The controller does not have enough bandwidth to take advantage of the solution for USB mass storage devices

Along with the decline of the era of the network, recently started a mobile hard disk. Now the mobile hard disk is USB3.0, the transmission speed is much faster than the USB2.0. But after the link notebook computer found the transmission speed around 20mb/s, with USB2.0 speed is similar, and can not reach the legendary 70-80mb/s. And just when you plug in the computer, it pops up. "The controller does not have enough bandwidth to take advantage of the USB mass storage device."

In fact, this can be seen, the hardware is to support USB3.0, then the problem is certainly in the software, so it is natural to think of the driver's problem, the online Baidu USB3.0 Universal Drive seemingly no effect, and then use the notebook official website of the USB3.0 drive OK. Inserting a mobile hard drive no longer reports the above error. At the same time the transmission speed increased to about 50-60mb/s. Obviously, it's more effective than the previous 20mb/s. But the wood has reached 70-80mb/s. Thinking in:

So, by the way, how to use USB3.0. Reach the party can jump to the end to see the summary ~

1, first of all your mobile hard drive to support USB3.0. The words. Just look at the parameters of the hard drive below and you'll know.

2, a support USB3.0 data cable. Now the new mobile hard drive standard will be included with one, the distinction method can be referred to in the 3rd Step (2).
