*Qubes version*


*Affected component(s) or functionality*

02.00.0: Realtek PCI Express Card Reader RTL8411B vs.

02.00.1: Realtek PCI Express Gigabit Ethernet controller RTL8111/8168/8411


*Steps to reproduce the behaviour

1. From sys-usb Qube Settings (or any other qube), section Devices, attach device 02.00.0 (card reader).

2. Start sys-usb (or other qube).

*Expected or desired behaviour*

The VM will start and card reader device is available.

*Actual behaviour*

The VM won't start. An error message appears: "qrexec-daemon startup failed: Connection to tthe VM failed".

*General notes

The same problem occurred right after installation with my Ethernet controller in sys-net. In that case I managed to get sys-net started (with my Ethernet controller working) by following suggestions in issue #1393 <https://github.com/QubesOS/qubes-issues/issues/1393>. Assign both Ethernet controller and card reader to sys-net did not work, but removing card reader did (/echo -n "1" > /sys/bus/pci/devices/0000:02:00.0/remove/).

I thought I could do vice versa to get card reader working, but in this case I had no luck. I tried in vain:

- removing Ethernet controller (/echo -n "1" > /sys/bus/pci/devices/0000:02:00.1/remove/).

- attach card reader with no-strict-reset (/qvm-pci a work dom0:02.00.0 --persistent -o no-strict-reset=true/)

- attach it with permissive mode (/qvm-pci a work ///dom0:02.00.0/ --persistent -o no-strict-reset=true/).
