You are right! I tried a different USB port and the device was recognized. 

My battle is now with me-tv. Its scan doesn't find anything. The scan 
program from v4l finds channels, but me-tv complains "There's an invalid 
channel record in the channels.conf file". If I put the v4l scan 
channels.conf in my .me-tv directory, me-tv complains that the file is 
not utf-8 encoded. Always another barrier. :-)

As Steve suggests, I'll start specific HVR-950Q threads for additional 
issues.
