Hi,
As in the title, I plugged in the BF via USB this morning (without power cable) but the unit didn't initialise. On the top of the unit the 'in' LED flashes, and the second LED up on the Right hand side flashes too.

I've updated the new driver on the mac side, but cannot on Windows as the unit is not recognised in the device manager.

Any ideas?
Thanks in advance,
Matthew
