ATmega8U2 usb-serial firmware doesn't work at 300 (UBBR overflows) #542

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago

The ATmega8U2 firmware overflows UBBR at 300 baud because it sets the U2X bit, 
yielding a setting that overflows the 12-bits.  This was masked previously 
because the Arduino core contained the same bug: (issue #522).  I'm fixing that 
bug, though, so we should fix the firmware too.
