Title: Why doesn't Windows provide Host API to get all the descriptors directly?
Post by: yindengxie on August 15, 2020, 10:07:20 am

Hello Jan,

Why doesn't Windows provide Host API to get all the descriptors directly,
but need to get these descriptors through USBView or some paid software?

    THANKS!

TDD is free:

These programs get the descriptor by calling the Windows setup API.

Source code to USBView is here:
