Subject description: xsane finds no name webcamera but not HP 1510scanner
 

Hi,
running LxPupSc 16.09.1 on an Acer Aspire E15, I have installed hplip3.16.5 and my printer is working but not the scanner;
both xsane and peasyscan give me the webcam.

# scanimage -L
device `v4l:/dev/video0' is a Noname HD WebCam virtual device

#sane-find-scanner
gives me ...

found USB scanner (vendor=0x0bda [Generic], product=0x0129 [USB2.0-CRW]) at libusb:002:008
found USB scanner (vendor=0x03f0 [HP], product=0xc111 [Deskjet 1510 series]) at libusb:002:010
could not fetch string descriptor: Pipe error

I have reinstalled printer and hplip several times, but am now stuck.
Appreciate any help
Thanks

Martin

Remove the webcam, reboot with the printer connected and on, then rerun scanimage -L

Is there a difference?

Hmm, tricky waters..

You may have to create a custom file and add your device in order for it to be properly utilized.

In the event it's a permissions issue >> https://wiki.archlinux.org/index.php/Sane#Permission_problem

Hi Semme,
thanks for your ideas.
a) i cannot unplug the webcam, its built in. I did try rebooting with the printer on but this didn't solve the issue
b) custom file, I could not find a reference to HP1510 in the list so i don't know which custom file to use.......
c) permissions haven't tried this yet
d) hp-check gives me an error " no python "

what worries me is that there is no scanner at /dev, xsane surely cannot find a device that isn't there ??

Unfortunately my time ( and Linux knowledge) is limited and I think I am going to try to reinstall puppy on a new stick, as I did have this scanner working with a previous build of LxSc.

Many thanks for your help, will report back next week when I've had a chance to look at this all again.
Cheers
Martin

One more option. Try in terminal:

Code:
modprobe -r uvcvideo


to uninstall the webcam. Then try xsane again. To load the webcam driver again:

Code:
modprobe uvcvideo

Watchdog, thank you for the hint BUT...
xsane gave me just one window <<Failed to open device " ' Invalid argument>>
scanimage -L gave me no connected scanners
sane-find-scanner gave me both scanners as before.
this evening I will try your command and reboot, maybe the machine has to find the scanner at boot time ???

Cheers
Martin

Is your pup 32 bit? Try to install this one:

The command:

Code:
modprobe -r uvcvideo


is to be executed after boot.
