With ehci-hcd, either as module or as in-kernel, when trying to scan from Vuescan 8.0, I get in /var/log/messages:
May 18 23:48:09 pit kernel: usb.c: registered new driver usbscanner

The scanner is blocked, blinking, and so is Vuescan. When I shut down the scanner:
May 18 23:49:33 pit kernel: scanner.c: write_scanner(0): funky result: -71. Consult Documentataion/usb/scanner.txt.
I have tried with shorter timeout (60), then I get the same, plus
May 19 00:09:52 pit kernel: usb_control/bulk_msg: timeout.
The error does not appear when I am using the UHCI driver compiled as part of core - not as module where I still have problems.
From post on comp.periphs.scanners, it seem that Vuescan is compatible - in some cases - with ehci. So where could the problem come from? From the ehci / usbscanner / Coolscan V combination? Any common or reasonable reason?
Thanks for your help. Yannick
