The machine will not boot to the software updater screen when powering on and holding the U button. The USB deviced failed during a software update. Do not replace processor try to recover the software with the Software Update Recovery - NGC procedure.
[ERROR] appears during a software update or platform version update. The USB is not being read.
  1. Press [POWER OFF].
  2. Do the software update again with a different USB memory device.
Machines with 100.17.000.2040 of later, during a software update you get the following USB error: "The system check detected the USB connector is inserted into the wrong port on the skbif or main board......"
 The USB cable on the Maincon or SKIBF PCB is connected to the wrong location. Make sure the USB cable going to the SKIBF PCB is connected to the correct location, #2, on the Maincon PCB (See diagram below).
LCD Touchscreen
The TouchScreen does not respond to touch commands.		 The touchscreen USB cable is not connected correctly to the SKBIF PCB. Make sure that the USB cable connection is connected to J21 at SKBIF PCB.
The touchscreen continues to function after turning Setting 381 to OFF. The control does not recognize the touchscreen module.

Expected fix will be Software Version 100.23.000.1000.

Unplug the Touchscreen USB cable from the top port at J21 on the SKBIF PCB.

Note: When Software Version 100.23.000.1000 is released. Update the machine software, plug the touchscreen USB cable back into the SKBIF PCB at J21, and turn Setting 381 to OFF.

HSG-N 02-17-2023
Alarm 488 INTERMITTENT USB ERROR A communication timeout due to a faulty USB device.

Try a different USB device to see if the issue continues. Programs should be run from the control memory and not from the USB. Update the machine to the latest software.

If the alarms continues to generate, take an error report with the alarm present and submit it to Haas Service. Remove the USB device from the side of the pendant. If the alarm does not continue to generate, plug the USB directly into the SKBIF PCB or Main Processor PCB to find the faulty cable or PCB. If it does continue to generate, disconnect the other USB devices. See the Alarms 9100.017 & 9100.018 section below for steps.

Watch the video below and follow the troubleshooting done.

USB Error message and or USB alarms. There may be a grounding error. Cycle power and see if the issue persists. Refer to the following video: USB Read Error Troubleshooting
There may be a connection issue. Refer to the following video to check each connection: USB Read Error Troubleshooting
The control freezes. Faulty USB stick or USB hub on the Main Processor PCB or SKBIF PCB.

Try a different USB device to see if the issue continues. Programs should be run from the control memory and not from the USB.

If the control freezes and the machine is unresponsive, Cycle Power the machine and take an error report and submit it to Haas Service. If the issue does not continue. Install the USB to the bottom port of J21 on the SKBIF PCB. If no, replace the cable from the pendant to the SKBIF PCB.
Too much electrical noise in the system. Add ferrites to two SKBIF USB cables and add a new ground wire connected to the control cabinet. Refer to the SKBIF Reduce Electrical Noise section on the  SKIBF / LCD Monitor - Troubleshooting Guide for more information. 
The control has a laggy/delayed response. Faulty USB stick or USB hub on the Main Processor PCB or SKBIF PCB.

Try a different USB device to see if the issue continues. Programs should be run from the control memory and not from the USB.

If the control is laggy, remove the USB stick from the side of the pendant. If the issue continues, take an error report at the time of the issue and submit it to Haas Service. If it does not continue, install the USB to the bottom port of J21 on the SKBIF PCB. If the issue continues, take an error report at the time of the issue and submit it to Haas Service. If it doesnt continue replace the cable from the pendant to the SKBIF PCB.
