Re: Problem with 2GB card using USB SD card reader

Hi Matthew et al.,

I've gotten around to creating a log of the verbose debug output when
I attach the card reader with an SD card inserted. This is a multi
card reader with 4 slots for different media type, the other three of
which are empty.

I've placed the log here:

Cheers,

Jason
