I've had the same problem from the moment I bought my BCR 12 months ago:

For about 4 months I thought it was due to a messed-up driver
installation under Windows: the standard "USB Audio" versus the
Behringer-supplied 1.1.1.0, 1.1.1.1 and 1.2.1.3; you know the type of
problem...

What often happened was this:
I started my own BC Manager (which I was developing), then the BCR
would stop sending data after about a minute. Then I exited BC
Manager, and when I restarted it, BC Manager immediately reported
"Undefined external error".
(The source of this error message was the Windows MMSystem MIDI layer,
responding to BC Manager's attempt at connecting to the BCR's
USB-based MIDI device; I've noticed that other software (Sonar, Reason
etc.) may or may not produce similar messages.)
What I then often did was reinstall the USB driver (I can't remember
if this procedure involved leaving the BCR switched on, or re-powering
it): then the USB connection would often work correctly for the rest
of the day.
So you can understand why all those months I thought that the USB
driver was the cause.

However, 8 months ago I bought a BCF, and over the next few months I
slowly realized that the BCF NEVER had this problem. Finally I spent
at least a full week trying everything I could (roughly the same list
you've mentioned). In the end I came to the same conclusion as you:
the USB controller on my BCR is defective, and has been since I bought it.

So the reverse of Martin's and my problem on the BCR ?!
Very intriguing.

I'm planning on going back to the shop with my BCR (I still have about
11 monhts of warranty), once I can find the time to do so, hopefully
within about a month. I'll let you all know what comes out of this.

Mark.
