if at the same time one needs to use a high-speed storage device, then
this gets really bad.
I would like to know if this issue had already been reported and
maybe solved and alternatively if there is some way to _selectively_
ban ehci_hcd from attaching to a single hub, rather than disabling it
completely.
Please provide "lspci -v" with and without the card and "dmesg" before
and after you plug in the card.

to detail it better: with -v in the lspci
