Lexar Media - Piece o' Shite!
Don't bother buying the Lexar Media USB2.0 Multi-Card reader. It's a load of old bollox.
Seems to work OK with SD cards, but Compact Flash - forget it. I don't know, maybe it's the San Disk 512Meg CF card that's to blame, but I doubt it. That thing seems happy inside my Zaurus.
