Ah, thanks for the explanation. I am pretty sure I had USB Debugging enabled on the Fairphone, but I’ve never connected to it via ADB before.
If I connect my Galaxy A13 to my laptop now, then the prompt ‘Allow access to phone data?’ appears at the bottom of the phone display and the device appears for ADB (before I’ve made a selection on the prompt):
me@laptop:~$ adb devices
List of devices attached
RF8TA08EZRM device
But as I said, when I connect my Fairphone to the laptop there is nothing shown when I run adb devices (but the phone LED comes on and the device appears as a removable drive in the File Browser):
And it appears after running lsusb, as an MTP device (although misidentified as a Google Nexus/Pixel):
me@laptop:~$ lsusb

I’ve just tested something with my Galaxy: I restarted the device and then connected it to my laptop before entering my PIN. It appeared as a removable drive, and when I clicked on it I got the same timeout and MTP error, which tells me that my Fairphone is still in the immediate post-boot state (i.e., I haven’t entered my PIN, so the disk has not been decrypted yet). However, I’m not sure why it isn’t showing up for adb devices, as the Galaxy does even before I first enter my PIN.
After entering my PIN on my Galaxy, I am able to mount the phone on my laptop but it shows it as empty until I press ‘Allow’ on the access popup.
So I think that firstly, I need to get to at least that state with my Fairphone (i.e., able to mount it, but with the drive showing as empty) to prove that I can interact with the device enough to enter my PIN to complete the boot process. I’m not sure what to make of the fact that the Galaxy shows up for adb devices and the Fairphone doesn’t though, since I’m not familiar with ADB prior to this.
To that end:
If anyone is currently using /e/OS 1.5, would you be able to post a screenshot of the default power menu (i.e., the menu of icons that appears along the top of the screen when you hold the power button down for a second)? If I hold down the power button on my Fairphone I get the small vibration that tells me that that menu is being displayed, and IIRC I need to click the middle button (of the 3) to show the Shut Down and Restart buttons, and then I can click one of those, but it doesn’t seem to be working. If I can make the phone shut down/restart, then I know that I definitely do have mouse interaction, so I want to rule out the possibility that I just forgot what the menu layout is like first.
