Do you mean you want to disable USB2 capability to wake a sleeping system, don't you? If in "Device (USB2)" entry it have _PSW (Power State Wake) method, you will need to change it according to my modification.
Code:
Method (_PSW, 1, NotSerialized)
{
If (Arg0)
{
// Store (0x03, U4EN)
// Disable USB4 capability to wake a sleeping system
Store (0x00, U4EN)
}
Else
{
Store (0x00, U4EN)
}
}
Refer to arguments for _PSW:
Quote:
Arguments: (1)
Arg0 – An Integer containing a wake capability control
0 – Disable the device’s wake capabilities
1 – Enable the device’s wake capabilities
|
That is why I change both condition to execute the same thing. So that it always execute the same "Store" operation as if it is Arg0=0.
