Ahh thanks!
As I said in my first posting, I have never previously used the card
reader in all the time I have owened the Dell PC. I actually can't
remember exactly when I bought the PC (which suggests that it was probably
more than 3 years ago) so I guess that is the answer.
I have tried googling the information that lsusb gave me:
TEAC Corp. All-In-One Multi-Card Reader ID 413c:2003 Dell Computer Corp
But I have not yet been able to find anything definative.
Thanks for pointing me in the right direction. I guess I have two choices
the next time I need to write the disk image for the Pi: 1) buy an
external card reader or 2) keep using my work windows laptop (strangely,
also a Dell and also >3 years old - But I guess it is simply a different
type of card reader).
Thanks again.
Mark
