No USB, no adb, no fastboot, only charging

Dear all,

I got a OP3T which won't connect to my Laptop (Linux, ubuntu 18.04). Since I have a second OP3T which connects with no problems and I allready replaced the USB-Port in the first OP3T I think my problem lies inside the phone:
It cannot be connected further than charging. If I plug it in, shortly the P symbol pops up in the notification panel or if I opened the notification, the selection which mode of connection should be used shows for one second and closes afterwards. Same with the message about USB-Debugging.
What Ideas do you have to fix it?!

PS: I got a corrupted WLAN-MAC Adress, could it be connected?!

Thanks all!!

PS: I posted the same in the Oneplus Forum, but until now, here at xda a got much further information so I try on both chanels...

Long story short, the mainboard of my OP3T died. I got a cracked OP3T on ebay so I could salvage its motherboard and put into my op3t which is in A+ condition. 3 months old battery, 3 months old screen (all replaced by oneplus under warranty). Unfortunately I had the same issue with that OP3T that i got on ebay. ALl working except the USB - PC connection and the dash charging. Will only charge in "normal " (1.6Amp). AFAIK that's a motherboard issue and it's related to some specific IC that gets damaged. So, if you don't have USB-PC connection neither Dash charging available, you better look for a new phone or a new motherboard since it's pretty much irreparable.
