These will almost always show up as a Microsoft HID device, though can appear as other trackpads as well. These will show up as a PS2 Compliant Trackpad, as well under USB when we switch our connection view to Device by Connection I2C While you can use the trackpad in either mode, SMBus generally provides better gesture support and accuracy. Synaptics devices will show up under both PS2 under Synaptics PS2 device/ Synaptics Pointing Device and PCI as Synaptics SMBus DriverĪs you can see, we get 2 Synaptics devices in the left image, however if we take a closer look we'll see the top device is PS2, while the bottom one is SMBus.These will show up as a straight PCI device such as Synaptics SMBus Driver or ELAN SMBus Driver This will clarify whether it's over PS2, I2C, SMBus, USB, etcĭepending on the device, it may show up under multiple names and connections. To view the exact connection type of the device, select the pointer device then enter View -> Device by Connection. You can find these devices under the following: # Keyboard, Trackpad and Touchscreen Connection Type DeviceManagerĪIDA64 unfortunately doesn't provide any useful info regarding pointer devices, so we recommend using DeviceManager for this. This means trying to detect the exact chipset is a bit more difficult Note: Intel SOC based CPUs will have the chipset and other features already on the same die instead of being dedicated chips.However we'll show you both methods for obtaining hardware specs.
Keyboard, Trackpad and Touchscreen Connection Typeĭue to the easier to use GUI, we recommend downloading AIDA64 and running this as it's much easier to grab specs.Getting started with ACPI (opens new window).
