To be able to use USB I need to use the supplied 8 MHz oscillator of
the AVR board. According to atmel tables this does means that if I
configure USART for 115200 the baud rate error is -3,5 % (too
slow). This probably explains why I only got garbage data.

I started to capture the data by simply polling the input pin in a
tight loop (bit banging) and managed to decode

\x02\x12ADC:169470\n\r\x02\x02\x12gauging16947\n\r\x02\x02\x11\x00\n\x00\x10\x10\x05IQEXT:ADCEnd\x02

Any idea what those \x02's, \x11's and \x00's are for? Just decoding errors?

The raw data is at
http://iki.fi/lindi/openmoko/calypso-logger/bitbang3.out
and
http://iki.fi/lindi/openmoko/calypso-logger/decode-serial
is a quick'n'dirty decoder.
