yes- i have found that 200dpi lineart is the largest letter-sized scan you 
can do at fullspeed with usb 1.x. At resolutions/depths higher than that, 
you end up waiting for scan data after the paper has left the scanner.

so- our app just happens to scan at 200dpi lineart :)

watch the sane list for more updates to the driver later in the week.
