I had been using Barnacle with my Motorola Droid (upgraded to Froyo), and it connected to my iPad and laptop without any issues. Just tried it the other day, and I get a message stating "Baranacle requires 'su' to access the hardware! Please, make sure you have root access". The phone is obviously rooted (easy root), since I had been using Barnacle before. Any reason why it's not working now? what exactly IS 'su'?
