Is there a way to wake upthe system with an USB device.
I've got the sconi which can control the PC wit a remote.

Thanks

This page mentions that there can be some settings in the
Device Manager, that might control waking from a USB Device.

At the hardware level, an essential ingredient needed to make
this work, is the setting of the USBPW12, USBPW34, USBPW56, and
USBPW78 headers on the motherboard. For the USB port where your
USB device is connected, the voltage should be set to "+5VSB".
By using +5VSB, the external USB device gets a source of power,
even when the computer is sleeping. That source of power is
necessary for the external USB device to wake up the rest of
the computer.

So, investigate how your USBPWxx power header is set. Then,
have a look around the Device Manager, and see if there is
an option to wake up a USB port.

I checked the Intel ICH5 datasheet, and in section 5.19.7
PDF page 212, it mentions a hypothetical "fax-modem" waking
the computer. So, the ICH5 appears to have taken into
consideration, waking from USB. (This file is a 7MB download).

I hope you have been reading about the "latchup failure" of
the ICH5 USB ports. I recommend against hot plugging USB
devices into P4P800/P4C800 motherboards with the ICH5 or ICH5R
Southbridge chips on them. As a workaround to this issue with
the Intel chipset, I recommend using a separate USB 2.0 PCI
card, to use with your USB device. A separate USB card will
reduce the risk of the destruction of the motherboard (which
can be repaired under warranty, but would take several weeks to
get a replacement motherboard.) The exposure is explained here,
in this link found by John S. :

Of course, if you use a separate USB card, then you will likely
need to enable this setting. The USB card would need to support
a standby powering option, for this to work. I don't know what
the correct terminology would be, in an advertisement for a
PCI card, for that feature to work (maybe "PCI-Bus Power
Management Interface specification" ? or PCI 2.2 revision,
as PME# and 3.3Vaux were added for waking functions ?).

Good luck,

At first. thank you very much.
I'll give your tips a try.
I'll come back!

Wow,
#
you're great it has worked for me :-).
The main setting was the +5VSB
for the USB Connectors!
Thanks again!
