那我把驱动程序的使用方法也总结一下吧，例如：
DEVICE=OHCI.EXE (USB-OHCI鼠标)
DEVICE=UHCI.EXE (USB-UHCI鼠标)
DEVICE=DUSE.EXE DRIVES=2 (USB驱动器)
DEVICE=RAMFD.SYS ( ...
USB Hoster Controller: OHCI vs.UHCI
-OHCI=Open Host Controller Interface.是一种标准的USB主控制器接口，由Compaq,Microsoft
及National Semiconductor Corp.提出，目前已被25个上的公司支持。.大多数便携式计算机使用
OHCI标准芯片，台式PC目前的熟练也成增长趋势。
-UHCI=Universal Host Controller Interface.是一种标准的USB主控制器接口，该版本由Intel.
公司开发。大多数台式PC使用这种接口标准，便携式PC很少使用。
USB总线提供两种信道速度：1.5Mbps和12Mbps。低速设备主要有：键盘，鼠标，游戏棒等；高速设
备主要有：打印机，扫描仪,Modem,USB hub,CDW等。OHCI标准的USB控制器当前存在的问题是：不
能很好地控制两种速度的转换。
固当外设使用USB口同主机连接使用发生问题时，应留意两种接口标准的特点。

Let me also summarize the usage of the driver program, for example:
DEVICE=OHCI.EXE (USB-OHCI mouse)
DEVICE=UHCI.EXE (USB-UHCI mouse)
DEVICE=DUSE.EXE DRIVES=2 (USB drive)
DEVICE=RAMFD.SYS ( ...
USB Hoster Controller: OHCI vs. UHCI
-OHCI = Open Host Controller Interface. It is a standard USB host controller interface proposed by Compaq, Microsoft, and National Semiconductor Corp., and is currently supported by more than 25 companies. Most portable computers use OHCI standard chips, and the popularity among desktop PCs is also growing.
-UHCI = Universal Host Controller Interface. It is a standard USB host controller interface developed by Intel Corporation. Most desktop PCs use this interface standard, and portable PCs rarely use it.
The USB bus provides two channel speeds: 1.5Mbps and 12Mbps. Low-speed devices mainly include: keyboards, mice, gamepads, etc.; high-speed devices mainly include: printers, scanners, modems, USB hubs, CDWs, etc. The current problem with OHCI standard USB controllers is that they cannot well control the conversion between the two speeds.
Therefore, when there are problems when the peripheral device is connected to the host using the USB port, the characteristics of the two interface standards should be noted.
