About Sonnet

Add More USB 2.0 Connections and a Bit of Power, Too. Portable drives, flash drives, iPod and iPhone mobile digital devices, memory card readers, mice, keyboards, printers, scanners, digital cameras, digital camcorders, audio interfaces, microphones, turntables - just how many USB peripherals do you own? How many USB ports does your computer have? Get Sonnet's 4-Port USB 2.0 ExpressCard/34 adapter so you can connect more of your USB peripherals at the same time.

Unlike a hub, this adapter has its own USB controller, so it doesn't share your computer's built-in USB bus-it provides more bandwidth to support maximum performance for the devices you connect. The Sonnet 4-Port USB 2.0 ExpressCard/34 adapter supplies 5V DC current to connected devices, so you can connect and operate your bus-powered 2.5" drive plus three low-power devices without plugging into an AC adapter!

This Sonnet adapter just works - it delivers plug-and-play operation, so there are no drivers to install and features hot-pluggable and hot-swappable device connection with automatic device configuration.

Sonnet Features

  • Simple way to add four USB 2.0 ports to any compatible computer
  • Supports bus-powered 2.5" drive plus three low-power devices - 5V, 650 mA capacity for all ports combined
  • Plug and play - no drivers to install
  • Supports simultaneous low-, full-, and hi-speed device connections. Maximizes performance for each port
  • Compatible in ExpressCard/34 and ExpressCard/54 slots

Lousy product and customer service.


from Boston, MA  -  High bandwidth user

Would have been nice if the product actually worked but no it was defective when it arrived. Adorama wouldn't refund me money, so overall the whole experience was a waste of time and money.
