Are the ioremap and ucsi_acpi error related or is a separate report needed?The ioremap error is what causes ucsi_acpi to fail the probe call (-12 is "out of memory".)2. Do you know the reason for the ucsi_acpi error?the call to ioremap failed. Does this device really have a working typec connector?
Just to avoid misunderstandings, no device was connected to the laptop during my test.
But, from other boots, the Dell docking station TB16 kind of works with it, so I’d say the USB Type-C connector is working.
Does normal USB devices work with it?
Sorry for being ignorant, but could you please tell me what normal USB devices are?
Kind regards, Paul
