Most of the current USB products (USB flash drives, removable hard drives, digital cameras, scanners, etc.) already support USB 2.0. As long as the driver is installed correctly, you can enjoy the pleasure and joy brought by super-fast data transmission!
USB 2.0 can also be used under DOS:
The USB 2.0 interface has become the standard interface of current motherboards. Due to its transmission speed 40 times higher than the USB 1.1 interface, it is popular. But under DOS, due to driver issues, we cannot enjoy the high speed brought by USB 2.0. Now, I will tell you a method to let you enjoy the high speed of the USB 2.0 interface under DOS.
First, determine the version of the USB driver under DOS provided by your computer. Open "Device Manager", expand "Universal Serial Bus Controllers". If there is "Enhanced Host Controller Interface", it is a high-speed USB, that is, EHCI supported by the USB 2.0 controller. Next, download a driver program named "Cypress DUSE" from the Internet. Make a Windows 98 boot floppy disk. Copy the "DUSE.exe" file to the boot floppy disk, then edit the "config.sys" file and add the line "DEVICE=DUSE.EXE INT13 DRIVES=2", save and exit.
Finally, use the boot floppy disk to boot the computer, and you can use the USB 2.0 interface device under DOS.
