USB HID and USB MSC use together

[wanhuaqifang]

Hi, I'm trying to combine USB MSC class and USB HID compsite class together.

I based on the MSC example, added HID Code in it,But I founded that they cannot work together.

When I append both classes, the Windows prompt "DEVICE_DATA_SET_ERROR" and cannot recognize the MSC device. The HID class both work incorrectly.

But if I add one class at one time,it works very well.

So,does the SDK support USB MSC and USB HID work together?

Could you share your project, then I can take a look at it and try to resolve the conflict I encounter.

Best regards,

This is the example of USB MSC and USB HID,if you app_usbd_class_append one class of them,it works correctly.

But if you append them together it apperas "STATUS_DEVICE_DATA_ERROR"usb_and_msc.zip

A huge portion of the support team is currently on Christmas vacation and you may experience delayed answers. Most of the staff will be back 6 of January 2020 and you can be sure to get an answer shortly after that.

Haven't solved. I put HID Keyboard and MSC together,it works. But I put HID Keyboard and HID Mouse and MSC together,it won't works. But I need use HID Keyboard+HID Mouse+MSC together.

Have you checked if there are enough endpoints available?
