Griffin Technology, Inc. today posted beta version 1.5b1 of the iMate driver for their popular iMate USB to ADB adapter. The new version provides for more flexible control and improved support for the new PowerBook G3, Lombard models. The update provides a tighter integration between the iMate driver and the iMate Fiddler application. Performance and compatibility changes can now be made to the iMate on-the-fly. This makes tuning the performance of an ADB device much easier. Additional changes were also made that may improve reliability when awakening from sleep mode on the new PowerBook G3 "Lombard" models.
