[dba-Tech] Getting used to Windows 8

Be careful when using the octopus. You should know that every USB device
connected draws some current from the USB port. The standard USB port only
provides a max. of 500 mA. If the devices connected to the octopus add up to
a consumption of more than 500 mA provided the provided 5V will drop and
nothing works anymore.
The way to solve this problem is to get an active USB hub with an own power
supply. They will provide up to 4 Amp. current which should be adequate for
most usages.

There is a port on the left side which I initially assumed was a USB port,
but isn't.  It looks a lot like a standard USB port, though. Maybe it's the
ExpressCard port?

I think I'll also have to get one of those "octopuses" that has one USB
port on one end that branches into 5 or so USB ports on the other end. I've
already used all my USB ports and i have three devices that are not hooked
up. It's a hassle having to swap them in and out. I guess one should never
complain about having too many devices :)
