USB Devices
 

Hello,

I'm trying to write a simple background process that reads input from a USB magnetic card reader. In most linux systems you can find the device in /dev/input. Unfortunately its not there. Does anyone have any suggestions as to how I could read this USB card readers input stream? I do have a /sys/class/input directory for it, but there are a ton of items in that directory and I don't want to break anything. The reader is a GIT usb card reader and I have had no luck from contacting the company thus far.

Run with the reader disconnected, the plug it in and run again. What's the difference? If your distro understands it, you should see it identified properly which is a start.

Play Bonny! :hattip:

It finds it..


[ 195.863911] input: GIT GIT USB READER as /class/input/input2
[ 195.864259] generic-usb 0003:1234:5678.0001: input: USB HID v1.00 Keyboard [GIT GIT USB READER] on usb-0000:00:0f.4-1/input0


But where is my data stream? I've scanned through /class/input/input2 a ton, but Im not sure what I'm looking for exactly.
