Hi,

Success!   Thanks for the help ... More comments below as I had to
revise your instructions a bit, probably due to gentoo.

I had added it,  following the example comments in the file when it
wasn't working without it.  I removed, it and at that point it finds
nothing at all,  so on to the next step...,

The "normal locations" assumption is the key.  After locating the files,
I had to use:

sudo iscan-registry --add interpreter usb 0x04b8 0x013a 
/opt/iscan/lib/libesintA1 /usr/share/iscan/esfwA1.bin

On gentoo, the firmware is in /usr/share,  but the .so files are in /opt

The files are indeed installed in /var/lib/lib/iscan for whatever
reason.   Probably an error in the gentoo ebuild,   But it's consistent,
so iscan is looking in the correct place.  I didn't have to move anything.

Yes indeed.  With the registry correct,  it's loading now without any
significant delay.    Thanks again for the help

By the way, I just checked the Gentoo ebuild for the gt-x820 plugin.  It
*does* correctly register the interpreter at the required locations.   I
have no idea now why my system was broken,  but to be certain, I just
uninstalled and then re-installed iscan-plugin-gt-x820,   and the
firmware was correctly removed, and then added to the registry.   And
everything is still working.
