If eKnitterFlash cannot see eKnitter

If the flash tool cannot find eKnitter, the most common reasons are a missing USB driver, the wrong cable, a charging-only cable, or a USB connection that was not detected correctly.

  • Use the correct USB data cable: Micro USB for KH 910, USB-C for KH 930 / KH 940.
  • Make sure you are not using a charging-only cable.
