From: Jiaming Ouyang <jiamingouyang13@gmail.com>
Translate Documentation/usb/ohci.rst into Chinese Simplified.
The translation covers OHCI driver overview, hardware protocol
differences (OHCI vs UHCI), improvements since 2.4 kernel,
queueable interrupt transfers, and non-PCI support.

+2002年8月23日
+
+“OHCI-HCD”驱动程序是一个USB主机控制器程序(HCD),它源自2.4内核系列中的“usb-ohci”
+驱动程序。“usb-ohci”代码主要由 Roman Weissgaerber <weissg@vienna.at>编写但也获
+得了来自David Brownell <dbrownell@users.sourceforge.net>,Linus Torvalds
+和Gregory P. Smith的支持。
+
+它支持“开放主机控制器接口”(OHCI),该接口标准化了用于与USB 1.1主机控制器通信的
+硬件寄存器协议。“与英特尔早期的“通用主机控制器接口”(UHCI)相比,它将更多只能功能
+注入到硬件中。除英特尔和威盛之外的其他供应商的USB1.1控制器通常使用OHCI。
+
+自2.4内核以来的更改包括
+
+ - 提高了健壮性; 修复了错误; 减少了开销
+ - 支持更新和简化的usbcore API
+ - 中断传输可以更大,并且可以排队
+ - 通过使用上层“hcd”框架,减少代码量
+ - 支持一些非PCI的OHCI实现
+ - ... 以及更多
+
+“OHCI-hcd”驱动程序处理所有USB 1.1传输类型。所有类型的传输都可以排队。在“usb-ohci”
+中也是如此,但中断传输除外。以前,使用一帧的周期会因为IRQ处理的开销而导致数据丢
+失的风险。当中断传输排队时,可以通过确保硬件在操作系统处理相关IRQ时始终有传输需要
+处理,来最大限度的降低这些风险。
