Broadcom的主版kernel run起来的时候，讯息有秀出：
...

usbcore: registered new driver hub

由kernel的讯息是 USB core, UHCI controller, OHCI controller 和 USB storage 的driver都挂起来了，但是我插了USB flash 随身碟上去，在 /dev/下没有看到 sd* 档案的挂载，在
/proc/bus/下也只有PCI没有USB的资料夹，没办法检视/proc/bus/usb/devices这个档案...
请问一下各位先进，
还有哪些地方可以用来检视，或是验证现在USB问题发生在何处？？
哪里还有资讯可以验证现在的USB core 或是 USB controller (OHCI,EHCI)是否work正常？
