Sleep during download

Hi,

We develop a USB network device driver based on MBN API for Wndows 7. When
downloading something, the Windows 7 (7600) machine may still go to sleep in
the middle of the download. If you make the same download through a fixed
Ethernet cable or WiFi, the machine does not go to sleep until the download
is complete.

How can we control this behaviour from our NDIS MBN driver?

Thanks,

/ Hannes.

networking activity, no matter the phy, should not affect the machine's idle
state. perhaps over ethernet or wifi it is just much faster than your MBN
device so it completes before the idle timer fires

Our tests were executed with very large file transfers, and our customers see
the same thing - the PC may go to sleep while downloading over our network
device, but not over other connections. We set the sleep time to 1 minute to
test this.

So you are saying that Windows should always go to sleep, regardless of
ongoing downloads etc?

Do you think it would be a good idea for our driver to veto the system sleep
event in order to delay the sleep until the download is complete (i.e. by
measuring network activity in some way) ?

Thanks,

/ Hannes.
