hi all: I have read the article below and try to do the same operation on my device. http://lwn.net/Articles/143397/ My environment: 1. my kernel is 3.16 2. device descriptor is attached. 3. below are my operation logs: # echo -n "4-2:1.0" > /sys/bus/usb/drivers/uas/unbind # echo -n "4-2:1.0" > /sys/bus/usb/drivers/usb-storage/unbind bash: echo: write error: No such device # My questions: 1. is there anything I need to do, such as PCI driver, before bind to usb-storage driver? 2. I can check whether the usb device is bound to specific driver through "cat /sys/kernel/debug/usb/devices". is there any alternative way to do so? how about other drivers, except usb, to let user know whether the binding/unbinding successfully and which device is bound to which driver? thanks for your help in advance,
