I just finished setting up my HP LaserJet Professional M1212nf MFP on Ubuntu wirelessly (IPV4 address). In terms of scanning, it works properly with Xsane and simple-scan. 

But VueScan 9.5.53 (x64) doesn't detect it. I installed it manually from the VueScan website's tarball. Whenever I select the 'Scan' option, I get this message:

> 
> VueScan didn't find a scanner connected to your computer.
> 
> 
> 1) Make sure the scanner is plugged in and turned on before you run VueScan.
> 
> 
> 2) If you have a USB scanner, try a different USB cable and/or a different USB port.
> 
> 
> 3) If you have a WiFi scanner, make sure your firewall isn't blocking responses from the scanner.
> 
> 
> 4) If the scanner has a locking switch, make sure it's in the unlocked position.
> 
> 
> 5) Try turning your scanner off and back on.
> 
> 
> 6) If you have a USB scanner, try running VueScan as root to see if it's a libusb device protection problem.
> 
> 
> Then exit VueScan and run it again.
> 
> 
> The supported scanners list has more useful information about your scanner. Would you like to see this?
>

This message appears even when I have the printer's USB plugged into my computer, and even when I run sudo ~/Desktop/VueScan and then try wirelessly scanning or scanning with the printer's USB plugged in.

Did I install VueScan the wrong way? I used the 'tar xvf' method to extract it to my Home folder. There's a hidden folder (.vuescan) in there with an .ini and .log file.

The .log file (vuescan.log):
