usb touchscreen programming
I am trying to interface an iLCD touchscreen display which has an usb interface. The device shows up as /dev/hiddev0 and I am able to get the device info by ioctl in HIDIOCGDEVINFO. But how do I read or send commands to the device?
I am using RHEL 5 and 2.6.18 kernel. I am programming in C and trying to send commands and read the inputs from the screen. What I would really like to know is if I can use file streaming for that purpose. If not, is there any usb hid driver I need to install?
