This article discusses Logitech Systems where users encounter challenges with their Apple or Surface Pro devices, either in projecting images on the screen or accessing system Mic, Cam, and Speaker drivers from the native system. This situation applies to both Zoom, Teams, and BYOD modes, whether operating on Android (Rally Bar) or a Windows PC hosting the conferencing platform.
The initial step when a device is unresponsive to a BYOD Logi Swytch connection (purple cable) is to check the system wiring, ensuring all cables are connected to their correct ports. Please refer to the Logitech wiring diagrams to confirm that the devices in your area are wired according to Logitech's standards and the equipment involved: Logitech Wiring Diagrams
Next, to maximize the likelihood of these devices functioning properly with the system, follow the checklist below:
1. Ensure the Logitech equipment is updated to the latest firmware and software. This can be done locally through the admin settings on the TAP or via your Logitech Sync portal if the room is associated with your organization. Additionally, updates can be initiated from your conferencing platform admin page, such as the Zoom admin portal or Teams Admin Center (TAC).
2. Update the concerned laptop to its latest system firmware, whether through Windows Updates or Apple's OS updates. Pay close attention to any additional graphics card updates that may be available through other applications like the NVIDIA app.
3. Download and install the latest Display Link Drivers from Synaptics, which can assist in resolving certain issues related to video sharing over USB connections (note: specific versions are available for Apple vs Windows): Display Link Drivers
4. If your laptop is operating at an unusual resolution or refresh rate, this could disrupt projection. Reverting to a resolution of 1080p at a 60hz refresh rate in your advanced display options may improve performance. Additionally, not all USB ports are the same. Ensure the port in use is USB 3.0 or higher, supports display functionality, and is not Thunderbolt 5 or above. Thunderbolt 3 and 4 ports are confirmed as compatible.
Note: If experiencing mixed results, such as getting the image on screen but missing drivers - or vice versa, you may still need to utilize HDMI input into the TAP in combination with the USB connection. Our experience has indicated that certain processor chipsets are not compatible with a single Swytch connection without other options. Successful outcomes have been noted using the Apple Brand USB-C Digital AV Multiport Adapter for both Apple and Surface Pro laptops as a workaround. The only caveat is that the standard USB Swytch cable (2-pronged purple USB cable) does not fit into the Apple Multiport adapter. In this case, simply substitute the Swytch cable with any compatible USB-A to USB-C cable that is USB 3.0 or higher. The standard cable connects to the Swytch Hub Extender device via USB A (3.0) or USB B Micro (3.0). Both connections can be replaced with a single USB A (3.0) to USB C cable for the laptop connection.
