Wow. I'm lost on this one. I have an LG phone (a dumb phone, actually a Verizon Exalt VN220) that, for whatever reason, isn't getting recognized as a usb-storage device. I've verified that other USB drives are working fine and create a /dev/sdc or whatever. I also was able to mount this on a Windows 10 machine with no problem.

When I connect it I get only this in the message log and is dmesg:

Code:
Mar 31 14:18:49 dell2 kernel: usb 1-3: new high-speed USB device number 2 using ehci-pci
Also, the following entry gets added to the output of lsusb:
Code:
Bus 001 Device 002: ID 1004:62ce LG Electronics, Inc.
...but that's it. It never gets detected as USB mass storage. Any ideas if there's something I could be missing in the kernel? Sort of perplexing because again, other devices work fine.

Thanks!
Tom

Oh man. Looking at the device properties in Windows it says this is a Generic Hierarchical. Frankly that's s new one on me. If anyone knows anything about I'd appreciate any info.

EDIT: From what I'm reading I'm starting to get the impression that this may mean it's using MTP (media transfer protocol) or some such BS. yuk.

Thanks!

tld,

Phone vendors haze always hated using USB-Storage. In the early days in all there was.
As its not possible to safely mount most filesystems in two places at the same time, users hand to unmount the storage from the phone, then mount it on the PC.

The first 'improvement' on this was Picture Transport Protocol (PtP). for a while phones were produced that supported both USB-Storage and PtP. It was a user selectable option.
PtP had the great advantage that users didn't have to fiddle about with mounting.

Both USB-Storage and PtP have been replaced with Media Transport Protocol. It looks and behaves like filesystem it even has a mount command.

There are several implementations in Gentoo. The Wiki has an overview.

Thanks! I actually just figured that out before reading this. Pretty grim so far though. I installed sys-fs/mtpfs. I was actually only able to mount it as root (despite setting user_allow_other in /etc/fuse.conf). However that aside, once it was mounted I was only able to see directories and NOT any files at all.

Not looking too promising so far.

EDIT: For what it's worth, here's the messages I got when I mounted it:
Code:
mtpfs ~/mount
Listing raw device(s)
Device 0 (VID=1004 and PID=62ce) is a LG Electronics Inc. LG G5 Phone.
   Found 1 device(s):

Thanks!...not sure I'm interested in that for several reasons though. I'm really not looking for a player as much as just a way to transfer files. Also gmtp requires gtk+-3 which I'm certainly not installing just for that.

For sake of truth, gMTP is for file transfer.

Ahhh...my bad. Thanks for the clarification. From other things I've read on the forum I'm giving gphoto2 a shot.

OK...looks like gphoto2 does in fact work. I have some questions about that but I'll put them in a separate topic, probably in the multimedia forum and mark this as solved.
