Details:

Conditions: 
Linux Mint 17
avrdude V 6.1
Buspirate V3 
Attiny 10 with 5V
MOSI of Buspirate via 1k to MISO

MISO of Buspirate to TPI data
CLK of Buspirate to TPI clk
CS of Buspirate to TPI reset

If I send the command:
> avrdude -p t10 -P /dev/ttyUSB0 -c buspirate_bb -n -U fuse:r:-:h
then I will become a empty answer:

Attempting to initiate BusPirate bitbang binary mode...
BusPirate binmode version: 1

avrdude done.  Thank you.

Writing a fuse doesn't work, too.


If I go in the terminal mode of the avrdude then reading and writing of the
fuses works well.
