THIS IS FOR A MAC ONLY!

Here’s what you need to do to make your phone visible to adb:

1. Open terminal (Applications/Utilities/Terminal)
2. cd /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/IOUSBCompositeDriver.kext/Contents
3. sudo nano Info.plist (or vi, or emacs, or whatever console editor you prefer)
4. Copy the IOUSBComposite section (from to )
5. Paste the section in at line 66 (right after where it appears) so you have 2 copies in the file
6. Change the bDeviceSubClass value from 0 to 2
7. Change the key name from IOUSBComposite to GW620

The end result should look something like this:

                    GW620
                    
                            CFBundleIdentifier
                            com.apple.driver.AppleUSBComposite
                            IOClass
                            IOUSBCompositeDriver
                            IOProviderClass
                            IOUSBDevice
                            bDeviceClass
                            0
                            bDeviceSubClass
                            2

8. sudo diskutil repairpermissions / and let it finish
9. sudo touch /System/Library/Extensions and wait a few mins for the extension reindexing to finish
10. adb devices should now see your phone

Note, this is VERY kludgy, and will probably break every time OSX updates itself, but it works. I can finally stop rebooting every time I want to work on the phone! :D
