Won't mount to Ubuntu

[BlackHawkA4]

When I first plug in the phone and it is set to HTC Sync the drives will show up on ubuntu. You can see all the folders and files but can't access anything. When I switch to disk drive they disappear and never connect to the computer. I have an SD card in so I'm not trying to access the phone storage.

Anyone know a fix to this?

I would change the subject to "Linux" instead of Ubuntu (Ubuntu is *a* Linux distro, but Linux is not Ubuntu).... but that aside...

NEITHER of my computers (Mageia 2 and Fedora 17) will see it with USB Mass Storage mode anymore, only that stupid MTP stuff (which is brain-dead/broken and acts like you describe). I suppose it is possible they changed the USB ID's on the device in some way that Linux doesn't understand yet. Very irritating. Thank GOD for Airdroid. This is all I get now:

MTP mode:

You will notice in the second listing, it was never assigned a device name or node. I have reported this to HTC just now (since you are confirmation that it is not just my phone or systems). Hopefully you will too, and anyone else reading this who is irritated by this regression in functionality.

Just for sport, I also tried to use "gnomad2" to talk to the Evo LTE in MTP mode (since I have used that before successfully on my Motorola Xoom) and it failed miserably also:

Device 0 (VID=0bb4 and PID=0f91) is UNKNOWN.
Please report this VID/PID and the device model to the libmtp development team

I suspect "HTC Sync Manager" is more proprietary than just plain MTP in some way. Thanks a lot, HTC.

Yea. I thought it might just be an ubuntu thing since ububtu does some weird things. I guess its a linux wide thing.

The only work around I found was to just use twrp recovery to mount.

Yep. Really, you should change the subject of the topic to reflect that...

I am not familiar with "twrp", sounds interesting though. But seriously, have you ever tried AirDroid? It is probably the most awesome Android app ever! It will be a hell of a lot more convenient than rebooting the phone, and can do so much more.

I am not having a happy exchange with HTC support on this issue. Sometimes when I report something, I get someone with a clue. Other times, apparently like this time, I get someone who doesn't read what I send them or doesn't understand technology sufficiently to be in support. She is starting to pull the "we don't support Linux" crap but without directly saying that. The last suggestion was that I perhaps I have a driver conflict (???? under Linux???) and I should try it under an MS-Windows or MacOS system. Geesh. Waiting to see where this goes before I get all bent and into combat mode.

I hardly ever use a USB cable with my phone. But leaving Linux users (who have systems that comply 100% with USB standards for USB Mass Storage Mode) with no way to connect via USB cable to a phone that runs Linux is pretty insulting.

We don't support linux. We just run it on ours phones.

Just got off the phone with a REAL HTC Tech and have a reasonable answer for this now. There is no USB Mass Storage mode at all anymore. "Disk Drive" is now MTP. Although I can use MTP mode on other Android devices under Linux, I still can't with the HTC Evo. Not sure why, though. I did tell them this is a problem for me, and supposedly it will be escalated.

When I attempt to use HTC "Sync" mode, that apparently uses PTP mode, and my systems detect that, but no pictures are present (even though kernel messages say it is MTP mode). When I select "Disk Drive", which is supposedly MTP, the kernel messages say it is *NOT* MTP, and none of my tools for working with MTP detect the phone at all.

At least I have a better understanding of some of what is going on now.
