I've tried a 256 MB SD card and the 4 GB compact flash card, both of
which work fine, so I was assuming it was a problem with SD cards above
a certain capacity, possibly 1 GB since this is what fdisk tells me my 2
GB card is.
I'll see if I can get hold of some other cards to test.
Here's the output of lsusb:
