Hi,
We have designed and implemented a AVS driver on top of the USB driver
stack. Problems with the power management occured. The function
KSDEVICE_DISPATCH::SetPower is currently used to get the power switching
events from the AVS model.
During power up process we do have the following problem:
If we access the USB driver in the context of the SetPower function we
get an error message 0x8000000F STATUS_DEVICE_POWER_OFF.
Question:
Which function can be used to access the USB driver API in a secure way
during wakeup from a sleep state?
How to solve this issue?
Thanks,
Micha
