usb 2.0 cardbus hangs laptop (ehci problem)

Hi,
I have just upgraded to debian testing (latest kernel) on my old
laptop. I hoped the newest kernel would solve this issue, but it's still
here.
I am trying to use a pcmcia (cardbus) usb 2.0 card.
It's found & usb driver are loaded. (see next). But when I connect an
usb2.0 device (such as dvb-t card) the laptop hangs until I remove the
card.
Googling I've found a similar problem, and it pointed to the ehci.
disabling ehci (removing the kernel driver after plugging in the card)
solves the hangs. But this way I have a usb1.1 and I need a 2.0 for the tv
card.
any idea?
these are the log files:
