Q: USB tethering

[Ulrich Windl]

Hi!

I had been asking this before: How hard will it be to use USB tethering
in Qubes OS?

Dom0 seems to recognize the interface, but I cannot assign it to any VM:

Mar 31 22:55:57 dom0 kernel: usb 2-10.2: new high-speed USB device
number 8 using xhci_hcd
Mar 31 22:55:57 dom0 kernel: usb 2-10.2: New USB device found,
idVendor=12d1, idProduct=108a, bcdDevice= 2.99

As in: use the USB connection to your phone as network interface? The
(standard) way I do it is to assign the USB controller to sys-net. The
rest kind of happened automatically after installing the respective
tools (I use an iDevice).

Unless you are using a desktop PC with a USB keyboard, this is also the
much safer approach (instead of having USB directly handled in dom0). If
you however use a USB keyboard things could get ugly and more planning
is needed.

Yep, wouldn't want this anywhere near dom0. Not that I trust my iDevice
substancially more, but I think you get the idea.

Well, you have no guarantee that no Huawei device is somewhere in your network path, and actually: I bought it because I would get more for less (as compared to Samsung for example)...
