Thank you! That got me a step forward.
Looping two or even three times didn't help, the set_config
just continued to time out and fail. Then I followed your
second advice and inserted "err = 0;" so the error was
ignored. Now the device attaches! »usbconfig list« says:
ugen0.1: <OHCI root HUB nVidia> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON
ugen1.1: <EHCI root HUB nVidia> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON
ugen0.2: <Scanjet 4300C Hewlett Packard> at usbus0, cfg=255 md=HOST spd=FULL (12Mbps) pwr=ON
Does that mean this device needs a quirk entry or something
like that? I mean, setting err = 0 is a hack, it's not the
proper solution.
Unfortunately I wasn't able to check whether it works with
SANE because I had to catch the train ... I'll continue
with that next week. I hope I can finally make this
scanner work ... The uscanner(4) manpage claims the 4300C
is supported (for years already), but that wasn't true
until now.
Best regards
