Ive managed to get it to generate the /dev/ttyUSB0 device now, by adding the following udev rule;
SYSFS{idProduct}=="6014", SYSFS{idVendor}=="0403", RUN+="/sbin/modprobe ftdi_sio product=0x6014 vendor=0x0403"
but... i now get the following;
BFL 0: 1107951616.0C | REST / 0.0Mh/s | A:1 R:0 HW:0 U:9.96/m
[2012-07-21 03:01:02] BFL0: Hit thermal cutoff limit, disabling!
[2012-07-21 03:01:05] BFL0: Hit thermal cutoff limit, disabling!
im sure if it was that hot, it wouldve gone into meltdown by now!
