    Hey mine does not have “ASUS Android Composite ADB Interface”, but does show “Transformer Prime TF201″ in windows device manager. Do I update that driver or an I missing something??

    • hakim7489 says:

      mine too. the ‘Transformer Prime TF201′ is under ‘portable devices’ and there is no ‘other devices’….usb debugging is enabled and i am on ics…..any idea?

    • twadejr says:

      I had the same problem with the “ASUS Android Composite ADB Interface” not showing up. What worked for me is to make sure that the USB Debugging is on (Settings -> Developer Options -> USB Debugging), then goto the Device Manager and delete the “Transformer Prime TF201″ under “Portable Devices,” then scan for hardware changes and it then detects it as an ADB device and you can install the drivers from there. Good luck and hope that helped :)

  4. tor says:

    i keep trying to root but doesn’t work successfully all the apps that are supposed to install don’t and says failed; it reboots twice successfully but after that says no such directory or read only file…. Please HELPPPP!!!!

    • Rich says:

      It you already downloaded the 2.11 OTA update, it probably won’t work, lots of discussions about this on XDA and TransformerPrime Forums.

  5. Rich says:

    Has anyone tested this method post the 2.11 OTA update?

  6. Rich says:

    For the record and for those of you that have “NOT” accepted/downloaded the 2.11 OTA, this method works flawlessly. Was a piece of cake. If you had problems, go back through it slowly, if something fails, debug it and move on. It will work pre-2.11 OTA.

    Whats up Zedomax just got my TFP today I have not done the ICS udate yet figured I would first install the drivers than update ICS and than root.

    I have a problem where the name of the Device is supopse to show up as Asus Android Coposite ADB

    I am not getting this Iam just getting the Question mark so when I right click to update driver and choose from I go to desktop and It only allows for me to pick the unziped file but not the sub folder that you stated. It only gives me the option of two sub folders Amd64 and i386

    And when I choose neither will allow for me to press ok

    So I just pressed ok on the TransformerrPrimedriver folder. Once I did that it looked like it was working and than gave me an error about Parameters

    Dont understand why. I really appreciate your help and dont like to sound like noob but never had this problem. I was able to root my Evo and download the drivers for it without any problems on the same comp.

    I saw some people where posting the same issues on here. I have not done the OTA and know not to root before doing any of this.
