Has anyone successfully connected two Framework 16 laptops to each other via the USB4 / Thunderbolt ports?
When I connect them, I get the following errors in dmesg, regardless of the cable I put between them :
[ x.y] ucsi_acpi USBC000:00: unknown error 0
[ x.y] ucsi_acpi USBC000:00: GET_CABLE_PROPERTY failed (-5)
Keen for any approach that might work, I’ve tried various cables.
