I'm resending this mail, it looks like it was filtered out or stuck in
moderation queue...

Meanwhile, I've found out it's a feature:

Hello,

After upgrading from R3.0 to R3.2-rc3, I am no longer able to hotplug
ExpressCard devices (e.g. USB 3.0 adapter). Is it a bug or feature?

When I connect adapter to running Qubes, nothing happens - it is not
detected, not reported by lspci, also there is nothing in dmesg.

When I boot Qubes with already connected adapter, it is properly
detected, attached to dom0, and works fine. But if I disconnect it,
it is still reported by lspci as connected.

As a workaround, I have to manually rescan PCI bus after connecting
adapter:
$ sudo sh -c 'echo 1 > /sys/bus/pci/rescan'

And manually remove it after disconnecting:
$ sudo sh -c 'echo 1 > /sys/bus/pci/devices/0000:05:00.0/remove'

It works, but it is not very handy :-(

Regards,
