Splitting a USB Port

Using Arduino General Electronics
#1

Hey folks,
I am currently building a PC from an old Laptop, it will get its own fresh stylish case and inside that case I will need at least one Arduino, that is connected to a USB Port.

I would like to split one of the three outgoing USB Ports, while still inside, without losing the outside port. My guess is, if I just try to split it it will not work, a USB Hub probably has extra hardware.

Can anyone tell me if it is possible without adding extra hardware and if yes, how? Other wise I will probably buy an old USB Hub and get that inside.

Thank You

Yes. You need a hub.

You guessed correctly.

DVDdoug:
Yes. You need a hub.

Perhaps not surprisingly, that is exactly what hubs are for.

Why would you buy an "old" one? Should find one at the $2 shop. Should be USB 2.

If the laptop has a PCM-CIA slot (or its successor ExpressCard), you could use that to create an "internal" USB port by putting a USB card in it.
Might be a bit costly though.

Now I should also mention that unless you are only going to connect the hub ports to mice, keyboards and printers, you must use a "powered" hum with a 5V, 2A or better, power supply.

You cannot use an Arduino on a non-powered hub.

If the laptop have an Expresscard-slot, there is a USB-connection in the slot.
