I realized with Win 7 that if the Express Card with the two USB 3.0 ports has an external drive
connected, its removal gets "always" detected. Probably because USB is polling for the disk and
realizes that is is gone?

Second observation is that in Device manager if I open the USB controllers list, I see for
this card a USB HUB and a USB controller (two lines in the listig). If I remove the card
the listing doesn't get updated. When I open the ROOT HUB properties, on the General tab
is claimed that it is working well and the system does not realize the card is unplugged
a long while already. But, if I open properties of the HOST CONTROLLER, it I think updates
the "General tab" and says something about code 45. And after closing tgis HOST CONTROLLER
window, the Device manager windows gets refreshed and the two lines related to the card
disappear.



I just tried something similar under linux, with all the patches I accumulated for 3.4-rc3
and posted in my previous emails. It seems linux flips some value so on every second card
removal it really does realize it was just unplugged.
