Pixel 7a
Grapheneos (on main Profile)
windows 10 with subsystem Linux Ubuntu (Android Studio and adb driver installed)
Tails OS (optional, no adb drivers yet)
in order to run a test on my grapheneos device, i have to make an adb connection.
i enabled adb connection in developer options
i ticked allow usb peripherals
in usb preferences i tryed out data transfer, no data transfer, midi, ptp and this device and connected device
*tick connected device always endet with error
when i type adb devices in any command prompt (in WES ubuntu or in windows cmd) i dont see any device but my computer makes the usb connection sound. sometimes my computer says that the usb device is not ready for use, but for the most, the usb connected sound is all sign of connection at all.
i tryed on a windows 10 pc with WES Linux subsystem Ubuntu (updated) with adb driver installed on windows and on Ubuntu.
also i tryed on tails (adb installed) but the same outcome here.
PS i did not even get a promt pop up on my grapheneos device for the authorisation of adb debugging from my pc.
in the notifications there stands usb debugging connected, but nothing more.
what can i do to make the usb debugging connection i need?
