I came across a Epson Perfection V39 and thought I'd try getting it to work on Linux Debian.
I have installed xsane, gscan2pdf and sane-utils.
When plugging into USB, /var/log/messages has:
Jun 25 23:16:04 usb 1-1: new full-speed USB device number 22 using xhci_hcd Jun 25 23:16:05 usb 1-1: new high-speed USB device number 23 using xhci_hcd Jun 25 23:16:05 usb 1-1: New USB device found, idVendor=04b8, idProduct=013d, bcdDevice= 1.00 Jun 25 23:16:05 usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Jun 25 23:16:05 usb 1-1: Product: Epson Perfection V39 Jun 25 23:16:05 usb 1-1: Manufacturer: EPSON Jun 25 23:16:05 usb 1-1: SerialNumber: VCFY057184
I tried creating the following file:
# cat /etc/udev/hwdb.d/epson-v39.hwdb # Epson Perfection V39 usb:v04B8p013D* libsane_matched=yes
and running 'systemd-hwdb update', but no luck
From a different perspective, Epson Drivers can be used to find the drivers. Put 'V39' only as the search criteria. One of the versions shown is 1.0.1, but v1.0.4 is actually available at v1.0.4. I wish there was a directory to browse as I found that one by trial and error on the url line.
However, skipping all that, this is the one that worked with xsane on Debian Buster: Image Scan! for Linux 1.0.1.
The scanner is seen:
iscan-gt-s650-bundle-1.0.1.x64.deb# scanimage -L device `epkowa:interpreter:001:025' is a Epson (unknown model) flatbed scanner
As a side note, the 1.0.4 version provided a mechanism of seeing network based scanners such as an HP multifunction.
For future reference, find a scanner which is compatible: SANE - Supported Devices
