Does it recognize other peripherals plugged in? If the usb port is good you have need of drivers for your Zip drive. Or the bad news is, the zip is bad.

IOMEGA make a USB ZIP drive that reads and writes 100 and 250 Mb disks. Don't know if this is available any more, you might be able to pick one up 2nd hand.
If you still have your old computer, try networking your old and new computer together so you can transfer data from the ZIP drive on your old computer to your new one.
