I'm having some trouble trying to run the javax-usb-ri-linux package on a
fairly new linux (2.6.31.1). After manually mounting /proc/bus/usb I seem
to be hitting the same problem with both my client and the sample swing
client. Filesystem info and trace messages below:
i...@ubuntu:/proc/bus/usb$ ls -l ???/???

This seems to occur on the fir Pipe Request. In the swing client this is a
control message with length 256. In my client, this is an interrupt or
bulk message with length 64..
Any ideas?
