Hence in some sense the PCMCIA card can be used. However this
requires manually killing ehci_hcd that is very inconvenient, because
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.

And the device starts working.
BTW: note that there is in fact no cable at all. Everything is self
contained in the PCMCIA card
Hope this helps

PS:
Two notices:
1) I found an extra long thread about ehci_hcd related problems at
https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/88746,
but I do not know if it is related.
For sure I tried disabling autosuspend features in usb in my 2.6.22
kernel via the dev/sys/bus/usb interface and that did not help.
2) Also there are notes about ehci_hcd preventing some devices from
working at http://article.gmane.org/gmane.linux.usb.devel/60461
