EXC80H60 is used in Ambu aBox2 with ACPI _HID "EGA00001".

Snippet of from "apcidump -b; iasl ssdt2.dat" on target:

Device (TPL2)
{
Name (HID2, Zero)
Name (_HID, "EGA00001") // _HID: Hardware ID
Name (_CID, "PNP0C50" /* HID Protocol Device (I2C bus) */)
// _CID: Compatible ID
Name (_S0W, 0x04) // _S0W: S0 Device Wake State
Name (SBFB, ResourceTemplate ()
