I’m messing about, writing some code that simulates keyboard/input device events to automate various things under linux. I’ve been using /usr/include/linux/input-event-codes.h as a bit of a reference for what key-codes are available. Within that header, it mentions that some of the content is based on a USB standard: I assume it’s referring to an old version of this HID User

slcand error : Inappropriate ioctl for device
I want to use can interface with slcand, but I have a problem. To link can device(canable) with slcand, I make symbolic link with udev-rule SUBSYSTEM==”usb”, ENV{DEVTYPE}==”usb_device”, ATTR{product}==”canable gs_usb”, ATTR{serial}==”002900355934570820373433″, SYMLINK+=”cantest2″ It successfully made symbolic link “/dev/cantest2”. However, when I use command “sudo slcand -o -c -s8 -F /dev/cantest2 can8”, I got a error message enter image description here I
How would I reproduce the functionality of the Windows winusb driver on Linux? Do I even need to?
I need to implement an application on Linux that drives a USB connected device (a medical instrument). The application will be written in C++ (2011 standard). The current application is written for Windows 10 in C# and uses the standard Winusb driver enumerated for the device. I have a complete protocol specification for the commands and the events/interrupts coming back.
Immutable names in /dev/disk
There are four entries in /dev/disk which I am interested in. by-id by-label by-path by-uuid Which of the entries contain immutable names for physical drives? By immutable, I mean that the name shouldn’t change if I change the usb/pci port used to connect to the drive. destroy and create partitions (GPT). move from one computer to another (external hard-drive). For
Linux : how to transfer data through USB bulk endpoint of cdc-adm driver from userspace
I am a beginner to Linux drivers and I started with writing an application for a cdc-acm based USB device in linux. Therefore, I have used the cdc_acm driver. The USB device that I am using has 2 Bulk endpoints (read and write) and one interrupts endpoint. Now, my question is whether all these endpoints operate on the same /dev/ttyACM0
Blocking USB HID in Linux

Serial Input in Ubuntu, Usb to serial converter (Pl2303 – Prolific) not working in ubuntu 18.04
I am trying to read input from a Electronic weighing scale (Weigh sensor) connected to Ubuntu enabled UDOO board using a Prolific PL2303 serial converter cable (CA-US9), but am unable to read any input from the sensor. To monitor the input I have tried using (Coolterm & GTKTerm), assuming an issue with the driver I have referred and tried updating
Yocto Project usb sensor access
I’ve never worked with the Yocto Project, and barely knows what it is. But I’m investigating the possibility to use a Simatic 2040 as a gateway between an USB hall sensor and industrial PLC network. The sensor that we want to use is this one. It’s designed to use with an Windows desktop PC, connected via USB. Now my main
Controlling Jabra 710 USB speaker volume from linux host
I am using Linux (2.6.39 kernel) and trying to find a way that would allow me to send volume increment/decrement commands from my host Linux OS to the Jabra device. I saw this functionality is possible both in Windows and Ubuntu, where controlling of the volume from the PC alters the Jabra volume. I am able to accept Consumer HID
Bash – How to run code whenever USB device is connected
I am writing a bash script to automatically detect when my USB keyboard is plugged into my laptop (running Ubuntu 14), so I can change the keyboard layout automatically. Here is my code so far (I got it from another post on Stack Overflow so I’m not 100% sure how it works) I have got this to run on startup
