USBScope50

This repository contains software for the USBScope50 digital oscilloscope.

Description as well as some very useful hints can be found in the old archived page and comments. Future discussions should happen here.

Initial Setup for Windows

After extracting USBscope50-Java-Software-with-JRE.zip, place the folder in the following directory.

C:\Program Files\Elan Digital Systems\USBscope50 Java Software

After connecting USBscope50, start Java from start.bat.

VCP Driver Installation for Windows

The standard Virtual COM Port (VCP) driver does not support the VID/PID used by USBscope50. Therefore, a custom VCP driver must be created using Silicon Labs' custom driver creation software. If the custom VCP driver is self-signed, it will work properly on Windows with Secure Boot enabled.

Note

Custom VCP drivers are based on signed drivers provided by Silicon Labs. Although the security issue is considered low, please select the target files carefully and proceed at your own risk when self-signing.

1. Required Software and Files

   • The test certificate registered in the Trusted Root Certification Authorities Certificate Store on the local PC
     • Please refer to Microsoft's "How to Test-Sign a Driver Package" to create a test certificate file (.cer).
       • Visual studio
       • Windows SDK
       • Windows Driver Kit
       • These installations are required.
   • CP210x Software package for Windows, includes VCP drivers
     • Please download and install from Silicon Labs.

2. Creating a Driver with CP210x Driver Customization Utility (AN220)

   1. Select the Driver to Create

      Check the driver type and the driver file output method. You can select "Executable Installer".

      • Virtual COM Port Driver Installation
      • INF Files only

      

   2. Editing the Device List

      Delete everything in the Device List and add USBscope50.

      • Device Type: CP2101/2/3/4
      • VID = 10C4
      • PID = F001
      • Device Name: USBscope50

      

      

   3. Check the Driver Configuration

      Install Type:           VCP Driver Set
      Company Name:           Silicon Labs
      Abbreviation:           10C4/F001
      VID/PID:                slabvcp.inf
      INF File Names:         CP210x USB to UART Bridge
      COM Device Name:        No
      Serial Enumeration?     No
      Selective Suspend?      No
      S. Suspend Timeout:     -
      Generate Installer?     No (or Yes)
      Product Name:           -
      Installer Name:         -
      Display Install?        -
      Copy Files?             -
      Relative Install Type:  -
      Target Directory:       -
      Display Uninstall?      -
      Remove Files?           -
      

      If Serial Enumeration and/or S. Suspend Timeout are enabled, go back a few pages and uncheck the Serial Enumeration Support and Selective Suspend Support checkboxes.

      If successful, an .inf file will be generated in the specified folder.

      

      

3. Generating Binary Drivers with inf2cat

   Use inf2cat to convert the .inf file to .cat. Note that you need to specify the folder where the .inf file is located, not the path to the .inf file.

   developer powershell for vs 2022 Code Sample

   inf2cat /drv:'your\driver\directory' /os:10_NI_X64
   

4. Signing Binary Drivers

   Embed your test certificate in the .cat file. (Reference)

   developer powershell for vs 2022 Code Sample

   Embed

   Signtool sign /v /fd sha256 /s PrivateCertStore /n 'YourSignatureName' 'your\driver\binary.cat'
   

   Verification

   Signtool verify /pa /v 'your\driver\binary.cat'
   

5. Installing the Driver

   Right-click on the generated .inf file and install it.

6. VCP Driver Operation Check

   Connect USBscope50 to your PC and check that it is recognized in the Device Manager. If you are using a stack configuration, please also check that all USBscope50 devices are registered with different COM ports.

   Device Manager -> Ports (COM & LPT) -> USBscope50(COM...)
