[avrdude-dev] [bug #43268] usb_drain() call causes LUFA AVR-ISP MKII Code to Fail

[Colin O Flynn]

Follow-up Comment #2, bug #43268 (project avrdude):

Have now added a hex-file for testing with RZRAVEN USB Stick. There is no IO
pins connected, so you can't program a real AVR. I don't even know where the
IO pins are routed. It also doesn't route the LEDs or anything so they don't
turn on. You can basically just confirm with dmesg it appears as expected.

You can run a command with -F to fake a read, but it will always be garbage. 

I've confirmed the hex file does work as expected. Although now on one of my
systems it works as expected (almost, just errors out once). Although on
another computer you get this, which is the bug being triggered:

address@hidden colin]# avrdude -P usb -p m328p -c avrisp2

avrdude: stk500v2_recv_mk2: error in USB receive
avrdude: stk500v2_recv_mk2: error in USB receive
avrdude: stk500v2_recv_mk2: error in USB receive
avrdude: stk500v2_recv_mk2: error in USB receive
avrdude: stk500v2_recv_mk2: error in USB receive
^C

i.e. you get that 'error in USB receive' in a loop and nothing else. It's
based on the latest release of LUFA (140302).
