The only quirk specific code I can find in Linux's kernel for XHCI is this: http://lxr.free-electrons.com/source/drivers/usb/host/pci-quirks.c I believe I have one of the SBxxx AMD chipsets, though I can't recall which one. I don't see anything in there referring to my PCI IDs, unless I'm looking at the wrong outputs in pciconf -lv. I see one quirk in particular regarding power management but that seems to be more about stability rather than speed. I'm sure I'm missing something.
