I tried http://git.plugable.com/webdav/udlfb with which seemed to work for a
while with this test loop:

while true; do
  dd if=/dev/zero | tr '\0' $(($RANDOM % 256)) > /dev/fb1 2>/dev/null
  sleep .5
  shuf -i1-1000000 > /dev/fb1 2>/dev/null
  sleep .5

But after a few minutes output would stop,
and this started appearing in the logs:

udlfb: wait for urb interrupted: ffffffc2 available: 0

Reloading the module got things going again.

The device is a DL-195 attached to a 1600x1200 monitor.

Any ideas?
