Windows 7: Wifi Dongle prevents Sleep State in Win7

Wifi Dongle prevents Sleep State in Win7

Hi,
I am new here and totally desperate. I narrowed down the problem to the fact that USB flash drives and WiFi dongles (these devices have been tested sofar) prevent the pc to enter sleep state (energy saving).
When I detach the dongle or the drive sleep state immediately works fine, with the dongle/drive attached the screen turns black but all fans keep on working (psu, cpu, etc).
What makes the whole thing even "funnier" is that after boot and automatic connection to the router I can access sleep mode without problems. It works fine and I can repeat that numerous times UNTIL I open my internet browser or check my emails in my email client. At that point sleep mode does not work anymore - or lets say - works as described above. I have to restart the pc again to be able to enter proper sleep mode until I actively start using the internet again.
I changed all energy saving options imaginable, played with powercfg readouts, edit registry regarding IPv6, etc etc.

Drivers are up to date, BIOS is updated, BIOS settings are optimized defaults, I tried all USB ports, asmedia driven, intel driven, USB2.0, USB 3.0, I even tried another dongle from Ralink - same situation. As mentioned, same happens with flash drives.

Any ideas?

Edit: all necessary Specs can be found in my system specs

Look at the power management tab of the usb device properties, there is a box that says,... Allow the computer to turn off this device to save power.

Hi,
Thanks for your reply. As i said i tried all energy saving options back and forth several times. The option you mentioned as well. Didnt help. I have another suspect - aisuite ii which is known for its bugs and i believe that before the first installation of it things worked fine. I have it uninstalled - didnt help but i suspect that this crappy program has left some traces. But i am still reluctant to test this with a complete new installation of the os...

Ideas welcome :-)

I even thought about selective suspend of usb but this is beyond my capabilities i suppose.
Edit: just realized what you meant is selective suspend. My win is in german. With selective suspend i was considering an approach closer to the hardware. Anyhow, it did not work.

Just to let you know. it was something with the drivers. Either corrupt or conflict. After reinstalling Windows and all the other software I use, while omitting Asus AI Suite II everything is fine with sleep mode.

LM-001 wifi dongle
Hi Just installed 7 on an ancient IBM R31 laptop which barely ran XP and it works great! No DVD drive so I installed via a flash drive on a USB 1 port(!). Problem is that I cannot get on the internet because I can't get my LM-001 wifi dongle to work. Tried XP and vista drivers, no errors...
