Thunar has a lot fewer moving parts and uses libmtp directly. Krusader 
likely relies on a lot of extra KDE IPC goop implementing a virtual 
filesystem layer sitting between the mtp library and the file manager, 
that might not be working well together for some reason, possibly 
version skew. (Gnome and Mate also do that, and on my system neither mtp 
nor smb work reliably through gnome-vfs.)


Ya, what he said!  Thank you for the help!

Krusader will not recognize my wife's tablet.  But Thunar
does as mtp://[usb:002,010].

I can not find it on the command line.   :'(

I would like to write a backup program to backup up
my wife's files.

Question: how do I access mtp://[usb:002,010] from
both the command line and from Perl 6?

Many thanks,

Figured it out.  Now I get top start coding!  :-)

With a lot of help from Vladimir over on the Scientific Linux
mailing list, here is my write up:





SL 7.4: how to operate MTP devices from the command line:

First download and install libmtp and libmtp-examples from:
http://people.redhat.com/bnocera/libmtp-rhel-7.5/


$ yum --enablerepo=* whatprovides simple-mtpfs
...| 2.6 kB 00:00
simple-mtpfs-0.2-3.el7.nux.x86_64 : Fuse-based MTP driver
Repo: nux-dextop

# yum --enablerepo=* install simple-mtpfs libmtp-examples

One time:
   # mkdir /mnt/mtp
   # chmod 2777 /mnt/mtp

Mount:
   # mtp-detect
   # sudo simple-mtpfs -o allow_other,direct_io /mnt/mtp

Unmount:
   # fusermount -u /mnt/mtp

Thunar has a lot fewer moving parts and uses libmtp directly. Krusader
likely relies on a lot of extra KDE IPC goop implementing a virtual
filesystem layer sitting between the mtp library and the file manager, that
might not be working well together for some reason, possibly version skew.

No MTP support module for Perl 6 as yet. There's a suite of command line 
utilities, but they're *fugly*. (The package is called mtp-tools on 
debian-derived systems; I don't know what rhel/fedora call it.)


Use 'mtp-files' to get a listing of files and their ids, and then 
'mtp-getfile' to copy a file by its id (not name, at least not in the 
version of mtp-tools I have). So to grab a backup settings file from my 
old phone (whose mtp implementation doesn't work with current linux file 
managers that speak mtp) I ended up doing:


     mtp-files >5x.txt
     grep -B1 -F k9s 5x.txt
         (this reported file id 4325 for the settings file)
     mtp-getfile 4325 settings.k9s
         (this retrieves file 4325 and saves it locally as settings.k9s)

You may need to use mtp-connect to discover the tablet and find out what 
settings are needed to make it the default device for mtp operations.


Thank you!
