From the start the 4th computer could not be connected. One of the ports on the back just doesn't work and I'm using the cables that came with it. Also, when transferring data to a USB flash drive, other devices will stop working until the transfer is complete. This shouldn't happen since I'm also using the power cord. Sometimes there is a long delay when switching between computers. My computer makes a sound when I switch devices, but sometimes I have to switch multiple times for it to work. This behavior is not unique to a single computer or operating system. I have both an Apple and a PC. After all, something terrible happened today. The device loses power intermittently and I lose control of my peripherals. I've only had this hub for about a month and can't say it's a good product and worth the money. I have no desire. If he dies completely, give him a star.
