> 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

> When I boot Qubes with already connected adapter, it is properly

> As a workaround, I have to manually rescan PCI bus after connecting

> $ 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 :-(
