The reason is ITead missed they need to write “description” to EEPROM on USB-to-UART chip, see:
Great if more people report this issue to ITead as they need to make and release a script that writes a “description” to the CP2102N EEPROM so will no longer discovered using Silabs default description.
Hopefully, they will at least fix this in the next batch (or the next batch after that) so discovery will work.
