It appears to be a pretty bog-standard Android phone that should present as an MTP device. Output from dmesg says
ugen0 at uhub1 port 2 "Unihertz Jelly2" rev 2.10/2.23 addr 3 usbdevs says it's a addr 03: 0e8d:2008 Unihertz, Jelly2 I'm not sure how to go about adding those USB IDs, but hopefully this is enough to get it listed in the right place. This is on "7.0 GENERIC.MP#232 amd64" (generic -RELEASE). My hope is to get a simple-mtpfs mount at a minimum. I can provide further information if needed. Thanks, -tkc
