I'm banging my head on the wall here after realising the cause. I was using an Anker power adaptor, which supplies 60W in *total* to both ports on it - a USB-C port, and a USB-A port. The USB-A port consumes 15W, and the USB-C port is left with 45W. The USB-C hub - for example, the one I've got now consumes 18W from the 45W supplied - which leaves the laptop with 27W. My Thinkpad has a minimum required USB-C PD wattage of 45W - so that's why it wasn't working!

I've tested the hub and PD power adapter (Anker) on the same laptop on the Windows 10 partition. No luck. The PD chip in the laptop is recognised by Windows 10 though. I've ordered a replacement adapter (Anker), and hub, which should arrive tomorrow - I'll see how that goes. At this point, its either one of three things: - The laptop hardware. - The USB-C hub. - The Anker power adapter.

[gentoo-user] USB-C PD delivery & Lenovo USB-C hub.
Hello, I've got an Lenovo Thinkpad X270 laptop, with USB-C support. I ordered an Lenovo USB-C hub from Amazon the other day, and it arrived today. It [the hub] is recognised by the kernel for USB, but not for power delivery (PD), via ACPI. Oddly enough, when I plug the USB-C cable from the mains adapter directly to the USB-C port, ACPI recognises it fine - so I've narrowed it down to a driver issue. I've tried using the hub on my Thinkpad 13" on both Windows and Linux (Arch, specifically; Gentoo isn't on there at the moment.), and its recognised fine. Therefore I do not believe the hub *itself* is faulty. In terms of diagnostic information, I'm not sure where to start, so if anyone needs certain information to help with the issue, please let me know, and I'll do my best to email it. I'm running gentoo-sources-5.3.1 for the kernel. Any ideas? Thanks :-) -- Sincerely, Dom Rodriguez (shymega).
