Since May update i've lost usb options are greyed, and the phone doesn't connect to any PC, I've tried different cables and PCs. It only charges. I've replaced the usb port and still the same.

Hi,
Does the USB to 3.5 jack audio adapter work?

Yes, audio is OK using the original adapter, but USB OTG isn't.

Have you tried factory reset?

Yes, I did a factory reset after the issue, and it didn't fix anything. So I replaced the USB port (tried with 3 just in case) and is the same issue (fast charging OK, audio OK, but no USB PC or OTG). It must be a software problem because it started immediately after the may update.

Can you enter fastboot mode?

If yes, is the phone detected when you connect it to PC (look Device Manager)?

whether its on normal mode or in fastboot mode, device manager says: device descriptor error, the same error on multiple PCs and on Win 7 and Win10.

Can you show a screenshot of the device manager?
