Road Warrior's Hub
Keyspan packs four USB ports into your pocket.
If you're like me, you've been accumulating USB peripherals lately, because
they're just so convenient. And if you're a road warrior, you've probably
reached the point of being annoyed at the limited supply of USB ports
on your laptop. Needing to unplug your mouse to plug in an external CD
burner is a real nuisance.
Keyspan has produced a new USB hub targeted squarely at the mobile market.
It's about the size of a credit card and a centimeter thick -- comparable
to a PCMCIA Type III card in size. The cable that you plug into your computer's
USB port hides inside the hub when not in use, making it easy to tuck
away anywhere. When in use, you get four USB 1.1 ports.
The device's major compromise is in the use of an external power adapter
that's about half the size of a deck of cards. The Keystone engineers
did their best to work around this nuisance by allowing the hub to work
in either bus-powered mode or adapter mode. When in bus-powered mode it
supplies 100 ma to each connected device; when in adapter mode, it supplies
the full 500 ma called for by the USB spec. This won't be an issue for
many devices; I had no trouble with my USB trackball or digital camera
transfers when in bus-powered mode.
The Keyspan hub works with Windows 98/ME/2000/XP, as well as Mac OS 8.0
or greater and Linux 2.4.1 and up kernels.
