Hi
I apologise if it is a simple task. I have a USB barcode scanner that
show up as an HID keyboard device. I am using it with linux-2.4.20 and a
slightly modified RedHat-8.0. The problem is that it is working as a
keyboard device so whatever I scan shows up as keyboard input (inserted
into keyboard input stream). I have been trying to use it not as a
keyboard device but as a serial type character device so an application
can read what it scans. I have not found any way of doing it using the
USB devices that are part of the kernel.
Can anyone point me to the right direction. I would like it to be a
device file that I can open from inside an application and read the
scans using something like fscanf(). Below is the log for usb and
hotplug. And below that I will include the device output from usbview.
