Allow for configuring USB IDs

[jackislanding]

resolves #15

A new button is added to configure the USB Emulation.

USB descriptors can now be modified, and a successful configuration rebinds the USB Device.

USB Device ID Examples:

Before:

Shows the default JetKVM Descriptors

After:

Why would you allow for jetkvm to just take a random usb vid/pid? Those are assigned, not to be chosen randomly.

JetKVM doesn't have its own VID/PID, it uses the generic Linux Foundation Composite Device.

As for why? Some people want to hide the KVM. While I can't think of a legitimate reason for doing so, a lot of people ask for it. And besides, the KVM will always be detectable, even if someone fudges with the VID/PID

Many people have asked for the feature, and since I have knowledge of how the usb gadget framework works, I went ahead and took a crack at it.

I'm assuming it's a pretty valuable feature, and since the competition have it, I figured JetKVM should have a leg up.

I’d love to see a dropdown with preconfigured USB options, similar to what we did with EDID. With EDID for example, most users will not fully understand how it works, but they grasp the general concept and will try fiddle with available options. I suspect the same thing applies here.

@adamshiervani sounds good, what do you think about adding existing consumer devices and naming them as such?

Or should we have generic devices?

[adamshiervani]

I'd say let's just add 3-5 consumer devices that are commonly used. All other use cases get to customize their own.

Additionally, in the description of the modal, we could also link to some website where they can look their specific values.

@adamshiervani I'm ready to have this PR reviewed again

There is now a dropdown showing preconfigured options

When settting the config, a notifcation shows the user that the change has been successful

When selecting "custom", the button to manually set parameters appears:

Clicking the button shows the fields that can be set:

@adamshiervani The custom fields dialog also has a link to lookup the VID and PID.

It builds a query to the "the-sz.com" site to lookup IDs.

Below is an example url + query:

Looking great, I'll have a read through in a moment but you'll likely need to rebase this on dev as the config struct has moved along a fair bit since this PR started.

[adrianmeraz]

Understood, I'm unsure of how to rebase on another branch from my repo.

When trying to rebase, it just keeps going in an infinite loop of trying to merge conflicts.

[adrianmeraz]

Nevermind, it's been rebased. Check out PR #185

Closing in favour of #185
