[SOLVED] 5 BTC - Noisy ttyUSB0 line?

SOLVED!

Seems like you are using the wrong kernel module for that device. Probably some generic usbserial thing instead of ftdi_sio.
The FTDI chip used in the BFL prepends two status bytes to the actual serial port data before transmitting them via USB, which result in that "2`" pattern. A correctly-working driver will interpret these bytes internally and filter them out from the data stream before passing it to the TTY.

Thank you!

This thread solved my problem as well.  I was using the generic USB drivers.  I switched to ftdi_sio and it solved it!

Thanks!
