Error: 32

[AnimeshSaraswat]

I ran both auto pair and the long procedure to connect the devices,
but it always gave an error saying "Broken Pipe" and "Error: 32"
I have a device Logitech M185.

I got the same error, using Logitech M310 and Ubuntu 14.04.03

You will get EPIPE (Broken pipe) errors when you write to the wrong device. Have you tried ltunify (https://lekensteyn.nl/logitech-unifying.html#ltunify) or Solaar?

[AnimeshSaraswat]

@Lekensteyn both the software's you mentioned above are meant for the UNIFYING receiver, where as this thread mentions how a NON-UNIFYING receiver as well as a UNIFYING receive can be used to connect with other mouse. Unfortunately I tried both of them and have been unsuccessful in achieving the desired result.

[Lekensteyn]

@AnimeshSaraswat Doesn't matter, the base protocol seems also applicable for non-unifying. Please try removing the receiver and reinserting, run the dmesg | tail -n20 command and copy the last entries after inserting the receiver. It will probably mention some /dev/hidrawX devices.

Maybe this will help? I am having the same issue - looks like several USB devices with the same name?

@klimmiks it looks normal, you have one receiver and one device paired to the receiver.

Instead of hiddev0, according to the suggestion of @Lekensteyn, I use hidraw1 and it works on non-unifying receiver!
