You can try turning on the USB Mass Storage verbose debugging option
in the kernel configuration (CONFIG_USB_STORAGE_DEBUG). That will add

Thank you for the advice, I will try to do so and post the results. But
it may take some time, please be patient ;-)

I finally managed to switch on debugging for usb-storage. The result was
interesting: No more errors for the Mitsumi FA404M card reader. After a longer
testing period I got an error for the TEAC FD-CR7.
After taking a deeper look to my kernel configuration, I found
CONFIG_USB_STORAGE_RW_DETECT set to NO. I assume this is not default, and help
text for this item looks to me like it could create original error.
Before turning on verbose debugging I used the precompiled 2.6.8 kernel from
Debian 3.1 Sarge. At that time I got a SCSI sense error on both devices.
Now I am using a self compiled kernel 2.6.8 from the Debian kernel package. I
There's no point trying to debug or fix a 2.6.8 kernel. You should start
using a recent kernel, like 2.6.14.

Alan,
you are absolutely right. I am sorry to have taken your time. I will do all
tests again with Kernel 2.1.14. If there are errors again, I will post them on
this mailing list.
