Qubes and USB Ethernet adapter

[Swâmi Petaramesh]

Hi,

I have a new Asus laptop which comes with no integrated Ethernet, but an
USB Gigabit Ethernet adapter.

I wonder if this will be compatible with Qubes' Net VM, or if I will
need to allocate the complete USB controller to the net VM - which would
be extremely annoying to me...

Any clue appreciated.

Kind regards.

I've tried using an ASUS USB Ethernet adapter (with a Dell laptop in my case, but probably not relevant) without luck. I found that an USB Wifi Dongle worked better.

Hi,

Does anybody here have an idea about this ?

Some people have it working with USB wifi network adapters, so I don't
see why it wouldn't work with an Ethernet one. It would depend on driver
and/or firmware support being installed in the NetVM first, though,
although if you have access to another machine with network access and a
USB flash drive, you could manually copy over any missing drivers or
firmware. But I don't know if other people got it working using a USB VM
and doing pass-through for just that device, or if they had to allocate
the entire USB controller to the Net VM.

You could use qvm-usb to attach just the one USB device to sys-net.
This would have to be done after every boot (either manually or by a
script):

$ qvm-usb --attach sys-net sys-usb:<your device>

Or you could switch sys-firewall's netvm from sys-net to sys-usb -
which is possible because sys-usb's VM type is NetVM - and enable
Network Manager in sys-usb:

$ qvm-prefs --set sys-firewall netvm sys-usb
$ qvm-service --enable sys-usb network-manager # then restart sys-usb

Actually, run the qvm-prefs command _after_ restarting sys-usb

Uh. First time I tried this (after having performed a "qvm-usb -l" to
find the correct device), my sys-usb VM immediately crashed.

After restarting it however, when I try the same command again (device
ID in "qvm-usb -l" had changed), it fails with :

« ERROR: Device attach failed: /usr/lib/qubes/usb-import: line 51:
printf: write error: Invalid argument »

add it to sys-net, no?

If not delete your sys-usb.
don't even recreate it. and just to test find the right controller for the port you use,and add it to your sys-net.

[cooloutac]

oh but you prolly only have one controller. ya if i'm understanding correctly its already in sys-usb. so you should be adding it to sys-net to get network connection.

[cooloutac]

lol i just read "which would be extremely annoying to me" , sorry.
