Can you refer to the msdn article in the following link where the error "ERROR_ACCESS_DENIED" is explained.
Can you check that and let us know if the error persists. If it still exists can you share the project?
Thank you for your reply!
Finally I find it's device accessor problem, now I can open device in UWP program by edit registry as below article:
Now the problem is I want to port our device to Win10 IOT platform, but we only have x86/x64 driver in Cypress\EZ-USB FX3 SDK\1.3\driver\bin, can you provide driver for ARM platform's Windows?
Thanks in advance!
Got it! Thank you very much!
