Can I have a usb switcher to change between two camera while still using photon

According to the FTC Docs, you can use a USB switcher to switch between two cameras while using Photon, but it's not a straightforward process.

The documentation states that the SDK can accommodate two portals, each with full features including AprilTag and Color processors, and even switchable cameras. However, it's recommended to use a USB hub to connect the cameras to the Control Hub, and the USB switcher should be compatible with the hub.

It's also important to note that the USB switcher should be able to handle the bandwidth requirements of the cameras, and the switcher's latency should be minimal to avoid affecting the performance of the vision system.

Additionally, you'll need to configure the USB switcher to work with the Photon system, which may require some advanced setup and configuration.

It's recommended to consult the FTC Docs and the AprilTag Switchable Cameras sample program for more information on how to set up and use a USB switcher with Photon.

Rule G10 of the Competition Manual states that teams are allowed to use USB switches, but they must be used in accordance with the rules and guidelines set forth in the manual.

Please note that the rules and guidelines may change, and it's always best to check the official Competition Manual for the most up-to-date information.
