problem in NDIS driver

OSR_Community_User · February 4, 2003, 5:40am

hi all
i have already posted this query in the list
but nobody responded
its very urgent for me

i need one urgent information regarding power management.

one thing i observed with Usb mouse( logitech) through USB BUS
analyser. when i put the system in standby mode, host issued
SET_FEATURE with REMOTE_WAKEUP_ENABLE.
After resuming the system, host
issued
CLEAR_FEATURE with REMOTE_WAKEUP_ENABLE.

Do i need to send IOCTL_INTERNAL_USB_SUBMIT_URB
with SET_FEATURE?
With my device, when i put system in standby, it is sending
request with sleep state. then Do i need to send any power irps?

Also i am getting Power request from NDIS( it is OID).
so i have to create power irp from the driver itself.
tell me the necessary details.
whether i have to create
the
power irp? and what request i have to send to lower level usb drivers.

thanks for ur answers

If you send a wait wake power irp to your pdo, the usb core will do the
set feature / clear feature for you automatically. By sending the wait
wake irp, you are arming your device to wake the machine out of a low
power state (< S0) so be sure you want to do this.
