Using Speed Editor does not reset screen saver timeout on Linux. This leads to monitors going blank suddenly in the middle of edit, and forces to take hands of the panel to touch the keyboard or mouse to reset the screen saver. Small thing, but annoying.

Second bug may have more serious consequences: when screen lock is active, SE can still control Resolve. This may lead to someone unintentionally (or not) making changes to the project when the editor stepped away from the desk, and locked the workstation to keep it safe.

Yeah, you'd think the OS would see those operations as User Input.

SE exports several interfaces on USB. One of the m is HID (Human Interface Device USB class), but I have not seen any interesting activity on if. All events are coming from an application specific interface, and the windowing system knows nothing about it. Had the events been sent from the HID, most likely the problem would not exist.

@Jacek : Mind pastbinning a lsusb -vvv ?

I haven't spent much time on digging into the communication from SE, but the events look easy enough to decode, to use the console for other applications.

Wait only the HID interface has any endpoint ... so that's the only way it'd exchange data ....

Looks like you're right. There is data coming from /dev/usb/hiddevX
