I want to use communication with USB HID.

so, I tried "AN82072", almost work is fine.

but, send data to PSoC from PC is the problem to me.

I made c# application to test data transfer between PC and PSoC.

but sometimes the transfer is failed.

I also tried to find the problem with the Bus Hound program.

but I can not find any problem with the program, I think the data was sent to PSoC but PSoC does not receive the data.

so, PSoC does not send data to PC, 10 times.

I also tried with CY8CKIT-050 but has same problem.

This is My problem.

I attached my files, PSoC project and C# Application.

please refer the files and give me any advise to solve this problem.

Discussion moved to How to do USB HID communication with PSoC5LP?

Solution summary: Cypress HID Classes are no longer supported on Windows 10. CYUSB3.sys previously had support for HID Classes but now it is obsoleted. Please use the Windows HID libraries to develop your applications.

Hello,

Do you have actual USB Analyser hardware? If yes can you check if the device is NACKing for the IN tokens?

Did you check the C# application in different version of Windows? Are you facing same issue?

Thanks,

Hima

Dear Hima

Thank you for your advise.

Unfortunately, I do not have actual USB Analyzer hardware.

but I can try with different version of Windows.

I think "Windows 7" or "Windows Vista" is the different version of Windows, you mentioned.

am I right?

Thanks,

Yusang

Dear Hima

I tested the USB HID test with "Windows 7 Ultimate".

but I got the same result.

maybe Windows version is not the reason of the problem.

If you have any idea, please let me know.

Thank you again

Hello,

Can you add the following code snippet to the main loop and try again.

/* Place your application code here. */

        if(USBFS_IsConfigurationChanged() != 0)

            {

                if(USBFS_GetConfiguration() != 0)

                {

                USBFS_EnableOutEP(OUT_ENDPOINT);

                }

            }

Please refer to Troubleshooting PSoC® 3, PSoC 4 L-Series, and PSoC 5LP USB Designs – KBA210620

for more details on why this is required.

Thanks,

Hima

Dear HimaM_31

Thank you for your help.

but The Problem still exists even I added the cord.

And I found that the problem related with Windows version.
I am sorry about this situation before the experiment was wrong.

I prepared clean Windows 7(64bit) and Windows 10(64bit).

And I downloaded PSoC firmware with "AN82072" that Cypress supported.
I used C# application that contained in "AN82072" for my Test.

when I test with Windows 7, it is work perfectly.
but when I test with Windows 10, it is not working perfectly, To send the data to PSoC, I should click the button several times.

If you have any opinion to solve the problem, Please let me know.

Thank you again about your help.

I trying to make the environment as AN82072.

I am analysis the sample project that uploaded by Cypress for AN82072.

the sample project seems to be written by PSoC Creator 3.3 SP2.

so, I did compile and upload the firmware using PSoC Creator 3.3 SP2.

but Sample system is not working well.

In this time I am using CY8CKIT-050 to avoid change some code.

but To change PWM Duty Cycle, I have to push the "Update" button several times.

If you have any experience with this problem, Please let me know.
