Re: [Ubuntu-phone] UMS instead of MTP

[Marcos Alonso]

Hi Ferdinand.

I' m using Linux Mint and OpenSuse.

I have the issue with LM. RAndomly does not connect or, if connected,
disconnects suddently.

Is not a HW issue as OpenSuse on the same laptop does not fail.

And both systems are updated. May be some bug...

Thanks.
Marcos

Hi there,

never had any problems with Ubuntu Phone using MTP. Do you use Ubuntu on 
Desktop too? Which version is it? Maybe there is an update for that.


As far as i know there is only MTP supported. Just like on any modern 
Android phone too. Well.. you could also use adb. But it's not very user 
friendly. :D

I know MTP has some benefits in terms of safety but I jst connect to 
my PC and I' m tired of how bad MTP performs in Linux.


Thanks!

Re: [Ubuntu-phone] UMS instead of MTP

[Ferdinand Holzner]

Ok, i know there were some problems with MTP some time ago. I'm not sure 
which version it was... However, in Ubuntu 15.10 it seems to be fixed. 
So i guess having the equivalent to that from Linux Mint could deliver 
this fix too. What version do you have? You can find out with this 
console command:


lsb_release -a

17.3 should be the most recent version. I didn't follow the update cycle 
of Linux Mint, so i don't know how recent it is compared to Ubuntu.


Please also keep in mind, that the display of the phone must be on and 
unlocked. Otherwise it won't connect. I'm not quite sure yet, but maybe 
it also disconnects after some time if the screen goes off. Apparently 
that's a security feature.

UMS means you need to have your disk formatted with a filesystem the
connected PC knows (so if you want to be windows compatible you need to
use vfat or NTFS, if you want to be windows and mac compatible only vfat
is left). while it might work for devices with SD card to export the
card, it wouldnt work for directories in your home dir (vfat does for
example not support symlinks, so you couldnt just format the home
partition with it, many things would stop working then).

android used work around this by creating virtual sdcards that are vfat
formatted and (loop)mounted ... now that they switched to MTP nearly
everywhere they have to carry that hackish legacy forever (apps use the
sdcard path hardcoded for their data etc. to keep them running you need
to keep the mess around) at a high maintenance cost.

MTP should not be any slower than UMS though, they are both rather
hardware bound wrt. speed (i.e. as fast as the USB connection). if you
really expect issues with MTP here you can enable developer mode to use
adb push to compare the speed and actually file a bug about MTP if you
find they differ much.

assuming you have wifi where your PC is connected i'd suggest to take a
look at stuart langridges WifiTransfer from the app store (you need to
move the data around afterwards with the file manager though if you want
it in a common dir like "Music" or "Videos" but depending on your
network it is likely a lot faster than USB).

Hi Oliver.

Thanks for your feedback too.

I see moving to UMS is not that easy.

I will work with the issue source (my PC).

It was not a matter of speed, etc. Just connect or not connect issue.

And yes, I also use WifiTransfer but is a little bit invonvenient with
large files as if the screen switches off, the file transfer stops!

Thanks anyway!
Regards
