Hi Dan,
Thanks for your fast reply!
Here's the output from /var/log/messages when I connect the new device...
Jun 27 18:17:50 gilmour kernel: [ 3537.347832] usb 1-3: new full speed USB

driver
Then I rmmod usbhid, so javax-usb can claim the interface, and this is the
message i get:

Seems to be pretty normal, huh? After this, no more messages, not even
during javax-usb initialization...
I can see that javax-usb claims the device, it just doesn't control it. This
is the complete output from MouseDriver.java:
Found 1 HID-type interfaces.
Found mouse by SubClass/Protocol
Found mouse by Usage Page/Usage ID
Found HID mouse.
Driving HID mouse, move mouse to see movement events.
Press Enter when done.
Unable to submit data buffer to HID mouse : Error submitting IRP : Error 62
Hope this can give you a hint of what the problem is... I'll now take a look
at the kernel source (ouch)...
Thanks!
