USB handled in dom0: no way to use it for VM networking USB handled in sys-net: should be easily accessible using the same NetworkManager icon USB handled in sys-usb: possible to use it after some configuration: One of: - assign the device to sys-net using qvm-usb - enable NetworkManager sys-usb (in "services" tab in sys-usb settings) and assign it as a netvm for sys-firewall - -- Best Regards, Marek Marczykowski-Górecki Invisible Things Lab A: Because it messes up the order in which people normally read text.

Hi Neil, In my experience, USB network dongle (either wifi or copper), do not seem to work outside the the USB cube. I tried to assign the USB network adapter to sys-net, but it failed Since then, I installed 3.2rc1 with the option of USB and networking in one qube. You Could try it, but I think you'd need to prevent the network drivers from loading in the USB qube somehow.

Re: [qubes-users] Question on creating USB qube
What that option means is to not actually create a new "sys-usb" qube to handle the USB controllers, but rather use the already existing "sys-net" qube to handle the USB controllers. Since the "sys-net" qube already handles networking, the option states "both networking and USB devices". Having a "sys-usb" qube on will probably consume a small amount of additional RAM memory, and having "sys-net" handle more things will probably open an hypothetical probability of something going wrong in an hypothetical future. Come to think about it, I have another question: how different would be to use USB network cards in the three different scenarios (USB handled by dom0, sys-net and sys-usb)? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

[qubes-users] Question on creating USB qube
I am installing QUBES 3.2 to a new laptop. With the 1st option: [X] "Create a USB qube holding all USB controllers (sys-usb) [experimental]" There is then a 2nd option underneath: [ ] "Use sys-net qube for both networking and USB devices" Is it recommended to check the box for the 2nd option or not? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
