Don't forget to read NOTES.  Some devices are not intuitively obvious. 
You need SCSI to run a USB mass storage device even if you don't have a 
SCSI host adapter.

dmesg like the other fellow said.  There is one caveat.  If you have 
some obscure hardware it may not show in dmesg output because it was 
never built into GENERIC.  For this hardware you might look at the chips 
on the mainboard or in the hardware manual.  You the take the chip's 
identifier (for lack of a better word) and grep the kernel config files 
to find the right driver.

And oh yeah, you could use these docs:

But that's less adventurous.
