There are 2 types of USB enabled devices. That is there are USB hosts and USB clients. Desktop Computer (and laptops) are USB Hosts. There are alos hubs, these appear as the host to all devices connected as a client, and as (a) client(s) to the host.
Each USB network can must have exactly one host. The host maages the the network and supplies power. All other devices must be clients.
Warning: You can damage host devices by having 2 hosts on a USB network
I can see 2 ways you could go about this:
- You can buy a USB bridge this is a device that looks like a USB A/A cable with a electronics box in the middle. the electronics box acts as 2 USB clients with a interface between them.
Here is an ebay link to one http://www.ebay.com/itm/USB2-0-PC-to...item3a779d5ed1 . I have no experiance with this type of product I just know they exist.
- Buy 2 USB to ethernet adapters then use a crossover cable to link the 2 computers. Then use TCP/UDP to talk between them.
There is USB OTG but this requires specialised hardware and is usually used in tablets/phones to allow one port to act as both client and host depending on the networkwork. this is set by a resitor in the cable.
