Dear Linux folks, Linux 4.17-rc5 shows the error below on the Dell XPS 13 9370 with Debian Sid/unstable. ``` […] [0.440240] usb: port power management may be unreliable [0.441358] usbcore: registered new interface driver usb-storage [0.441367] usbcore: registered new interface driver usbserial_generic [0.441369] usbserial: USB Serial support registered for generic [0.441383] ioremap error for 0x3f799000-0x3f79a000, requested 0x2, got 0x0 [0.441518] ucsi_acpi: probe of USBC000:00 failed with error -12 […] ``` 1.

If you plug a USB typeC device into this port, does it work? A docking station is a little bit "different" in that it usually uses the PCIe connection, not the USB connectors. Or at least that's how my Dell docking station works last time I tried it[1] thanks, greg k-h [1] When the power supply for the docking station is bigger than the laptop's power supply, you begin to wonder what is in that thing and stop using it after a while... -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I think Dell always supplies the ACPI device node for UCSI in their acpi tables. The _STA method in that device node is then used to inform the OS if the interface exists or not. The return value for _STA comes probable from BIOS, so this is most likely a BIOS problem.

Paul,
The team that sustains platforms does perform Linux testing, but it's not
centered around latest upstream kernel and it's also functionally based (not
reviewing dmesg for new kernel errors) so there are changes in
expectations (viewed as regressions) as you find from time to time.

Heikki, I confirmed with internal team that UCSI is implemented on XPS 9370 and was confirmed to be working properly with Windows 10 RS2+. The reason that _STA is responding on this device node now but wasn't previously is it wasn't exposed in Linux until 4.16 when the Win 10 RS2 OSI string started to respond. Intel should internally have some XPS 9370 you can remotely access if you would like to poke around ACPI tables some. > > Please note that UCSI will only supply status information to the > operating system, so the USB Type-C ports will function normally even > without it.

Some examples: There are Dell docking stations with Thunderbolt (TB16) or without (WD15). You can also pick up little dongles for ethernet or combo dongles for ethernet/VGA/HDMI/etc. Anything non-Thunderbolt would satisfy what Greg was looking for. > > > > thanks, > > > > greg k-h > > > > [1] When the power supply for the docking station is bigger than the > > laptop's power supply, you begin to wonder what is in that thing and > > stop using it after a while... Mostly to satisfy letting the docking station work with beefier machines and still deliver power up to what USB PD will negotiate. I think they can actually run with smaller power supplies but you will need something "a little" bigger than regular system power supply to power the dock and system both. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Given the date of my docking station (2+ years old), I would be _amazed_ if it could do USB PD. But I should go try it, my existing Dell laptop doesn't support that, but I have an Acer here, along with some chromebooks that do. I guess I need to go get the latest Dell laptop, "just to test" with :) thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I will try get access to XPS 9370, but with the acpi tables, if somebody could just send me acpidump, that would be enough: % acpidump -o xps9370_acpi.dump > > Please note that UCSI will only supply status information to the > > operating system, so the USB Type-C ports will function normally even > > without it.
