What has RNDIS (ethernet=internet over USB) has to do with file transfers.
I don't want a work around, I want MTP working both ways. IMO the problem is
how the phone is recognized but I'm not sure if it is coming out of
konqueror or from the new kernel I installed few days ago ... or may be the
whole series of kernel I used in the past few months.

I use Sailfish OS - after using debian based Nokia N9, I could not become a
friend of Android and adopted the evolution of the meego called mer - but
it is the same in the background (I mean they use the android kernel by
Sony AOSP and put the Sailfish OS on top. There are also many community
ports for various makes and models)

What is bothering me  is this:

[Wed Oct 28 09:26:39 2020] sd 6:0:0:0: [sdb] Attached SCSI removable disk
[Wed Oct 28 09:26:40 2020] usb 2-1.3: USB disconnect, device number 21
[Wed Oct 28 09:26:42 2020] usb 2-1.3: new high-speed USB device number 22
using ehci-pci

It recognizes as removable this but then it says disconnect 21 and new
high-spped blah blah 22.

May be I ask in Debian User
