I got this to work a few times over a month or so, but today when I connect it, the computer appears not to assign a port to it. USBtiny shows up in Device Manager, but I see no COM port assigned, and when I run avrdude, I get the following error (which seems to have plagued a few other users):
avrdude.exe: ser_open(): can't open device "\\.\com[anything i try]": The system cannot find the file specified.I’ve tried multiple ports. Anyone know what I can do? Should I buy an Atmel programmer and give up on this device?
