A warning to others, a "sudo apt install avrdude" did a just barely announced reboot of my machine, and it has taken me nomonally half an hour to restore everything that had x jerked out from under it. It killed x before it announced it on a text screen. The reboot was, shall we say, messy. No /var/run/locks were removed, so kmail had a cow when it was restarted. That was on my stretch system, it did not repeat on a buster install. But no TDE is in use there either. This device, a usb dongle labeled "USB ISP version 2.0" is apparently not well supported by avrdude. And unforch, the ATmel address in the man page is now re-directed to a Microchip site, ATmel I assume having since been bought by microchip, the product listing on that web page does not include the ATmega1284p, and while an option "-c usbtiny" gets a device listing that includes the ATmega1284p, this isn't a usbtiny. I am guessing from the instructions that this dongle has a memory area where the patches for marlin, the printers rs-274d driver, are kept, accessed and uploaded to the flash in the printers controller. But thats a WAG. I'll email the author by cc'ing, maybe he can help. Anybody have a better idea? I do have a $300 hp AIO I use as a graphics display for a Vector Network Analyser when I'm tuning an AM transmiter tower, but that is a home edition of W10, and the chances of that having a copy of progisp.exe are somewhere between none and dontbesilly.
