In some subsystems, notably the BAS subsystem managing 85 devices contained in the base of the Surface Book 3 and the KIP subsystem 86 managing type-cover devices in the Surface Pro 8 and Surface Pro X, 87 devices can be (hot-)removed. Hub devices and drivers are required to 88 manage these subdevices. 89 90 Devices managed via these hubs are: 91 - Battery/AC devices (Surface Book 3). 92 - HID input devices (7th-generation and later models with detachable 93 input devices). 94 95 Select M (recommended) or Y here if you want support for the above 96 mentioned devices on the corresponding Surface models. Without this 97 module, the respective devices mentioned above will not be instantiated 98 and thus any functionality provided by them will be missing, even when 99 drivers for these devices are present. This module only provides the 100 respective subsystem hubs. Both drivers and device specification (e.g. 101 via the Surface Aggregator Registry) for these devices still need to be 102 selected via other options. 103 |
