Help! I can't access the USB flash drive on the RDC6332NM controller
It's really frustrating. The controller equipped on my CO2 laser cutting machine is RDC6332NM. Everything else is fine, but after inserting a USB flash drive, it cannot be accessed. My USB flash drive is intact. I don't know what the reason is.

The target file should be placed in the root directory of the USB drive, but if there are too many root directory files, it may cause motherboard retrieval failure
