 Has anyone successfully programmed an R3k module using the clrfu and a USB adapter? The manual says using USB is an option, but I can't get it work. I usually get error, "Error reading bytes". I can communicate with the Rabbit using a USB adapter, just not reprogram it.  Programming works fine using the serial port with the same set of cables. 
 

 Commandline: clrfu .\myfile.bin -s 4:115200 -cl .\coldload.bin -pb .\pilot.bin -v -vp- -usb+
 

 I'm using the adapter that Z-World used to recommend. I think it's Tripp-lite.
