The hashes are all SHA-256 truncated to 15 bits; the 16th bit is set to whether the device is removable (1 if removable).
#### `version`
This is the version of the hardware ID. It is set to `0` for all implementations I'm aware of.
#### `nInstances`
This is an array of 9 counts of instances of hardware per type of hardware. The types are, in order (by 0-based index):
