Hi all.

I need to develop the library to communicate with the USB HID device. However, I follow the sample and when I want to open device in /dev/usb/hiddev, I only realize the device hiddev file is not create.

Anyone know how actually the udev working?

Below is the step that I tried.
I plugged the HID hardware and I use lsusb command and can found the hardware device and comfirm is a USB HID device.

I have tried to find in /dev but can't see the hiddev file as well. Even the /dev/usb folder also does not exist.

I find in ubuntu 10.10, 11.10 and fedora /dev also don't have the hiddev file, is it got some changes that I don't know?

have you checked the device drivers for usb and hid? Are they loaded?

Thanks for reply.

Can you tell me how to check for it? Sorry I am newbie for this.

for example lsmod

It is loaded.

usbhid 36882 0
pcnet32 31535 0
floppy 54311 0
hid 67742 1 usbhid

The hid-core do not add device in old version kernel
