USBasp -P option failing

[JanHenrik]

Hey! 

I encountered a problem with a multiple USBasp programmer setup and I would 
like to ask if this is known/if there is a known fix to it. I looked though the 
bug-reports and searched the internet, however this seems to be a either rather 
unknown problem or usecase.

The AVRdude documentation states, that multiple USBasp programmers can (only) 
be distinguished by their physical USB-Bus connection via the '-P' option (e.g. 
in my case, Linux, '-P usb:001:095', lsusb shows two programmers located at Bus 
001 and device 095 and 094). However this does not work, I can write pretty 
much anything after '-P' (yes even '-P Babelfish' works :D), the last connected 
programmer is always chosen. Is this a known Issue and is there a fix for it?

I am using two (later more) usbasp-clones (FASTUSBasp based), connected to the 
same USB-Hub, running the following command: 'avrdude -p m328p -c usbasp-clone 
-P usb:001:095 -v -B 4 -U flash:w:firmware.hex'


Thank you in advance!
