Why doesn't Windows provide Host API to get all the descriptors directly?
« 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:
