Hi, The lack of TX buffers in that list (they're all RX buffers) means that the TX queue is empty. So, the "device timeout" is incorrect - the device didn't timeout, we just didn't queue any frames to the device but somehow the TX watchdog was set. Or, the watchdog wasn't cleared upon TX queue processing. I wonder why this is occuring. ;-) Adrian
