That driver does not really do anything else except it queues a work that then actually initialises the UCSI interface. The probe() in that driver (ucsi_acpi) does not stay and wait for the initialisation to finish. Can you check are the USB Type-C devices appearing under /sys/class/typec faster then that? Also, if the driver is a module, can you check does it always take that long if you unload and the reload the module (ucsi_acpi.ko)? > Did I miss some other (needed) Kconfig option or is something missing in > my system's ACPI tables e.g.? There shouldn't be any dependencies that are missing, but it would not hurt to take a look at your acpi tables. Can you send acpidump? Though, I doubt there is anything missing from there either. > DMI: Dell Inc. Inspiron 15 5510/076F7Y, BIOS 2.4.1 11/05/2021 thanks, -- heikki
