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).
