I have a SanDisk Cruzer reader, and I have a 32MB, 128MB and 512MB
successfully. In fact, I have a encrypted loopback ext2 filesystem created
on the 32MB.

A couple of questions. Do you compile your own kernel? I have been able to
mount it on a system I built last week with the base install and a limited
number of debs (its going to be a firewall). This box, at the moment, only
has a default kernel installed.

plug it in? Do you have other USB devices and do they work?
You need, at a minimum, the following enabled in your kernel:
CONFIG_SCSI
CONFIG_BLK_DEV_SD
CONFIG_USB
CONFIG_USB_DEVICEFS
CONFIG_USB_EHCI_HCD (for USB 2.0)
CONFIG_USB_OHCI_HCD and/or CONFIG_USB_UHCI_HCD (USB 1.1)
CONFIG_USB_STORAGE
CONFIG_VFAT_FS
I believe these are all the kernel parameters that need to be set (either
module or inline should work). When I plugged the card into the
firewall-to-be, I got the following:
