Lenovo T450 slow USB after resume from suspend

I'm having a weird issue with a newly installed instance of Arch on my Thinkpad (my first Arch installation actually!)

Suspending works perfectly but when I resume from suspend it takes a couple minutes before the laptop realises that it has USB devices and lets me access them. If I try run lsusb after resuming it hangs for a period of time before returning at the same time the USB devices come back online. The touchpad, keyboard, audio, etc all work though.. If I do lspci immediately after suspend I can see two xHCI controllers.

Any idea of what could be causing it?
