I am developing KEXT using i/o kit for my usb bulk device and currently stuck while passing the data from "User application" to "Kernel application".

How do we get and set data from User space to Kernel Space and vice-versa ??


Read the documentation.

http://developer.apple.com/documentation/DeviceDrivers/Conceptual/ WritingDeviceDriver/index.html

Study especially the section "Making Hardware Accessible to Applications".
