Follow-up Comment #2, bug #12622 (project avrdude):
I am having the exact same problem. I have tried 5.0BETA as well
as 5.0 with
no luck. In 5.0 I tried changing timeout.tv_usec as mentioned
above but saw
no difference after recompiling.
A few important differences, I am using Darwin 10.4.2 and a keyspan
USB <->
Serial adapter.
After typing in a standard avrdude command such as:
avrdude -p m163 -P /dev/tty.USA19H1b1P1.1 -c stk500
the terminal simply hangs. One interesting note, when I unplug the
usb cable
for the adapter, instantly I recieve the following error:
avrdude: ser_open(): can't open device "/dev/tty.USA19H1b1P1.1":
