Hello, Is there some way to disable input event device ? Maybe a way to disable its irq usage ? I actually rather do that from shell, not from kernel, because the kernel source is not available, and I thought that issue is also relevant in the forum. Thank you, Ranchu

But the Linux kernel source is available, why not just not load the driver for the device you are wanting to not be "connected"? thanks, greg k-h

Hi Greg,
I am trying to do that from android, in a device where the kernel source is not available :( ..... By the way, I think the company (No.1 for D6 smartwatch) should supply the source because kernel is GPL , Right ? Therefore I try to achieve it by doing some actions in shell. Regards, Ran
thanks,

Is blacklisting it an option?? Regards, 2016-12-03 15:18 GMT-02:00 Ran Shalit <ranshalit@gmail.com>:

I think not, because blacklist is only for loaded modules, Right ? While in android Linux, seems that all modules are built inside kernel image...

Some more information about the touch device : I have sysfs entires for the touch device in kernel as following: /sys/devices/virtual/input/input2/event2/ root@mako:/sys/devices/virtual/input/input2 # ls capabilities event2 id modalias name phys power properties subsystem uevent uniq root@mako:/sys/devices/virtual/input/input2/event2/device # ls capabilities event2 id modalias name phys power properties subsystem uevent uniq root@mako:/sys/devices/virtual/input/input2/event2/device # cat name touch_dev Thanks, Ran

Yes it is, please contact the company about this to get the source code for your device. If you have problems with this, please try the Linux Foundation's form for this type of thing at: https://www.linuxsources.org/content/open-compliance-directory-request-conta... as it works really well.
Therefore I try to achieve it by doing some actions in shell.
Disconnect the device from the driver by writing the device id to the "unbind" sysfs file for the driver that is controling the device. Examples of how to do this in detail should be on the web somewhere, I think I wrote a lwn.net article about this a long time ago... good luck! greg k-h

Hi, Just wanted to update the the unbind method (for disabling device such as touch screen) works perfectly with linux in general, and in android Linux too ! Many Thanks, Ran

Hi, Just wanted to update: the unbind method worked with some kernels, but not all. In one device&kernel, after doing the unbind, on entering event, the device immediately has boot itself ! Yet , luckily, I have found another method which works: chmod 777 /dev/input/eventX rm /dev/input/eventX It works :) ! Thanks, Ran
good luck!
