lost usb tethering android 7.0 after an update from android 6.0.1 to android 7.0  i ve lost usb tethering function on samsung tablet wifi SM-T580 !   

need update to recover this function which is very important for me because i use this tablet only to connect to Remote controller  of drone  via usb tethering  . Without this function this tablet no longer serves me and the drone too . 

thank
Check what type of connection it is using, take down the notification drawer and see if there is a "Recharge" notification or something like that.

If so, tap on it and choose the MTP option, then go in the tethering options, and activate it.

Done :)
