Just re-installed 18.04 because of the problems I was having with 20.04. At any rate I have the Epson ET-3850 EcoTanker.
I was provided the following terminal command line: lsusb -v | grep -A 3 bInterfaceClass.*7
I ran it and got the following results.
rich@rich-500-164:~$ lsusb -v | grep -A 3 bInterfaceClass.*7
