Tienes que hacerles una pequeña historia para que el windows 7 admita drivers sin firmar pero luego va perfectamente, tengo el w7 64bits y el pad de la xbox conectado desde hace 10 meses y va perfecto.
Exactamente hice esto:
"Thought I'd post to say I got this working in Windows 7 x64 rtm heres how:
(You need to disable UAC for this to work)
download the 64bit driver:
http://www.mediafire.com/file/d54lk0gg0 ... driver.rar Run cmd.exe as administrator and type: CODE
Bcdedit.exe /set TESTSIGNING ON
Restart your computer.
Download Driver Signature Enforcement Overrider 1.3b:
http://www.ngohq.com/home.php?page=dseo Run the .exe and select "Sign a system file" and input the location of your .sys file like so:
"C:\Windows\System32\Drivers\xbcd.sys"
(With quotation marks) and restart your computer.
Now plug in your xbox pad and it should install correctly. If you have any problems try updating the driver manually and pointing it to the location of your file.
This works because in testing mode windows still requires a digital signiture but it does not need to be verified so we can create our own digital signiture and imprint it on the file.
Would be cool if someone could add rumble support too."
