It might be possible to update the PCI Id database, but I am not sure
if it will help you in this instance. You might give this a try:
if [[ -n $(command -v update-pciids 2>/dev/null) ]]; then
echo "Updating PCI Ids"
update-pciids -q 1>/dev/null
fi

MTP is a file transfer protocol. I see it as an option on Android. I
don't recall it creeping into my Linux desktops.
You might try to look at how the ANCEL program communicates with the
device. For that, I recommend installing Windows into a VM, and then
installing a port monitoring program to sniff the traffic. I would
guess USB-OTG has something to do with it. You want the battery tester
in device or slave mode so it transfers data.
