Samsung Galaxy Tab 7" Plus -- adb drivers
The current best, known solution is to use "adbWireless" to connect the device with one's computer over a network. Be careful to connect both devices to the same network.

If you do not have access to a wireless network, the .apk can be transferred in harddrive mode after exporting the project from eclipse. However, this route does not allow use of adb for logging, debug mode, or any other tools. (See application "aLogcat" if logcat logs are wanted)

If anyone finds other solutions, please edit this answer.
