Firmware - NeXTUSB

There are two microcontrollers on the NeXTUSB, there's one file for each of them.

  • Place one file (not both) on a FAT-formatted USB flash drive and plug it into the NeXTUSB while it's running. Make sure the file name stays the same.

  • The red LED in the device will flash 4 times and then wait 5 seconds to begin.

  • If updating NEXTUSB.ROM, the red LED will flash very rapidly while updating. Once it stops, remove the flash drive. Press the reset button on the device.

  • If updating NEXTUSB8.ROM, the red LED should flash 4 times rapidly when it succeeds. It may take two or three times to finish, so let it repeat the process (flash slowly, wait 5 seconds, wait for rapid flashes) until it succeeds. There's no need to reset the device after updating this controller.
