Griffin Technology Inc., has released version 1.8 of their iMate driver for the iMate USB to ADB device. The iMate allows legacy Apple Desktop Bus (ADB) devices to be used on USB equipped Macs. According to Griffin Technology:
The new version of the iMate driver also supports more devices and should be more stable for some other devices. A few additional hardware protection dongles are supported with this version of the iMate. Also the Xrite Colortron II and Kernel Productions JoyPort now work properly without making modifications to the iMate driver. A problem with Kensington trackballs where the trackball would sometimes lose it's custom buttons after a period of time is resolved in this version. Also this version of the iMate driver has some other small fixes like an idle problem that would sometimes occur with certain System and USB versions.
The iMate driver now comes with a control panel to control settings of the iMate hardware and iMate driver. This allows users to easily change settings like the ADB Polling speed to optimize performance or improve compatibility.
The iMate universal USB to ADB adapter allows hundreds of existing ADB devices to be used with iMacs, Lombard PowerBooks G3s, G4s, and iBooks. It supports a wide range of devices including, mice, keyboards, trackballs, trackpads, joysticks, hardware protection dongles, keyboards, bar code readers, drawing tablets, AppleVision/ColorSync/Studio Display monitors, special education and handicap devices, and many other specialized devices.
Version 1.8 of the iMate driver can be found at the Griffin Technology web site, and is free for users of the iMate USB to ADB adapter. You can find more information on the iMate and the iMate driver software at the Griffin Technology web site.
