I have a eDIO USB Multi Remote Controller( a Infrared Reciever)
I am trying to connect the Remote COntroller so that it recieves the
keystrokes sent by the remote.
The controller is detected as a HID device. Here are the details from
the lsusb -v command

I can also the device in the dev folder with an event created
pi@raspberrypi /dev/input/by-id $ dir
usb-Cypress_Semiconductor_eDio_USB_Multi_Remote_Controlle-event-if00
The event handler associated with it is as follows as seen from the
following command.
pi@raspberrypi /proc/bus/input $ cat devices
I: Bus=0003 Vendor=147a Product=e001 Version=0110
N: Name="Cypress Semiconductor eDio USB Multi Remote Controlle"
P: Phys=usb-bcm2708_usb-1.2/input0
S: Sysfs=/devices/platform/bcm2708_usb/usb1/1-1/1-1.2/1-1.2:1.0/input/input2
U: Uniq=
H: Handlers=event0
B: PROP=0
B: EV=1
The problem is when I am trying to read the output from the event
handler created for the device.The first keystroke is registered but
the subsequent key strokes are not displayed by the CAT command.
pi@raspberrypi /dev/input $ cat event0 | xxd
0000000: e007 9450 9476 0900 0000 0000 0000 0000 ...P.v..........
Please suggest me what can I do to get the device working. Pressing
any keys after the first keystroke doesn't return anything unless the
device is replugged.
Please suggest what needs to be done to fix the issue.
