I've copied the stats included in my original message again here for
convenience.
Windows does not have the same speed problem when running natively
(SMP or UP), but it does when running under SMP & VMWare 3.0, which
uses usbcore.o, usb-uhci.o ro uhci.o to access the USB devices but not
SANE.
Yes, scanning is at same resolutions. It can be easily reproduced by:
1) Booting SMP kernel
a) run XSane in preview mode - takes about 3-4 minutes.
b) rmmod scanner.o, Run VMware, scan with Epson in preview - takes
about 4 minutes.
2) Boot in non-SMP kernel
a) run XSane in preview mode - takes about 8 seconds
b) rmmod scanner.o, Ron VMware, scan with Epson in preview - takes
about 8 seconds
I'll be doing some packet transfer tests shortly, recompiling kernel
with CONFIG_USB_DEBUG=y now.
