So I have been happily using my Epson Perfection 2480 Photo for years from Microsoft Windows 7, Microsoft Windows 10, and various GNU/Linux distributions, and it's still going strong. Occasionally, for mysterious reasons it freezes, and when it does the only way I can get it to reset, which is indicated by a brief activation of the scanning arm, is to plug it into a Microsoft Windows system. I have found no way to reset it solely from GNU/Linux, which is currently my preferred operating system.
This is a summary of my Arch Linux SANE configuration:
I've been using for a few years now Arch Linux with SANE installed, then iscan-plugin-gt-f500 from the AUR such that I can get reports like this:
$ scanimage -L
device `snapscan:libusb:002:004' is a EPSON EPSON Scanner flatbed scanner
When it's seized, I get reports like this:
$ scanimage -A
Output format is not set, using pnm as a default.
[snapscan] Cannot open firmware file /usr/share/sane/snapscan/your-firmwarefile.bin.
[snapscan] Edit the firmware file entry in snapscan.conf.
scanimage: open of device snapscan:libusb:002:004 failed: Invalid argument
and then no amount of unplugging of the scanner and even rebooting of Arch gets my Epson Perfection 2480 Photo reset such that I can scan again. The only thing that works is to briefly plug it into a Microsoft Windows machine. I had the same snag in previous years when I was using esfw41.bin instead of iscan-plugin-gt-f500. How can I avoid this, and reset it from GNU/Linux?
