I followed all the steps here: http://developer.android.com/sdk/win-usb.html
but reach a problem when I get to the end of this part:
Connect your Android-powered device to your computer's USB port.
Right-click on My Computer from your desktop or Windows Explorer, and select Manage.
Select Device Manager in the left pane.
Locate and expand Android Phone in the right pane.
Right-click Android Composite ADB Interface and select Update Driver. This will launch the Hardware Update Wizard.
Select Install from a list or specific location and click Next.
Select Search for the best driver in these locations; un-check Search removable media; and check Include this location in the search.
Click Browse and locate the USB driver folder. (The Google USB Driver is located in <sdk>\google-usb_driver\.)
Click Next to upgrade the driver.
When I click 'Next' it doesn't install anything, it gives me some error that is so general it doesn't tell me anything... how do I actually install the driver? thanks
