Universal Serial Bus (USB) is a Plug'n'Play interface intended to allow connection of a variety of devices to a PC. USB can offer an excellent alternative to internal ISA and PCI cards for adding serial ports to your system. The USB specification allows up to 127 devices to be connected to a single host. If you need multiple devices, or would like to isolate your application from the host PC, check out B&B's USB Hubs

B&B offers a number of USB solutions for making connections to serial devices of all kinds.
