某老外2004.11.7发的帖子，关于DOS USB存储设备所用到的驱动及详尽解说。
老外同志研究得很透，分析得也非常全面，而且还提供了相关资源下载。值得推荐！
我看过了，评价极高。不过没空翻译。

Here are the known valid switches identified so far with the Panasonic(TM) v2.xx USBASPI.SYS driver in CONFIG.SYS
device=USBASPI.SYS ]
You can specify more than one controller type (e.g. /e /u). This switch can also be used to force slower speed operation on high-speed USB controllers & devices.
The driver will scan for all types of USB controllers, so use these switches to specify which port types to enable. This allows for faster USB scanning. By specifying /u or /o and omitting /e, it forces Full-Speed mode on High-Speed devices. Note that you can't make a Low- or Full-Speed device run at High-Speed.
/e EHCI, for enabling only USB 2.0 controller
/o OHCI, for enabling only add-on/onboard USB 1.1 controller
/u UHCI, for enabling integrated USB 1.1 controller
/w Wait, displays prompt message to allow swapping/attaching of target USB device
/l# Luns, to specify highest number of LUN assigned, default /L0
/slow to enter SLOW down mode, gives longer delays when scanning USB devices
/nocbc NO Card Bus Controller, to disable detection of USB on CardBus slots
/norst NO ReSeT, to prevent the driver from resetting USB peripherals which have been initialized by BIOS (USB legacy support) such as keyboards and mice.
