Connecting Samsung GALAXY Tab 10.1 via adb on Ubuntu

3 Comments

At Google I/O, the attendee brought back Samsung GALAXY Tab 10.1. I had a chance to touch it.

At first I tried to connect it to Windows 7 PC by USB cable. But it said failed to install USB driver. Someone said Samsung special develop tool includes the USB driver. But I don’t want install such kind of big software. I just want USB driver for GLAXY Tab. I thought NexusOne’s USB driver might work with small change of configuration file, it didn’t get well.
