Hi Matthias & all,

Yes, you'r right, thanks, Tethering the smart phone kills
the adb direct over usb connection, not surprising in retrospect ;-)

I don't know what file on bsd or android you refer to. (Fortunately
android 6 has find & grep (earlier does not)), but I find nothing
with these:
On android:
cd /etc;find . -type f -exec grep android-gadget-service {} /dev/null \;
On current freebsd :
man urndis
cd /usr/src ; find . -type f -exec grep android-gadget-service {} \;

Too cryptic, not sure what you mean.
attach is not a command on android 6 or freebsd current
uname -a
Linux localhost 3.4.0-12884729 #1 SMP PREEMPT Mon Jan 15 16:53:44 KST 2018 armv7l
shell@klte:/ $
Though attach is a label for bsd /etc/devd/*.conf
& I recall attach a dev to an interface of old, eg slattach etc.
& on freebsd current : apropos attach : man devmatch
& devinfo | grep rndis # only shows urndis0 when I click tether on android

Yes, ths was my problem after tethering I was not seeing any devices,

PS Later I'll tether again. My end aim is find an app for android
that supports NFS & AMD, so the phone can seamlessly become part
of my file system on BSD. but a search on http://play.google.com
& http://www.fdroid.org shows nothing obvious.
I'll probably have to root the phone too before that, & I didnt
root, till after I could backup, & backup wasnt easy with no knowledge
of FS tree, & no commands find & grep on my older android, & locked
read permissions in non root, it was chicken & egg.
Tips welcome, I add them to my http://www.berklix.com/android/
Thanks
Julian
