I've snipped so much because I don't know enough to comment on your details, but I did learn one thing during my struggle: the xhci driver is under heavy development, and bugs are being added and fixed almost every day. Based on my experience, I think that trying different versions of the kernel (maybe even vanilla-kernel?) would give you more useful info than switching compiler/use flags, etc. <kernel gossip> Sarah Sharp was xhci maintainer during my troubles, and I was sad to learn that she resigned because of Linus's foul and abusive (and unrepentant) behavior towards other kernel devs. </kernel gossip>
