Features Peripheral Sharing: Allows you to share a USB peripheral between four separate computers and eliminates the need for peripherals attached to each computer, which saves money, space and time when setting up a multi-PC application. Space-Saving: Space-saving functionality is perfect for home or office workstations that need to share a printer, scanner or high-capacity hard drive among multiple PCs. USB Compatibility: Compatible with both USB 2.0 and USB 1.1 so it can be used with any USB peripheral that needs to be shared. Operating Systems: Compatible with Mac OS X up to 10.11 and Windows 98SE/2000/ME/XP/Vista/WIN7/8/8.1/10 (both 32 and 64-bit versions). High-Speed Data Transfer: Supports high-speed USB 2.0 peripherals with transfer rates up to 480 Mbps. Plug-and-Play Convenience: Self-powered and easy to setup with the included software disk. Switching from one to another computer is effortless with one-touch port switching via a mouse, hot-key or manually. Display LEDs: Active indicator LEDs alert the user to which computer currently controls the switch. No External Power Needed: Since power is drawn through the USB cables, no separate AC adapter required.
