16
00:00:57,240 --> 00:01:04,560
Speaker 1: com slash brain Stuff. Hi. I'm Marshall brain with today's question,

17
00:01:05,000 --> 00:01:07,720
Speaker 1: how do you add a USB device to your computer

18
00:01:08,000 --> 00:01:11,880
Speaker 1: if you've run out of USB ports? A typical desktop

19
00:01:11,920 --> 00:01:15,880
Speaker 1: machine comes with four USB ports, and laptops can come

20
00:01:15,920 --> 00:01:18,840
Speaker 1: with as few as too, so it's easy to use

21
00:01:18,880 --> 00:01:22,080
Speaker 1: them up. Because there are so many USB devices out

22
00:01:22,080 --> 00:01:28,120
Speaker 1: there mice, keyboards, scanners, printers, thumb drives, external drives, microphone, webcams,

23
00:01:28,120 --> 00:01:31,200
Speaker 1: and so on, they all need a port, and with

24
00:01:31,360 --> 00:01:34,080
Speaker 1: so many USB devices on the market today, you can

25
00:01:34,160 --> 00:01:37,640
Speaker 1: run out of sockets very quickly. The easy solution to

26
00:01:37,680 --> 00:01:41,679
Speaker 1: the problem is to buy an inexpensive USB hub. The

27
00:01:41,800 --> 00:01:45,760
Speaker 1: USB standard supports up to a hundred and twenty seven devices,

28
00:01:45,800 --> 00:01:49,480
Speaker 1: and hubs are a part of that standard. Hub typically

29
00:01:49,560 --> 00:01:52,960
Speaker 1: has four new ports, but could have many more. You

30
00:01:53,040 --> 00:01:55,880
Speaker 1: plug the hub into your computer and then plug your

31
00:01:55,920 --> 00:02:00,640
Speaker 1: devices or other hubs into the hub. By chaining ubs together,

32
00:02:00,720 --> 00:02:03,760
Speaker 1: you can build up dozens of available USB ports on

33
00:02:03,800 --> 00:02:08,760
Speaker 1: a single computer. Hubs can be powered or unpowered. If

34
00:02:08,800 --> 00:02:12,880
Speaker 1: you have lots of self powered devices like printers and scanners,

35
00:02:13,200 --> 00:02:16,040
Speaker 1: then your hub does not need to be powered. None

36
00:02:16,040 --> 00:02:19,000
Speaker 1: of the devices connected to the hub need additional power,

37
00:02:19,320 --> 00:02:22,200
Speaker 1: so the computer can handle it. If you have lots

38
00:02:22,240 --> 00:02:26,840
Speaker 1: of unpowered devices like mice and cameras, you probably need

39
00:02:26,880 --> 00:02:30,400
Speaker 1: a powered hub. The hub has its own transformer and

40
00:02:30,480 --> 00:02:33,079
Speaker 1: it supplies power to the devices that connect to the

41
00:02:33,160 --> 00:02:36,960
Speaker 1: hub so the devices don't overload the computer's power supply

42
00:02:37,680 --> 00:02:41,000
Speaker 1: from maximum speed. Make sure that the hub you buy

43
00:02:41,120 --> 00:02:44,920
Speaker 1: handles USB two point oh one advantage of buying a

44
00:02:45,000 --> 00:02:47,600
Speaker 1: hub if you buy one that looks good on your desk,

45
00:02:48,120 --> 00:02:51,799
Speaker 1: is that it makes USB access a lot easier. When

46
00:02:51,840 --> 00:02:53,960
Speaker 1: you need to plug in a thumb drive, you can

47
00:02:54,000 --> 00:02:57,160
Speaker 1: do it at desk level rather than down at floor level.
