Hi
I am trying to connect a raw hid device to my esp32s3 board but am battling to find enough information. When running the usb_host_lib example the device gets picked up :

but I cannot find a way to send raw hex strings to it. In linux it shows up as a /dev/hidrawX instead of ttyUSB or ACM. I suspect that is why I am seeing errors like this from the framework
<code>
[0;31mE (767) HUB: Stage failed: CHECK_SHORT_MANU_STR_DESC[0m
</code>
Has anybody got any suggestions or perhaps come accross a sample that does something like this?
