[sane-devel] HP3400c device busy

[Luigi Belli]

Hello to everyone, this is my first post here.
Lurking this mailing list I found a thread back in November about a problem=
=20
with hp3400c and libusb, and I have exactly the same problem :)
However, I can add some informations to better specify that problem.
I have an Asus A7M266 motherboard with the infamous via686b southbridge and=
=20
I'm using the uhci-hcd usb kernel driver.
The 2.4 scanner kernel module worked perfectly, but both libusb and 2.6=20
scanner module (definitively removed from 2.6.3) says that the device is=20
busy.
If unplug and replug the device and immediately access the scanner with any=
=20
frontend it works correctly; same behaviour if I just restart hotplug.=20
Sometimes the device remains accessible for some minutes, sometimes for few=
=20
seconds, sometimes for more than one access, sometimes only for the first=20
access.
These are the outputs of lspci and lsusb:
