In my USB driver, I use "usb_register" and "usb_register_dev"
to register usb_driver and usb_class_driver to usb core. I
also create some attribute files for my driver
When the device plugging in, its init and probe functions had
no error and work well
I found the attribute files under /sys/bus/usb/devices/1-1:1.0
, the name of usb_driver under /sys/bus/usb/drivers, the name
of usb_class_driver under /sys/class/usb. But I can't see the
anything under /dev
I tried to open the name of full-path of of usb_class_driver to
send ioctl commands, but it shows message:"can't open"
How to open device node for sending ioctl commands? After
using "usb_register" and "usb_register_dev", where do
system create device node?
Please give me some information
ps: I use kernel version is 3.0.8 and platform is Galaxy Nexus
