usb/ Bluetooth connection switches off and on
When I connect an iPhone to one of the USB ports of my MacBook Air 2017, it keeps on reconnecting a few times per second. When I connect through BT, it connects, the bluetooth app says its not connected, while I can access it. I reinstalled Catalina (clean install), but to no avail. Any ideas?
MacBook Air 13″, macOS 10.15
