1. How do I know if my PC has USB 2.0?
You can identify whether your PC has Hi-Speed USB or not relatively easy. Open Device Manager and expand the Universal Serial Bus section. There should be an "Enhanced" USB host controller present.
Windows 98 systems may use a different name, because Hi-Speed USB drivers in these operating systems are not provided directly from Microsoft (Windows ME, 2000 and XP get their drivers through Windows Update).

These drivers are provided by the manufacturer, and may carry the maker's name (i.e. ADS, Belkin, IOGear, Siig, etc.). There should also be two "standard" version USB host controllers present as well. They are embedded in the USB chip which routes the differing USB speeds accordingly without user intervention.

2. Do you need USB 2.0?
Almost every conceivable peripheral has USB 2.0 version ranging from a HDTV tuner, surround gaming headset, portable hard drive to even USB video card. So, even if you buy a all-in-one HP multimedia PC with all the gizmos, you'll still need something USB.

Should you own a laptop, you may like to know that USB is also your ticket out of the proprietary world. It used to be that docking stations must all match that exact notebook model due to the proprietary connection. Now, you can just plug in a USB notebook dock, and you'll get a USB video adapter, hub, 7.1 surround audio, serial converters, Ethernet plus a notebook holder.

3. How do I know I plug in a Hi-Speed USB device?
The simplest way is to look for a Certified Hi-Speed USB logo on the retail packaging or on the product itself. The logo is exactly as shown on the right; it tells you what you are plugging into your USB port has passed the Hi-Speed compliance tests, meaning the product can enter Hi-speed USB mode if your system supports it.
USB Info & SiSoftware Sandra can also report USB speed status. If you are certain you got some Hi-Speed USB ports, you can download the aforementioned utilities to check out your devices' USB speed (anything above 12Mbps is surely Hi-Speed USB).

4. How does USB 2.0 handle today's applications?
Many have asked us how USB 2.0 or Hi-Speed USB mode specifically can handle today's ever-changing applications, particularly in the multimedia field. The original USB has an inherent problem to meet the bandwidth requirement of then current CD burners and hard drives. If memory serves us well, USB CD burners hit the bottleneck at 8x or 1.2MByte/s, and USB hard drives couldn't exceed a pitifully 1MByte/s.

When USB 2.0 introduced Hi-Speed USB mode, it boosted bandwidth to 480Mbit/s or 60Mbyte/s. The forty-fold jump from the original USB's 12Mbit/s has paved way for a number of improved devices. As we've seen, there is a dual SDTV tuner, each of the tuners consumes 8Mbit/s after the MPEG-2 conversion. For DVB-T/B USB tuners, each HDTV stream requires 55Mbit/s or 11% of what USB 2.0 offers. Technically, Certified Wireless USB can handle several HDTV channels simultaneously. For a few USB Video Class-enabled camcorders available, DV mandates 3.6Mbyte/s (or 43Mbit/s) for the linear video stream; it fills up a hard drive at a rate of 13GB per hour.

As for a lot of USB storage, burning a DVD-R at its fastest rate or 16x takes up 21MByte/s or 169Mbit/s. That translates to 35% of overall USB 2.0 speed. Hard drives, however, demand huge amount of bandwidth that USB 2.0 cannot meet; we've seen a USB 2.0 hard drive has sustained 36 to 40MBbyte/s in the absolute best scenario. USB flash drives have also reached 33MBytes/s, but there seems to be some limitations in the NAND itself so you shouldn't expect their speeds to skyrocket in a next year or two. For most consumers, there shouldn't be a problem with running out of bandwidth.
