We must connect a tablet to the network without wifi access, using usb cables. As far as I know there are OTG adapters to do this, but I'm interested in doing this without those. (Not all of the tablets are working with them)
We don't have a specific tablet model, I'm interested in Windows and Android tablet solutions as well. We don't need ineternet on the tablets, but we must reach our servers on the network.
We are thinking to do this because our customers won't create wifi access to us. The tablets will be used as biometric signature sources (and for some other applications later as well). There will be a (Windows) PC with an administrator and the tablet. The customer will use the tablet, the administrator will use the PC.
Some time ago I heard about virtual ethernet connections via USB. I'm not sure but they were able to create ethernet network using the usb ports. I wasn't able to find such a solution this time, much more virtualized usb connections via ethernet.
In the old days I heard about connecting PCs to each other via usb cables to play games as they were connected to the same network.
That's all what I know at this moment. Unfortunately all that I was able to find isn't sufficient to me. Most of the articles are talking about "reverse tethering" between android tablets and PCs. Unfortunately we aren't allowed to root the tablets due losing warranty, and still we would need OTG adapters.
I'm not sure but USB 3. is maybe a solution although the host PCs probably won't have such a port.
Is it possible to create such a connection? If the answer is yes, how? Am I wrong in my listed points maybe? Do you have any more information?
I really appreciate any help in the question!
