make menuconfig 配置如下：
Device Drivers  --->
  SCSI device support  --->

(尽管在选择USB Mass Storage时会自动启用SCSI支持，也必需启用disk支持)
---   SCSI support type (disk, tape, CD-ROM)
<*>   SCSI disk support

(然后返回上一层，进入USB support)
USB support  --->

(这是根集线器，对于USB支持而言是必须的。如果你想把它编译成模块，那么它就叫做usbcore)
<*> Support for Host-side USB

(启用这一选项可以让你在/porc/bus/usb中查看USB设备，推荐启用)

   USB device filesystem

(至少要选择一个HCD。如果你不能确定，就都选上好了)
--- USB Host Controller Drivers
<*> EHCI HCD (USB 2.0) support
< > OHCI HCD support
<*> UHCI HCD (most Intel and VIA) support

(向下移动一下，就可以看到CDC和mass storage的配置选项了)
< > USB Modem (CDC ACM) support
<*> USB Printer support
<*> USB Mass Storage support

--- USB Input Devices
<*> USB Human Interface Device (full HID) support

   HID input layer support

(如果你有串口-USB转接器，譬如Prolific 2303，你需要开启这一选项)
USB Serial Converter support  --->
    <*> USB Serial Converter support
    <*> USB Prolific 2303 Single Port Serial Driver (NEW)
在网上查了很多资料，配置应该是这些了

应该UHCI模块注册上了，我应该在启动后，怎么看驱动是否加载呢？
