USB Wireless adapter makes my WinXP "deep sleep"

Hello, All!

A few days ago, I have bought 54Mbps Wireless-G USB Adapter
http://www.eusso.com/Models/Wireless...GL2454-U2R.htm

The device itself works perfectly,
but now I have problem with my PC (AMD Athlon 3000+ , Windows XP SP2)

I often leave my PC turned on at home,
and use it from work with "Remote Desktop",
or other Remote Access Software (like "Real VNC").

I have a latest drivers for my device,
downloaded from EUSSO www.

So, I have noticed, that when I leave my PC online
after about 1 hour of inactivity, it falls in a "deep sleep"
and it is not possible to bring him back online,
except only the "reset" button, or turning "off" and then "on" again.

I have read many information in the Hardware Forums,
and many people said, that it is a "Sleep mode" or "Power saving"
problem.
OK, I have turned off all my "Power savings" (Turn off HDD, Monitor), but, nothing changes.
:-(

Well, at the other Forum, I have read, that, it is a software
problem, that do not support a "Sleep mode" or "Power saving".
OK, I have DEinstall all software coming in the downloaded archive -
"UGL2454-U2R_DrvUtly110.zip" (~11.9 mb)
Now I have installed only drivers (without software):
---
RT2500.CAT
RT2500.INF
RT2500.SYS
rt2500usb.cat
rt2500usb.inf
rt2500usb.sys
---
I found them in a "/XP" subfolder.

It's a pity, but nothing changes:
I have turned off ALL "Power saving" functions even in BIOS!!!
But, when I left my PC for some time,
I found him in a "lethargic sleep" when I returned back home.

Earlier, there was NOT any similar things!

Please, help me,
what I have to do, to make my PC working perfectly ?

Have you checked under the device manager and clicked directly on the device in there as there will be additional settings there. Make sure your bios is ACPI compliant as I have had all sorts of issues with USB WiFi crashing and not shutting down etc, and I have been told this can be an issue.

Good Luck
