I bought a multi card reader (external USB) some time ago for use with
CF cards which I was using at the time. I have recently begun using
SD cards and the first ones were 16MB and 1GB SD.
The 16MB has always been recognised immediately via the card reader
and kubuntu (6.06, 6.10, 7.04) but the 1GB cards are only recognised
intermittently. In fact I had one replaced at the retail shop. The
replacement did not get recognised either(!)
I now have additional 2GB sd cards and again they are sometimes
recognised, but mostly not.
Same happens in 'doze XP, intermittent and unpredictable. Sigh.
I sort of conclude that the card reader is old technology and I need a
newer one, which hopefully will handle larger SD better. (?)
It is not a question about mounting the card, it is simply not seen as
a card device, although the card reader is shown ok in
The cards all work ok in their respective units - a camera and DAB
radios etc, and can be seen and downloaded via usb from their units,
but not (usually) from the card reader.
I would be very interested in comments - SD standards seem to be a bit
of a nightmare according to wikipedia.
Are you sure enough power's being supplied to the USB card reader? My
WD Passport HDD and 2GB pen drive won't get recognised on my laptop with
insufficient power, but my 256MB pen drive will.
Thanks, yes, one of the test machines is using an external powered usb
hub - I also tried into the usb card directly on this, and a second
