I’m not sure if this is a problem with my Thinkpad T480s laptop running Debian 11 (bullseye) or the Librem 5 USA (byzantium), but when I plug the phone into the laptop’s USB 3.1 Type-C port, dmesg on the laptop shows:

The L5USA is able to charge from my laptop’s USB 3.1 Type-C port, but the L5USA’s dmesg shows:

What do other people see when they plug in their L5 to a USB-C port on a PC?
