Due to OpenWRT not supporting the BlueFuzzies, I'm moving over to RPi - really don't want to be running a PC just to run a pair of Blues...
The endian issues with the BigPictureMining driver should be fixed in 3.5.2+ - do you still have problems on OpenWrt?
I didn't try it with 3.6.0 - I'll try it later and see how it goes.
Edit: 3.5.2 is showing as the latest on OpenWRT...
