Bootcamp - Apple SPI Device driver missing - Touchpad/Keyboard don't work
After doing some more messing around (and a bunch of trial-and-error) I was able to identify and manually install the keyboard and trackpad drivers!
To manually install the keyboard and trackpad drivers to their respective SPI Device entries in Device Manager, I clicked 'Update Driver'&gt;'Browse my computer...'&gt;'Let me pick from a list...'&gt;'Human Interface Devices'&gt;'Apple Inc.'&gt;Apple SPI Keyboard/Trackpad'
On my 2016 MacBookPro touch bar, this is how the Apple SPI Devices correlated to the drivers, based on the value in Properties&gt;Details&gt;Property: Hardware Ids:
SPI\VID_05ac&amp;PID_027b&amp;MI_01 (SPI Bus Location 1) - Apple SPI Keyboard

SPI\VID_05ac&amp;PID_027b&amp;MI_02 (SPI Bus Location 2) - Apple SPI Trackpad

However, I still need to determine which drivers go with the remaining 3 unknown devices. Their hardware IDs are:
SPI\VID_05ac&amp;PID_027b&amp;MI_00 (SPI Bus Location 0)

SPI\VID_05ac&amp;PID_027b&amp;MI_03 (SPI Bus Location 3)

SPI\VID_05ac&amp;PID_027b&amp;MI_04 (SPI Bus Location 4)

Does anyone have any ideas as to what these 3 hardware devices are?
