Here is a post i made over on xda-developers
i successfully got into adb in recovery mode fairly easily on my ubuntu 10.4 laptop using the following method-
this should also work for a linux live boot from a usb flash drive
in one terminal tail and follow log messages
~$ tail -f /var/log/messages
in another terminal run the loop
then
1. plugin usb and keep it plugged in
2. remove battery, eject sd card.
3. put battery in
4. press vol- and power
5. after around 6 seconds, your terminal with the log will show something like "new high speed USB..."
6. press vol- to select recovery
7. press the power button
8. IMPORTANT- as soon as you see a new log entry (something like "USB disconnect"), pop in the sd card
check your loop terminal for adb. if it doesn't work, repeat at step 2
hope this may be helpful to some
