will this connector work for my royal cash register? I have bought scanners for the register, but wonder if the USB scanners may last longer.

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.

Prolific chips often exhibits erratic behavior with some serial devices. The reliable chip is the FTDI chip.

Will this work to connect a computer to a CISCO Switch via the console cable?

Yesssss its a great usb to serial cable

I assume this will plug and play with WIN10 64x ...? thanks!

It is just a cable so I would assume so. My husband uses it with his Windows 10 laptop to connect to his telescope.
