Follow-up Comment #1:
I'm not completely reluctant to accept the patch, but in
trying to reproduce the problem, I failed so far.
First, I picked an ATmega16, and clocked it externally down
to 100 kHz. Running AVRDUDE with the USBtinyISP and the
argument -B100 (resulting in a 10 kHz ISP clock) allowed me
to successfully connect to it.
Then, I picked an ATtiny45, and changed the low fuse to
0xe4, resulting in it being clocked from the 128 kHz watchdog
oscillator. Again, using -B100 gave me a success in
connecting.
Finally, I changed the low fuse of the 'tiny45 to 0x64, so
the 1:8 prescaler is active, resulting in a total CPU clock
of 16 kHz. Obviously, -B100 is still too fast now, but
-B1000 (1 kHz ISP clock) makes it work again.
Am I missing something?
