I've got the Samsung brand (not a clone) external Keyboard/Dock for my Galaxy Tab WIFI only runing Android 2.2.1. I like it, except - I find that I must reboot the TAB each time I want to use the keyboard! When I drop the Tab into the dock, it makes a sound like it knows its been plugged in, but the keys won't work until I reboot the TAB while sitting in the dock. Any help greatly appreciated.
