General issue report

• usb_host_lib After reading the barcode gun, 57 hungry key_code appears directly, and it enters a dead loop

I'm using this example https://github.com/espressif/esp-idf/tree/master/examples/peripherals/usb/host/hid

Please tell me some ways or reasons,thanks

Through another project, usb_host_lib, the parameters of the scanning gun I am currently using are read as follows:

Closing the issue due to the duplicity. The same issue has been opened and is being solved in the espressif/esp-usb https://github.com/espressif/esp-usb/issues/26

Thank you for your reply. Yes, you are right. I submitted this question repeatedly because I was really troubled. I hope you can understand. Thanks again.
