USB Rio 600 error: usbd_setup_pipe: failed to start endpoint, TIMEOUT

A little while back I reported that...

After attaching my Rio to my PC running 5.2.1-RELEASE-p3 and trying to
communicate, I found that the rioutil was giving the same error, but ran
ok as root, suggestion a simple permissions issue.

Changing permissions of /dev/urio0 , the user is able to talk to the Rio
as before on 5.x, however despite correct persmissions the same error
persists in 4.x.

Any suggestions are welcome.
