uscanner0 permissions
I have been very happy with a recently installed am64 current desktop but am hav
ing difficulties scanner as a user. I have xsane installed and see my HP 5200C scanner attach to uscanner0 in the dmesg. I am a member of the wheel group. When I start xsane it says no scanner found What I think is the pertinent part of my dmesg Quote:

I am going to try adding myself to the saned group which I just found but say nothing that this is needed for user access. Output of sane-find-scanner Quote:

Managed to work through it.
Even though man uscanner lists the HP 5200C as a supported device the vendor ID is not found. If is disable uscanner the device is attached to ugen0 which works. |

Yes, SANE includes its own userland drivers.. it access the devices using libusb which only works for devices attached as ugen(4).
It's probably better to do it this way, I don't believe the uscanner(4) interface is well maintained. Just speaking out of my.. uhh.. face.. but it may even get removed one of these days, maybe not. |

HP C5200 can scan directly to flash memory card which can be mounted as umass storage device on OpenBSD. Look for my posts on misc under the name "scanning without SANE".
uscanner as pointed earlier should be probably removed from the code. In any case you should disable uscanner driver in kernel as ugen driver has to be attached to your all-in-one in order to scan. Google for my posts about HPLIP on OpenBSD. |
