I'm trying to switch my OnePlus One from CyanogenMod to LineageOS, and to do so I need to use adb adn fastboot. I use Fedora 28 as OS on my PC, with the latest Gnome as DE.
The usual "data" connection works fine, meaning that I can access my phone's internal storage and copy files from/to that memory. Trying to use adb, I I changed the USB mode to "charge" and enabled adb from the Developers Options menu under Settings.
As soon as I connect my phone to the PC, it looks like it is stuck in a loop of connecting and disconnecting the device. I don't see any prompt on my phone regarding the adb connection, and dmesg shows the following output:
new high-speed USB device number 31 using xhci_hcd
usb 3-2: New USB device found, idVendor=05c6, idProduct=6765, bcdDevice= 2.32
usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 3-2: Product: A0001
usb 3-2: Manufacturer: OnePlus
usb 3-2: SerialNumber: 23deaeca
usb 3-2: reset high-speed USB device number 31 using xhci_hcd
usb 3-2: device firmware changed
usb 3-2: USB disconnect, device number 31
where the device number starts with 1 and goes up, and up, and up, until I physically disconnect the phone.
adb start-server (executed as root) shows no error whatsoever, but adb devices shows nothing (both as root and as regular user (not sudo)).
What's happening here?
