Hello:

"Error:Module usbhid does not exist in /proc/modules".I modified kernel by
make menuconfig.In Linux Kernel Configuration,I modified Device
Drivers->HID Devices->select {M}Generic HID support
                             [*]/dev/hidraw raw HID device support
                             <M>USB Human Interface Device (full HID)     
support
                             [*]/dev/hiddev raw HID device support


But it did not exist in /proc/modules.Anyone can tell me what I can do
.Where error?
