ATmega168 documentation uses word addressing, avrdude uses byte addressing

I was programming USBaspBootloader into a metaboard with an Atmel AVR ATmega168 microcontroller. I always got this error: usb 6-2: device descriptor read/64, error -71 … usb 6-2: device not accepting address 21, error -71 1.

First off, I tried connecting one working programmer to the other and see how it goes. Well, FreeBSD couldn’t recognize [...]
