To add on the version for driver and USB device.

STM32L0xx HAL Driver: V1.1.0

STM32 USB Device Library: V2.2.0

Kindly help if you know what could be wrong on the data receiving part.

Thanks a lot.

Hi Chang,

Are you looking for STM32 example or PC application example?

For PC side i can recommend HIDSharp which worked quite well with my STM32L1 custom HID firmware. It sends output reports, not feature reports.

If you have troubles with STM32 HID reception then i guess you need to bring in the debugger and start looking where is the problem. First check that the endpoint OUT callbacks are called (EP1_OUT_Callback) when you send something from PC.

Hi Leini,

I was looking for the STM32 example for custom HID. I found the similar example from STM32F3 library.

I was having problem to receive the data from PC, sometime the received data is correct, sometime it is wrong. There seems to be some memory allocation issue in the USB device library as pointed by another discussion.

Anyway, thanks for your advise.

Thanks a lot.

Best regards,

Chang
