Windows 7 & Alpha Wireless Usb device Error

Hi eveyone!!

Ok iam having problems with windows 7 and my wireless usb alpha divice
well what it does is this everything is working ok once i start up my desktop
computer everything is working fine it reads my wireless but after a while it just
turn off my wireless alpha anntena all my wireless conections gone & when i restart i get this USB_Code_Error then the computer restarts i login and everything goes back to normal at least for a while until it happens again any ideas?

does this happen while you are using the computer? or after it has been idle for awhile?

I will say yes i have the latest drivers for the alpha wireless
and 2nd i will say yes both this happen while iam in internet too
and if i let my computer been idle for awhile so is a pain just now i had to restart
the my computer so i can be here posting this and it get's really frustrating
after awhile i thought it was the OS and i reinstall it but it did nothing same problem.
i have try other Usb ports but same problem. and i have many usb stuff:

keyboard
mouse
joypad
speakers

They all work fine except usb alpha wireless.
and it can be the anntena cause it works just fine with xp.

here are a couple of things you can try. i dont know if they will solve the problem or not:

USB port may stop working after you remove or insert a USB device

USB devices that are connected to a computer may not work after the computer is idle for more than one hour Windows 7 or in Windows Server 2008 R2

Nop this didn't work either anyone knows how this problem!!!
