I've started working on that, though I can't seem to make it work at all yet. I'll keep beating on that. Meanwhile I noticed that with kernel 3.15.4 I am getting log messages when the ftdi_sio input gets stuck, which I didn't seem to get previously when I was using 3.14.4. Whenever it happens I get two messages: Jul 12 18:32:44 p1 kernel: ftdi_sio ttyUSB0: usb_serial_generic_read_bulk_callback - urb stopped: -32 Jul 12 18:32:44 p1 kernel: ftdi_sio ttyUSB0: usb_serial_generic_read_bulk_callback - urb stopped: -32 Any idea what can cause a "urb stopped"?
