12、在低电力模式，USB 3.0提供了150mA的电流，这比USB 2.0还增加了100mA。

13、USB 2.0 devices rarely ever reached much more than 50% of the maximumtransfer rate, and it's unlikely that USB 3.0 will either.

14、The Research of the DMB-TH Digital TV Receiving System Including the Software Based on USB 2.0;

15、论文将US b接口与其它计算机接口进行了比较，总结出usb接口的优点，并深入地研究了USB 2.0协议。

16、The performance specs of Thunderbolt are striking: At 10 Gbps, it’s twice as fast as USB 3.0, 12 times as fast as FireWire 800 and 20 times faster than USB 2.0.

17、It moves data, and in the case of USB 2.0-which is pretty much the standard now-it does it faster, and with some extra specs for power.

19、System requirements call for Mac OS X 10.5.6 or later, Intel Core processor, 512MB RAM, built-in USB 2.0 port and QuickTime 7.6 or later.

20、Meanwhile, on the other side there's a covered full-sized SIM card slot and a dev port, and another USB 2.0 port.

21、从速度来看，在USB 2.0和FireWire之间没什么可选择的：虽然usb 2.0报出的速度较高，实际上因为协议不同，它们都是差不多的。

22、With the exception of a memory card slot and covered 3.5mm headphone jack and USB 2.0 ports, you won't find any openings on the sides or front lip of the laptop.

23、随着消费外设阳光照出地平线的热潮，我们决定帮助大家整理一下关于USB 2.0成功的混淆。

24、以目前最为标准的USB 2.0为例，它移动数据的速度更快，而且还有一些额外的电源规格。

25、机身的右侧则具备一个标准尺寸的SIM卡*槽，和它一起藏在弧形盖子内的则是另一个工程开发用的端口。 同一侧还具备另一个USB 2.0端口。

26、US B驱动器浪费较少的时间来访问数据，并且还提供了更高的数据率在很多情况下，即使当驱动器的USB 2.0规范。
