I guess there are too many variables, "-c arduino" caused me problems when I tried to load firmware into an AVR with the ISP tool (ArduinoISP sketch on an Uno) from a Linux host (I hope to try a Pi Zero soon) on the other hand stk500v1 is working fine.
@Ron,
I wrote the script and articles many years back, originally it was on Instructables and also in the forum in abbreviated format. But those were "windows" days and on XP. Later, the Hackster article, I was using Win8.1 but when Microsoft started the insane Windows 10 crap, I threw my MCSE title and Windows Anything into the round-file and moved 2 servers, 4 workstations, my backup development notebook, and two traveling HP Mini notebooks to Linux.
Since running Linux, I have not tested the individual components of the Windows batch script. There may be some issue in how Linux enumerates the USB that interferes with the documentation.
Thanks for mentioning your issue. Definitely something to make a note of ...
