0:00:57.240 --> 0:01:04.560
<v Speaker 1>com slash brain Stuff. Hi. I'm Marshall brain with today's question,

0:01:05.000 --> 0:01:07.720
<v Speaker 1>how do you add a USB device to your computer

0:01:08.000 --> 0:01:11.880
<v Speaker 1>if you've run out of USB ports? A typical desktop

0:01:11.920 --> 0:01:15.880
<v Speaker 1>machine comes with four USB ports, and laptops can come

0:01:15.920 --> 0:01:18.840
<v Speaker 1>with as few as too, so it's easy to use

0:01:18.880 --> 0:01:22.080
<v Speaker 1>them up. Because there are so many USB devices out

0:01:22.080 --> 0:01:28.120
<v Speaker 1>there mice, keyboards, scanners, printers, thumb drives, external drives, microphone, webcams,

0:01:28.120 --> 0:01:31.200
<v Speaker 1>and so on, they all need a port, and with

0:01:31.360 --> 0:01:34.080
<v Speaker 1>so many USB devices on the market today, you can

0:01:34.160 --> 0:01:37.640
<v Speaker 1>run out of sockets very quickly. The easy solution to

0:01:37.680 --> 0:01:41.679
<v Speaker 1>the problem is to buy an inexpensive USB hub. The

0:01:41.800 --> 0:01:45.760
<v Speaker 1>USB standard supports up to a hundred and twenty seven devices,

0:01:45.800 --> 0:01:49.480
<v Speaker 1>and hubs are a part of that standard. Hub typically

0:01:49.560 --> 0:01:52.960
<v Speaker 1>has four new ports, but could have many more. You

0:01:53.040 --> 0:01:55.880
<v Speaker 1>plug the hub into your computer and then plug your

0:01:55.920 --> 0:02:00.640
<v Speaker 1>devices or other hubs into the hub. By chaining ubs together,

0:02:00.720 --> 0:02:03.760
<v Speaker 1>you can build up dozens of available USB ports on

0:02:03.800 --> 0:02:08.760
<v Speaker 1>a single computer. Hubs can be powered or unpowered. If

0:02:08.800 --> 0:02:12.880
<v Speaker 1>you have lots of self powered devices like printers and scanners,

0:02:13.200 --> 0:02:16.040
<v Speaker 1>then your hub does not need to be powered. None

0:02:16.040 --> 0:02:19.000
<v Speaker 1>of the devices connected to the hub need additional power,

0:02:19.320 --> 0:02:22.200
<v Speaker 1>so the computer can handle it. If you have lots

0:02:22.240 --> 0:02:26.840
<v Speaker 1>of unpowered devices like mice and cameras, you probably need

0:02:26.880 --> 0:02:30.400
<v Speaker 1>a powered hub. The hub has its own transformer and

0:02:30.480 --> 0:02:33.079
<v Speaker 1>it supplies power to the devices that connect to the

0:02:33.160 --> 0:02:36.960
<v Speaker 1>hub so the devices don't overload the computer's power supply

0:02:37.680 --> 0:02:41.000
<v Speaker 1>from maximum speed. Make sure that the hub you buy

0:02:41.120 --> 0:02:44.920
<v Speaker 1>handles USB two point oh one advantage of buying a

0:02:45.000 --> 0:02:47.600
<v Speaker 1>hub if you buy one that looks good on your desk,

0:02:48.120 --> 0:02:51.799
<v Speaker 1>is that it makes USB access a lot easier. When

0:02:51.840 --> 0:02:53.960
<v Speaker 1>you need to plug in a thumb drive, you can

0:02:54.000 --> 0:02:57.160
<v Speaker 1>do it at desk level rather than down at floor level.
