Question about Targus PAUH217U 4-Port USB Hub
I have a Targus 4 hub usb 2 port model no. PAUH217U. I am using it on an older laptop computer that has 1 usb port. On the Targus there is a pin that looks like it is for an external power supply. Is this for an external supply and if so what is the voltage. Should I use an external power supply on it?
Most USB hubs do not need an external power supply, except when a connected USB device draws more power than the computer/laptop USB port can supply. In this case an external power supply will need to be connected to the USB hub.
Normally this would be a 5 volt power supply, but make sure the polarity on the connector matches the power connector on the hub, check the label on the hub, sometimes it states to power requirements of the hub as well as the polarity on the connector. Normally the pin on the hub's power connector is positive (ie. +5V)

My Targus 4-port PA055U has printed below the power input 5V 2.6A. Finding the right AC adapter has been impossible.

My Targus hub has a split input/power lead. The power lead is red (ONLY supplies power) so both must be plugged in when using high power devices which sort of defeats the object of the bus if you have run out of spare ports as I have! I presume the power input socket of 5V and 2.6A max is a way around using the power USB lead. Note that the hub itself uses very little power, the 2.6A limit is the most that it can pass on to devices plugged into it. So plugging a Nokia charger of some 300mA will achieve nothing as the bus as it is can draw 100mA per socket to pass on.
My scanner draws 500mA and I presume the external HDD draws quite a lot too so I've had to plug these directly into the computer USB until I can find a power source for the hub.

Find any adapter that is a typical AC-DC adapter at 5V, the higher the Amperage the better (not above 2.6A of course). It is also amazing that this would need 2600mA! typical adapters provide a couple hundred mA... I found a 5V AC adapter providing 1.5A but the attachment is incorrect so I am severing the end and ataching one that fits. I'll update if it works!
