I'm not sure this is the right mailing list for your question, since
it's more to do with USB then VDR.  However, maybe the source of your
problem is with the address bandwidth being used by your USB
harddrive, there isn't enough to handle everything, thus
bottlenecking.  That's just an idea but it's easily tested but moving
one of your devices to another USB hub, using a networked harddrive
for storage, or something like that.  If it magically works again,
then you know putting everything on the same USB hub is a problem.
