Gratitude for 'Alan Stern' spend time for me. I found the 'onetouch' driver there, and found the record in 'unusual_devs.h', It seem not defined by usb framework. I searched the UNUSUAL_DEV keyword on google. It seems used for add vendor/product number for unsupported mass storage device. I still didn't understand the way of onetouch driver work. Should I create a speicial file for map to the function? Can you give me document link for start? Thanks for your help.
