I am just posting this because I am not sure if everyone knows this? Maybe they do. I just havnt seen it mentioned, and I dont think I saw this in a manual, I just tried it being an IT guy. The Redline HMI has a nice web interface where you can do quite a few things, including managing the files on the HMI instead of having to use the USB method. I have in fact never used the USB method and just used this. It also has this ‘Camera Feed’ option which is interesting. I wonder if I could hook up a USB camera to it? Just sharing.
How do I find this page?
You have to figure out the IP address of your HMI Redline controller on your network. You should be able to see this on your Internet / WIFI Router in the admin screens in a section somewhere where it talks about connected devices or clients and you can identify it if your router shows you information about the client (see the screen shot for what mine shows). Also, most nternet/wifi routers will assign a dynamic IP to your HMI which means it could change after you find it. Most routers offer a way to bind it to an IP that doesnt change, which is the way to go. In an internet/wifi router, sometimes settings like that are found under the ‘DHCP’ section if there is one, or sometimes you can just find the client, and check a box that says something like ‘static IP’, ‘bind’ or something like that. You could google/AI about the model of router you have to figure that out.
And actually there is an easier way - Go to the HMI screen, config menu, network and it shows you the IP (see screen shot), then you just go to your PC (or phone because its just a web page) and go to http://192.168.1.217/ (which is my IP) and your there. Dont laugh at my network name 
You can indeed connect a webcam… I saw some info on a few known ones that work, it was somewhere here in the forums (I’ll see if I can find it again).
UPDATE: Here’s a thread: Does the Redline Controller already support a Camera?
You’ll want to use a powered usb hub with cameras as they suck too much power from the hmi 
This is what happens if you act like an ID10T when selecting which port to connect to.
