Vadim, If you want to access to Userspace and load a binary files from KS, use request_firmware() . But as Greg said, you have to better understand the meaning of kernel space.

Some customers want their devices to have functionality different from a standard mouse. For example, they may want to turn a touchpad into a keypad, where touching the surface in certain areas produces keystrokes. For those customers (OEM) who use a touchpad module to create their own device, this pretty much amounts to having a customized driver. Instead of having to build a new driver, they could simply edit the configuration file. > >>> Any help will be sincerely appreciated. >> >> The kernelnewbies mailing list and wiki covers the above topic in great >> detail if you wish to understand why you should not be doing any of the >> above from within the kernel. >> > Thank you for pointing me to kernelnewbies. I realize it's premature to argue before I have read their arguments against doing these things in the kernel, but the first objection that crosses my mind is this: I can do it in Windows.
