I am trying to find out why the devices are not showing under /dev/bus/usb. I dont even find the folder bus inside /dev. Can you please let me know if there are any configuration that is needed? Also, i dont see udev daemon running on the box. regards, Ahamed On Wed, Feb 10, 2016 at 1:21 AM, Greg KH <greg@xxxxxxxxx> wrote: > On Wed, Feb 10, 2016 at 01:04:57AM +0530, Ahamed wrote: >> I hope you are well and doing great. >> >> I really want some help from you regarding the /dev/bus/usb >> >> >> Initially, we were on 3.4 Kernel and were using usbfs.
