Next time I will write it down.

I could not find either of these in the SW81 modules (scsi).  Do I 
actually need them if I use usb.s kernel instead of usb.i kernel?

usbcore
usb-uhci  (which segfaults with SW71 insmod)
usb-storage
sd_mod  (or do this one at any other time)

Is this correct, if I use a kernel where scsi support is built in?

Yes, BL2 with SW81 kernel.  Should I try SW81 insmod if I have the 
dependencies for it?  (I have glibc 2.2.5 already).

Have you actually used USB with BL and SW81 kernel?

I know, but that was an example of how to use USB in linux.

I will try again some time this week.  I am supposed to be doing a large 
paid job first.  We just spent all day 'fixing' three floppy drives by 
discovering a whole box of floppy disks had bad sectors.  I can't check 
the drives in linux because they are 360K and don't work in linux even 
with the correct /dev .  (And I don't think floppymeter even has a setting 
for them).

Another approach is to make a 5V power supply for the camera and download 
for 2 hours via the serial cable.
