Hi,

I have bought a HP ScanJet 4300C, specifically because
this very scanner is listed in FreeBSD's uscanner(4)
manpage and in SANE's list of supported USB scanners.

However, this is all I get:

uscanner0: <vendor 0x03f0 product 0x0305, class 0/0, rev 1.00/0.00, addr 2> on 
uhub0
uscanner0: setting config no failed
device_attach: uscanner0 attach returned 6
uhub0: port 4, set config at addr 2 failed
uhub0: device problem (TIMEOUT), disabling port 4

That's on 7-current, but it fails the same way on 6-stable.
I also tried on two different machines with different USB
chipsets, and different ports ...  No change.



Most USB devices only have one configuration. You could
try commenting out the call to usbd_set_config_no() and
the related error checking code in the attach routine of
uscanner.

If that doesn't work or you want to investigate further,
adding:

options  USB_DEBUG

to your kernel configuration file will give you some
more useful debugging messages. You can control the
verbosity level with the hw.usb.debug sysctl.
