[Feature] Bind Specific USB port to passthrough

[garandal245]

Feature Description

due to having to individually setup usb passthrough on a per device basis it fails for some devices that reboot into different modes(in this case my usecase is flashing an android device and on reboot it shows as a different devices with a different PID)

possibly some way such as adding a toggle on the devices usb passthrough section to passthrough on a per PID basis vs port/bus basis

Use-Case

for any devices that cycle PIDs in different modes(such as updating firmwares for some devices, flashing android via fastboot showing a different pid than usb debug etc) it allows to contentiously stay connected without having to re add the new PID possibly interuppting whatever you were doing if using a scripted tool

Proposed Implementation

possibly some way such as adding a radio button on the devices usb passthrough section to passthrough on a per PID basis vs port/bus basis

Notice

• I have checked the issue tracker and verified that this Feature Request has not been proposed before.
• I would like to help out implementing this feature

I'm also trying to do a firmware upgrade on a controller and having this exact problem.
Qemu does support usb port passthrough with -device usb-host,hostbus=3,hostport=1 so it should be just a matter of configuring the right arguments to it.

And regarding the UI elements -- it can be something like USB port matching device "XXXXXX"

I was able to update my cyclone 2 joystick. Take a look at #620
