Not able to communicate with device using usbmon

v3gard · 12-03-2014, 10:14 AM

I posted a question at stackoverflow a few days ago where I asked for help regarding usbmon. My problem is that I have a USB HID device that I want to interface with on my Linux system that I am unable to communicate with through usbmon.

tl;dr; I have connected a HID device to my Linux system, loaded the usbmon driver, and found a file descriptor to my device. However, when I read the file for events, usbmon provides no output.

Any ideas?

Try running lsusb in your terminal.
Does lsusb see it?

Is it a game controller or camera?

If it's related to dual monitoring, sorry I can't help with that.

Thanks for the reply.

Yes, I have run lsusb and verified that it has been detected. I mentioned that on my SO post in case you have not read it yet. It is not a camera nor game controller - but a Dream Cheeky Big Red Button. As a side note I have also verified that the device is working in Windows, where I have official drivers.

edit: relevant output from lsusb

Code:

Bus 004 Device 002: ID 1d34:000d Dream Cheeky Dream Cheeky Big Red Button

Your Welcome-

I wish I knew why usbmon isn't providing you with any output.

I see that the functions included are:
"Boom", "I-Inch Working", "Punch Up", "Web key" and "Take a Break"

That Dream Cheeky Big Red Button looks like a great way to stop your self from destroying your computer when it gives you stress or troubles.

Maybe try the dmesg | grep -i tty command and see if that provides output for you device?

Maybe another member will know how to obtain output for that device.
I'm not familuar with this device, sorry:-

Dmesg doesn't report anything unfortunately except from when I connect or disconnect the device.

The official software for this device is really bad, haha. I plan on using the button as an emergency shutdown device for my server and attached devices.

Code:

[82446.764995] hid-generic 0003:1D34:000D.0007: hiddev0,hidraw0: USB HID v1.10 Device [Dream Link DL100B Dream Cheeky Generic Controller] on usb-0000:00:1d.1-1/input0
[82458.335473] usb 6-1: USB disconnect, device number 7

Even with debug mode on, I get nothing when I press the button on the device or open/close the lid.

Code:
