Me no previous experience of card readers. Have Type One Compact Flash card to upload its contents from camera to XP pc as camera maker's software now corrupt so bought a Konig USB2 reader. This is self-energized from the bus & it lights up OK. Stated to be XP compatible.
But it won't read a Fuji 256MB card. Same pin configuration, no pins bent, card inserts perfectly. Another card (4GB) also failed. Sequence of connecting USB2 cable, inserting card, opening E-drive, all that played with to no effect. Yes, E-drive indeed appears when I open My Computer. Different USB2 ports tried.
No instructions supplied with brandnew reader as presumably all is self-evident. Plug&play and no drivers required? What am I doing wrong? Is it a dud?
