re-moving the card
Complete dmesg is attached. OK, the "60sec" delay is when xhci_hcd gives away its attempts.
I am not knowlegeable of the kernel at all but it is my impression that because of the
card presence detection there is no way to prevent that. But, if I get it right, now when I
pluging the card+USB disk in it into the computer before those "60sec" it gets detected,
so my problem is gone (xhci cancels the timeout because a "new card" was popped in with a "new"
device.
So, although I am now not sure whether I need your last patch, for the practical purpose that
I want to plugin a new card with a device into my computer, it works now. (added Sarah Sharp
into CC: just to make her aware of this scenario, no problem with xhci_hcd in my eyes)
;)
