Kindly help me. Ah, I'm amazed that that driver even builds (well, I guess it doesn't.) Please contact the author of that driver to fix that problem, I can't build it (don't have the proper cross-compiler tools), and can't test it, so you would be the best one to be able to resolve these types of bugs. > >> I Right now i am not able to get any uevents or Udev events in my > >> driver when i plug or unplug the USB. > > > > Driver's don't get uevents. > > The kindly let me know what gets the uevents. should i add some code in my driver file to get uevents from Apps > >> Kindly guide me to get the uevents or introduce UDEV in my driver file > >> so that i get the events every time i plug or unplug the device. > >> > >> Once i get the uevents i need pass the uevents to application/UI and > >> pass the control to switch from block driver to usb mass storage > >> driver > > > > What is wrong with the existing framework that Android provides for this > > type of thing?
