Question : Problem: Usb device continuously unplug and plug

When I connect wireless usb adapter with long length usb cable (5m).
It continuously plug and unplug. So I try to unplug and plug it until windows detect it as usb 1.1 device. After that it's stable.

How can I use this device with long length cable without trying to unplug and plug it until windows detect it as usb 1.1 device? Can I force some usb 2.0 port down to usb 1.1 to solve this problem ?

Thanks for your help, coredatarecovery
But there are no option about usb version on the device properties dialog.
My device is Edimax EW-7318USg

I have update driver to latest version. And now the problem go away.
