I have bought scanners for the register, but wonder if the USB scanners may last longer.** A: This is a serial to USB converter, not vice-versa. If your scanner has a USB connection already, then this item is of no use to you. By the way, less and less laptops (and I would assume desktops) come equipped with a COM port (that is why I needed this converter), so opting your USB port for a COM port sounds more of an own goal. Perhaps I misunderstood your question. **Q: is it prolific** A: Prolific chips often exhibits erratic behavior with some serial devices. The reliable chip is the FTDI chip. **Q: Will this work to connect a computer to a CISCO Switch via the console cable?** A: Yesssss its a great usb to serial cable **Q: I assume this will plug and play with WIN10 64x ...? thanks!** A: It is just a cable so I would assume so. My husband uses it with his Windows 10 laptop to connect to his telescope. ## Frequently Bought Together - TRENDnet USB to Serial 9-Pin Converter Cable, TU-S9, USB to RS232 Serial Adapter, Supports Windows & Mac, USB 1.1, USB 2.0, USB 3.0, 64cm (25 in.)
