I bought Ralink 802.11n usb wireless adapter from ebay. When i plugged it in my pc it shows error
This device cannot start. (Code 10)
{Operation failed}
The requested operation was unsuccessful..
Then i plugged it in usb 2.0
Then the error changed to
This device cannot start (code 10)
The usb returned an invalid serial number string descriptor.
But when i plugged it in my laptop and disabled internal wireless card. It worked fine...
I tried everything drivers .. installed windows again.. everything.. still same problem..
