This is a junk item. The PC does not recognize it properly. It is believed that the cause is a cracked solder joint on the IC chip of the control board. It was recognized normally when warmed with a hair dryer, but recently that doesn't work either, so I bought a new one. This is an item for those who have disassembly tools, those who are good at electronic work, or those who are looking for parts. No claims and no returns, please.
