USB HUB for Improved ECU Connection: CMC 9000, 8500eSBT, 8500e, 8500 and 8000
Some computer systems have problems with USB compatibility or stability. In many cases this can be alleviated by adding a USB hub inline between your computer and ECU/Driver Pack.
A USB hub can help particularly if your CMC is stopping or dropping in the middle of cuts or if the computer does not always recognize the ECU/Driver Pack. These can be found online or at your local computer store.
