cannot mount smartphone anymore

[Emanuel Berg]

I use to use this little zsh

#! /bin/zsh
mount-smartphone () {
jmtpfs $(mktemp -d phone.XXXXXX)
}
alias smph=mount-smartphone

to mount the Samsung Galaxy Note 2 LTE GT-N7105 16GB (t0lte,
Android 4.4.2) smartphone filesystem in my $HOME.

But suddenly it doesn't work, it says:

Device 0 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).
libusb_get_active_config_descriptor(1) failed: No data available
no active configuration, trying to set configuration
libusb_get_active_config_descriptor(2) failed: No data available
LIBMTP PANIC: Unable to initialize device
terminate called after throwing an instance of 'MtpErrorCantOpenDevice'
what(): Can't open device

Idea?

TIA

On the phone did you allow the PC to access the phone?

[Emanuel Berg]

I don't remember this was anything one had to do but no, how
do you do that?

I don't use iphone/android, but last time I did (2-3 months ago), when I
plugged the cable it prompted on the phone and asked if I allow the access
for this device.
If it is not prompted look at the logs (dmesg -T) after plugging the cable
and best paste here.

It says, "Connected as a media device".

"Device is not authorized for usage", that's probably the
problem, right?

google says in context of Ubuntu - USBGuard
the package is also in debian - could be you have it installed?

[Emanuel Berg]

I did, and when I removed it, it works again!

Thanks a lot!

Straight expert advice!

Removing usbguard is maybe a drastic decision, isn't?
Or maybe you don't want this package anymore for other reasons?

Otherwise, you could just add a rule authorizing your device to connect:

sudo usbguard append-rule 'allow id XXXX:XXXX serial "XXXX" name "XXXX" hash "XXXX" parent-hash "XXXX" with-interface XX:XX:XX'

sudo usbguard list-devices
will tell you the correct parameters (of course usbguard must be running and your device connected/blocked).

You can generate a ruleset based on your currently attached USB devices
by executing usbguard generate-policy > /etc/usbguard/rules.conf as
root.

I'm for taking the route of least resistance (to my hebetude).

No, why do I need it for?

Anyway it is removed now...

He probably assumed you installed it intentionally, and so for a reason,
as it appears to be an optional package.

Exactly! You should have had a good reason Emanuel to install it at the first place, no?

This package can be useful to limit access to your computer usb ports (in case you leave the machine unattended).

That doesn't sound like me. I have autologin enabled and
I never lock the front door...

But aptitude might know:

aptitude why usbguard


Kind regards,

OK:

i gnome-online-accounts Recommends gnome-control-center (>= 3.6.1)
i A gnome-control-center Depends gnome-settings-daemon (>= 3.37)
i A gnome-settings-daemon Suggests usbguard

Not really a GNOME user so again don't know what that means...

[Reco]

Hi.

It means this, based on the package changelog:

gnome-settings-daemon (3.35.91-1) experimental; urgency=medium

[ Sebastien Bacher ]
* New upstream release:
- Add capability to disable USB while the lockscreen is on
(based on USBGuard)
* debian/control.in:
- Suggests usbguard for the new lockscreen protection, the feature
didn't get much testing yet and usbguard could create problems so
don't bring it in by default yet


I.e. what it should do is to deny any usb devices from configuring while
you have a lockscreen on. The changelog message also shows that
currently one have to install Suggests type of dependency to get this
feature.

This suggests (no pun intended) it was installed manually
(`apt list usbguard` would confirm this), as Suggests are not installed
by default.
