevfs_ctrltransfer).
Anyway, I just released a new version which should work in 32bit mode:
