New devices with crystal oscillators still works fine with USB 2.0 ports on Windows 10 computers. It's worse for OSCCAL though -- if you store the tuning in EEPROM, you can at least unplu...

This seems to be a bigger deal than just osccal... I can't get any of the examples working in Windows 10 -- same exact hardware/firmware works fine in Windows 7, but completely fails in Windows 10 with "A request for the USB device descriptor failed.", and in device manager under VID/PID i...
