LUFA (USB Framework for AVRs) Relay Board doesn't work anymore
Last modified: 2011-05-13 14:23:22 UTC
LUFA board not detected if compiled with avr-binutils-2.21.
dmesg: usb 3-1: device descriptor read/64, error 2 (and several other similar errors).
expected: usb 3-1: New USB device found, idVendor=03eb, idProduct=2ff9
It seems to be a regression: it worked fine with binutils-2.20, but fails with version 2.21.
It was reported that SRAM start offset seems to be
incorrect (0x60 in the new and 0x100 in the older version).
