I read David's responses out of chronological order.  Apparently he is 
offering to build custom 2.4.31 kernels if needed.  I will try the basic 
one first (with no modules required) and hope it works as well as the SW91 
live CD did.  There is really no need to have one kernel that does 
everything including download from USB cameras, unless you are a 
professional photographer.  Switching to a 2.4.31 kernel would require 
duplicating a lot of modules.

I could not get SW81 usb-storage to work either but it could be insmod. 
Something about resets.

Did that 'insert properly'?

I will be delighted to try this out as soon as we get the computers put 
back together some time this week.  Still shuffling hard drives, RAM, 
cpus, and video cards around in my two computers with USB ports.

Thanks!  Sindi
