I just did a test with 7 USB scanners scanning at the same time on the
same computer: no problems, no errors, just slow :-)

Tested devices:
Canon LiDE 35/40/50 (genesys)
Genius Colorpage Vivid 1200 XE (gt68xx)
Plustek OpticPro U16B (gt68xx)
Mustek Bearpaw 1200 CU Plus (gt68xx)
Mustek BearPaw 2400 CU Plus (gt68xx)
Mustek BearPaw 2448 TA Plus (gt68xx)
Mustek BearPaw 1200 CU (gt68xx)

Linux 2.6.13 using libusb 0.1.10a, current sane CVS.

Bye,
