I am going out soon, and I found that important data on the computer was not copied to the USB flash drive. An embarrassing scene often appears at this moment: it will be late if you don't go out, but the copy progress is just 50%. Looking at the slowly increasing copy progress bar, is there any urge to crash you? If you can increase the USB transfer speed, you can definitely save energy waiting time and free up more time to deal with other things. The following system home teaches you how to increase the transfer speed of USB devices. Gradually become the mainstream USB3.0 If you want to buy a new PC (notebook), be sure to select a more number of USB3.0 interface products, and choose a USB3.0 interface mobile hard disk or U disk with it, enjoy the highest speed data Transfer service. It should be noted that the PC platform wants to experience the speed of USB3.0. It also needs USB3.0 driver and USB3.0 data cable support. If you buy a new computer, you don't have the relevant driver installed, or you can use the eliminated USB2.0. With the data cable, USB 3.0 becomes a display, which leads to an increase in data transmission time. The potential of mining USB2.0 interface has come. Many old PCs are not equipped with USB3.0 interface. How can we save the time of data transmission? For notebook users, if your machine is equipped with a PC card slot, you can get the USB3.0 interface through the PC card slot to the USB3.0 expansion card. If you are a desktop or a notebook without a PC Card slot, you can manually add the USB peripheral INF by installing the Microsoft Windows 6.1-KB2581464 patch (download address: http://pan.baidu.com/s/1pJ19Rej). The way of information increases the maximum transfer speed of the USB 2.0 interface. After installing the patch, we also need to write the INF information of the USB storage device such as the U disk and the mobile hard disk to the registry. Take a USB flash drive as an example, connect it to the PC and go to “Device Manager & Rarr; Disk Drive”, double-click the USB flash drive and enter its properties window “Details” tab interface, in the drop-down menu. Select “Family”, in the "value" dialog"VID_xxxx&PID_xxxx” string xxxxxxxx is the unique INF information corresponding to the U disk. For example, the parent value of the author's U disk is “VID_090C&PID_1000”, and the corresponding INF information is “090C1000” (Fig. 1). Next, enter the registry editor, create a new item named "ldquo;090C1000" in HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\usbstor”, and then create a new DWORD value named "MaximumTransferLength" in the item, and It gives the decimal value of “2097120” (Figure 2). After saving, restart the PC. At this time, you can connect the USB flash drive to the PC, and you will find that the U disk transfer file speed is obviously faster (Figure 3-4). Tips The KB2581464 patch only supports Windows 7 systems. Windows 8 or higher systems have integrated this patch. To increase the speed of the USB 2.0 interface, you only need to add the INF information of the USB peripheral directly. Further reading: use the network to copy data between PCs to use USB storage devices as "mediation", and then transfer data between multiple devices, even if the reading speed of USB devices is higher, it is a more formal procedure. Not the most efficient option. If the PC or mobile phone that needs to transmit data happens to be together, you can use the network cable (PC→ PC) or wireless to bypass the USB flash drive for one-to-one data transmission.
