My HID device has an interrupt endpoint that is normally polled every 5 ms. I notice that after 60 seconds of inactivity, the pole rate drops down to 2 or 3 times per second.
Device and driver characteristics:
-
Hid device with pen/tablet usage with a maximum of two touch points.
-
The USB device can be configured as self/bus powered. I’ll make sure that the device descriptor advertises the Power attributes accordingly.
-
KMDF Hid mini driver.
-
Device Manger power settings tab grays out the option to turn ON/OFF idle settings. ?Allow the Computer to turn off this device to save power?.
I?d like to
-
Enable the idle settings in Device Manger power settings tab, so that the user can modify it.
-
Set the initial default value to false, meaning ?. Do not Allow the Computer to turn off this device to save power?.
thanks,
