Err... Correction: the line 'usb 0x04b8 0x0110' says that the device with vendor ID 0x04b8 (that would be Seiko/Epson) and device ID 0x0110 should be opened using this epkowa library - this is the driver that you downloaded from the Epson website. The device ID is actually 0x08b8, not 0x0110. You can see it in the list displayed by the 'lsusb' utility.

So: the file /etc/sane.d/epkowa.conf should contain this line:

usb 0x04b8 0x08b8

Note that in my case it works without it, but I don't know what is happening on your computer.

Cheers,
Mihai

Mihai,
I rebooted my computer and ran the groups check again. This time, the word "scanner" appeared in the result.

However, when I tried running
scanimage -L
the result was
device `epson2:libusb:001:009' is a Epson GT-8300 flatbed scanner

Still no sign of the WF-3620.

Mihai,
There is no such file in my /etc/sane.d folder.

Hmm... Did you download and install a file called iscan_2.30.1-1~usb0.1.ltdl7_amd64.deb from the Epson website ?

No. The one I tried to install when I set up the printer was
epson-inkjet-printer-escpr_1.4.4-1lsb3.2_amd64.deb

I got a message saying that it was already installed, so I went ahead and finished hooking up the printer.

I know - those are the configuration files for the drivers for older models and are part of the standard Linux Mint distribution (as far as I know).

The driver you need is a file called /usr/lib/sane/libsane-epkowa.so.1.0.15, which comes from the iscan_2.30.1-1~usb0.1.ltdl7_amd64.deb package from the Epson website. The configuration file for that driver is /etc/sane.d/epkowa.conf and comes from the same package. I wonder how did it ever work for you without it...

epson-inkjet-printer-escpr_1.4.4-1lsb3.2_amd64.deb is only the printer driver. For the scanner you need to install two more:

iscan-data_1.34.0-1_all.deb
iscan_2.30.1-1~usb0.1.ltdl7_amd64.deb

Optionally, you can also install iscan-network-nt_1.1.1-1_amd64.deb (for scanning/printing over the network).

Oh, yes - Epson. "Professionals" at work. Why oh why did I not stick to HP ? :-)

If you trust that I'm not sending you malware, I placed copied of those file on my server: http://www.platios.eu/Epson
I will keep them there for a couple of days.

It worked! At least for today. The scanner still doesn't come up in the device selection menu for either Simple Scan or gscan2pdf, but if I unplug the older scanner then the new one becomes the default. I just tried scanning something on the flatbed using Simple Scan and was successful. Will try the ADF sometime soon, and if that works too, I'll mark this thread as solved. Thanks so much for your help and patience.

Glad to hear :-) With gscan2pdf you can specify the device you want to use on the command line, like this:

gscan2pdf --device=epkowa

Simple Scan probably supports something similar. Well, have fun with it.

Yes, that was the weird thing -- the new scanner didn't show up even after I installed the scanner drivers. My computer does send to it as default if I unplug the older unit, though. Mystery.
