CySuiteUSB contains an example CYUSB.INF file. The latest inf adds some registry entries which didn't appear in early versions and aren't in my customized inf:
What do these entries actually do? Is it important to add them to my inf and re-release or does the driver work without these entries?
Please look at section 188.8.131.52 of www.cypress.com/?docID=22323
You can use it to store parameters and retreive and modify host app behavior etc.
It is not mandatory.
