What happens:
Plugging in the Oneplus one to an Ubuntu computer does not mount or allow MTP.

Seems related to my bug here: ubports#11

Yes, and I should add that my OPO is only visible to a PC with developer mode off, but it still doesn't mount. Turning developer mode on, it is not even visible through lsusb.

[tomoqv]

On 15.04/devel r10 I can finally mount my OPO, but only if I have developer mode set to disabled. When enabling developer mode, the device can't mount again. Seems like the dev mode settings button is inverted.
Regardless of developer mode setting, the device does not expose an adb interface.

Fix released: ubports/device-files@2d65b59 and ubports/build-scripts@9c0f535

This bug appears to have resurfaced lately. I noticed it today on devel r146. Reboot didn't fix it. Last time I connected my OPO to this PC it worked, but it may have been a couple of weeks ago.

What is happening with this? Unfortunate regression of a function that is rather essential. I would very much like to have it back.

[tomoqv]

Just to further some information on this issue.
Following shows in terminal when OPO (developer mode on) connected to my PC:

...:~$ lsusb
Bus 001 Device 002: ID 8087:8001 Intel Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 002 Device 002: ID 045e:00d2 Microsoft Corp.

Dito with developer mode off:

...:~$ lsusb

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 002 Device 002: ID 045e:00d2 Microsoft Corp. 
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Below still with developer mode off:

...:~$ adb devices
List of devices attached
 
...:~$ adb shell
error: device not found

And with developer mode on:

...:~$ adb devices
List of devices attached 
d9a48603	offline

[tomoqv]

I have checked all the steps from this bug report: ubports#11

[tomoqv]

Yeah, and once in a while I get:

...:~$ adb devices
List of devices attached 
d9a48603	device

Then I can do adb pull /home/phablet/whatever_file, but MTP still doesn't work.

[tomoqv]

With devel r170 (today) there is some progress. Still no MTP, but I can now adb shell into the device again.

[tomoqv]

I can see that this is still marked as "needs confirmation". Does that mean it works on other OPOs? The problem persists for me in devel r203.

[Voltcab]

Hello, yes, I have the same problem. My phone is recognized but it is impossible to open it on my PC. I can't transfer my files. I will follow with you the evolution. I hope there will be a quick solution...

[stekalb]

Also an issue on my bacon. (r204)

[BlueKenny]

Same issue on my phone

[andybleaden]

I can confirm this is still a bug. Not how I can help but happy to try. This has been fixed previously I know but keeps cropping up. Not sure why
