Our messages crossed looks like. Yes this problem needs
to be fixed in stable. Reverting b89193e0b06f is definitely
an option, however I think we might see problems on other
devices. b89193e0b06f fixed problem on KWorld stick I have.

Mauro said b89193e0b06f is causing problems on some
USB ehci/xhci drivers.

Let's go ahead and revert it for now. I will work on
getting this reset_resume sorted out with the solution
I proposed in my previous email. I hope it is okay to
take you up un your offer to test.

thanks,
