This is a junk item: a BUFFALO 4-port self-powered hub, model BSH4A11. The AC adapter is included, but I'm not sure which USB A to micro B cable originally came with it, as I've lost track. While it does work, the cable is either damaged or has poor contact, causing the connection to be interrupted by impacts during use. Therefore, I'm selling it as a junk item. Please understand. It will be shipped via Takkyubin Compact.
