I’m trying to get the Mutable environment to recognize my USB to flash a Grids. I’m using the export commands, but I’m having trouble finding my USB serial for my AVRISPmkII for the export PROGRAMMER_PORT command, since there isn’t a tty.usbserial-xxxxxxxx file in my linux distro. I’ve tried lsusb -v to get the serial but it doesn’t show up. I’ve tried routing it to the bus/003/007 since the programmer shows up in lsusb in that order, but it still won’t recognize it. Am I doing something wrong altogether, or looking in the wrong places?
