I'm keen to install LineageOS on my old Pixel 2 XL (taimen). I'm following the instructions at https://wiki.lineageos.org/devices/taimen/install/ and I'm stuck on step frickin' 1.
I'm using MacOS 26.5, although I've also tried on Windows 10. I successfully installed adb and fastboot (long ago; I've updated recently). I've wiped the Pixel. Developer options are enabled, USB debugging is enabled, "Disable adb authorization timeout" is enabled, Default USB configuration is "File transfer / Android Auto" (although I've tried USB tethering, MIDI, and PTP).
When I reach step 6 under "Setting up adb", I get an empty list. system_profiler SPUSBHostDataType shows a bunch of USB devices, but no pixel | taimen | google.
I tested the cable with a different computer and an iPad (hurray for USB-C), and it synched with the iPad: I'm pretty sure the cable is good.
I've tried a USB-A port directly on the back of the Mac Mini, as well as two different USB-A ports on an old hub. Both of the ports connect to my old trackball, so I'm pretty sure the ports are okay. Both are black.
I've tried a USB-C to USB-C cable, again testing with an iPad to make sure it worked for data.
I tried a MacBook and a Windows 10 laptop.
I ran the adb server with ADB_TRACE=usb, and it occasionally reports usb_osx.cpp:168 Unable to create an interface plug-in (e00002be).
About every 15 seconds, the system log reports:
Jul 17 00:01:45 mini MobileDeviceUpdater[1031]: Entered:_AMMuxedDeviceDisconnected, mux-device:9830
Jul 17 00:01:45 mini AMPDeviceDiscoveryAgent[1407]: Entered:_AMMuxedDeviceDisconnected, mux-device:9830
Jul 17 00:01:45 mini MobileDeviceUpdater[1031]: Entered:__thr_AMMuxedDeviceDisconnected, mux-device:9830
Jul 17 00:01:45 mini AMPDeviceDiscoveryAgent[1407]: Entered:__thr_AMMuxedDeviceDisconnected, mux-device:9830
And increments the mux-device number.
NOTHING will recognize this phone. I'm at the end of my rope. What am I doing wrong?
