Hi,
I am facing a problem with a USB device. This device is an HID device (i.e. not a keyboard/mouse/joystick).
The Linux kernel is able to recognize the device as a HID device and load the appropriate modules. Using the HIDDEV ioctl's , in my application, I am able to get the vendor indetification, string descriptors and applications that the device supports.
My problem is the following. This device supports a certain protocol using which commands can be sent to the device and it will respond with appropriate information. However, I do not know how to use the available IOCTL's in the hiddev usb subsystem to issue these commands to the device.
I have been successful in writing my owm device driver for this device (i.e. bypassing the hiddev interface) and with this I can issue those commands to the device and get the information. Now I want to do this same thing using the hiddev interface and the facilities it provides.
Any pointers will be helpful.
