mdmcpq.inf
usbser.sys
 
Copy mdmcpq.inf to c:\windows\inf
Copy usbser.sys to c:\windows\system32\drivers

Tips: For example, to open c:\windows\inf, just enter c:\windows\inf in the address bar (the address bar of IE input URL is the same as the address bar in my computer), and then enter c:\windows\inf.
