Unable to claim interface #152

Closed 2Steaks closed 5 years ago

2Steaks commented 5 years ago

Hi,

I have a Honeywell voyagar 1202g barcode scanner that I am trying to access on Windows. The device has been set up as a CDC ACM and I can use the device without issue on Mac.

I have been able to install the WinUSB driver using Zadig, I can connect to the device on Windows and I can even see the interface I need to claim. However, despite the interface saying it has not been claimed I still get the message "unable to claim interface".

Has anyone else experienced this?

So, after 2 days (was about to give up) and a complete fluke I got it working with Windows.

Steps to get it working:

  1. EZConfig (Honeywell software) to change Barcode scanner interface to CDC-ACM
  2. Install HSM USB Serial Driver Package
  3. Open device manager and update USB Composite Device driver (Let me pick from a list of drivers) to use Honeywell->WinFlash Intermec Device (without this step Zadig could not find it)
  4. Use Zadig software to update driver to libusbk
  5. Restart PC (important)
