This is a long shot in this forum but I've been trying to work this out for weeks. A couple of weeks ago I tried the VLC forum and no help other than "It ain't us, it's linux HID".
The basic problem is:
I'm trying to install VLC (or any video viewer, really) to enable my wife to carry out video transcription on linux (specifically, Ubuntu).
All works as expected except I cannot get a USB foot pedal to work with VLC (required to Play/Pause, Rewind and Forward). An installation of Express Scribe (only runs audio) allows me to go through a simple setup where it asks for a pedal press, I press a pedal and it all works. Given the complexity of VLC I expected a similar feature but it's not there.
For Windows I could buy a piece of software that would do the trick but nothing for linux (and I would not expect it to be necessary anyway - a script or two should suffice at most).
The VLC forum suggests that, because it's HID (Human Interface Device) I need to work out how to run that into VLC. In my view, laziness on the part of VLC - how difficult can it be to do this at the interface level?
I've played with lirc and a couple of other HID-type interfaces but can't work out how to do it. This may simply be lack of knowledge/experience on my part.
Running cat on hiddev0 comes up with a 24-byte string for each pedal action - no idea why so many bytes nor how to make use of them. "Put the pedal code into the VLC short-cuts" was one piece of advice but I can see no way of altering the "hot-keys" except by pressing a combination of keys on an ordinary keyboard. There seems to be no facility on VLC to enter arbitrary key-code strings.
I've searched online in a number of different ways for a solution and the appearance is that no one wants to do this - which I can't quite believe. Although even Express Scribe no longer update their software for linux - plenty of old versions offered on download sites but not the latest version.
If anyone has any ideas they would be gratefully received.

I did a search for USB foot pedal VLC "Linux"
The first few links were either your posting elsewhere or unhelpful, but after that there was a link leading to software that may solve your problem (at a cost).
[softwaretopic.informer.com...]
"It makes USB transcription foot pedals compatible with VLC Media Player." with a link to
[vlc-foot-pedal.software.informer.com...]
It's classed as Shareware but costs $49.99

Thanks.
Those sites are lying - all items listed are, if you follow through to the "home" sites, a single package written for Windows. I've seen that particular package several times on a lot of web sites. :(
Thanks for trying, anyway. :)

A long shot, but does any of this help:

https://wiki.archlinux.org/index.php/Extra_Keyboard_Keys
is it that you need to map scan codes to keycodes?

Thanks for the leads, graeme! I'll work through them over the next few days and get back to you. :)
