 > Reproduced the problem on a B4 with JTAG.  With the debugger we could
 see that the firmware is in a valid state waiting to receive a command on
 ep2 to resume USB communication.  The command is never received because
 the host controller reports a transaction error.  According to the
 [http://www.intel.com/technology/usb/download/ehci-r10.pdf EHCI Spec] the
 only causes for transaction errors are CRC, PID (Packet ID) or Timeout
 errors.

 This morning, we confirmed that was no error on the USB bus using the
 LeCroy USB analyzer as well.
 So, essentially, although these errors on coming up from the host, there
 is nothing even close to being fishy that we see on the USB bus. This is
 the point where we thought that it would be a good idea to involve AMD
 experts.
