I searched the forum and saw this issue come up several times, but my issue seems to be different so I am starting a new topic.
I've been using an RBBB arduino clone on a macbook with Arduino 0018, it is powered by the USB port. While doing some experiments the laptop shut down abruptly (I don't think I shorted anything). Since then when trying to upload a sketch I get the "programmer is not responding" error.
I tried additional atmega chips and pulled a diecimilia out of another project, they all have the same error now. So it doesn't appear to be the board.
It seems that I did some damage to the USB port... but am still able sync/update my phone via USB so it seems like the USB ports may be ok.
I updated to Arduino 0022 and reinstalled the FTDI driver (did not uninstall the old one, not sure how), same error.
Has anyone seen anything like this?
