Android: Install USB drivers for HP Touchpad

If you have a HP Touchpad running CyanogenMod Android, you can use it to develop and test applications on the native device. But before you can use the tools from the Android SDK on a Windows PC, you have to install the USB drivers.

The Android SDK provides USB drivers for Windows in <sdk-directory>/extras/google/usb-drivers. But those drivers don't include the needed information to identifiy a CyanogenMod Android. CyanogenMod has a patched android_winusb.inf file and the instructions on how to install it available in their wiki.

The patched driver information file does not contain information for the HP Touchpad. You have to patch the patched INF file again for the Touchpad.

So here are the steps needed to connect the Touchpad to a Windows PC to start developing/debugging:


1. Turn on MTP, which is disabled by default, on the Touchpad.

Go to Settings -> Storage -> click on the three small squares in the upper right corner -> USB computer connection -> enable Media Device (MTP)

2. Add HP Touchpad Vendor and Product IDs to the INF file

Edit the android_winusb.inf either from the CyanodgenMod wiki or the original file from the Android SDK. Add these lines at the end of the sections for [Google.NTx86] and [Google.NTamd64].

; HP TouchPad
%SingleAdbInterface%    = USB_Install, USB\VID_0BB4&PID_6860&REV_0227&MI_01
%CompositeAdbInterface% = USB_Install, USB\VID_0BB4&PID_6860&MI_01

3. Update driver in Windows Device Manager

Open the Device Manager in Windows, selection the unknown USB device and update drivers. Select the android_winusb.inf file you just modified.

4) Reboot Touchpad
