I have a Sandisk 12-in-1 reader that works fine over USB with both of my Zaurii.
C-3100 (Cacko) / and C-3200 (pdaxii13)
When using this reader with my Zaurus, I have better luck using only one slot at a time.
In other words, if I have an SD card and a CF card plugged in at once, the SD card is detected first and the CF card goes un-detected. (Or the other way around).
The name is, "Sandisk" - "ImageMate" 12 in 1
and model number is, SDDR-89 V3
You can get these at Staples.http://www.staples.com/webapp/wcs/stores/s...9&cmArea=SEARCH
