I managed to get my Fujifilm Finepix 40i to work with my Toshiba Laptop under Debian 2.2r3 by updating the kernel to 2.4.9, which also meant updating the following utils/modules, check that they are all recent versions:
The SCSI modules (they all changed completely for the 2.4.X series kernels) The mount utility USBDEVFS module/util (tells you what devices/drivers you have hooked up, under /proc/bus/usb)
I think that should do. There were a few other utils that needed to be upgraded to run my current kernel but they had nothing to to with the SCSI system or USB mass storage devices, or USB itself.
If I can get off of my bum and turn up to an ALUG meeting I might bring my laptop and camera if anyone has any trouble setting up their own stuff
