Keyboard/Mouse work with 2 active devices, but only one peripheral works with 1 active device #101

Closed Francommit closed 2 weeks ago

Using two devices, the device works perfectly. As soon as I turn off one of the devices, I've found that I either only get the mouse OR the keyboard functionality.

As soon as I turn on the other device, the device that was previously not working, begins to work.

You may choose a "main" device (either A or B) and put both - mouse and keyboard - on a hub and connect it on the side of this "main" device. Then you can use mouse and keyboard without the other port used.

Sorry what do you mean by 'connect it on the side' ?

Should I put the USB hub into the keyboard or mouse slot?

Actually not sure I do understand. What's putting a USB Hub going to do at all?

techge commented 3 weeks ago

The thing is that normally the mouse is powered by device B and the keyboard by device A. So when one of the devices is powered off, the corresponding hid device is powered down, too. Therefore, the deskhop was re-configured so that one pico can power and control both when they are attached with a usb hub. So if you connect the deskhop to device A and connect both - the mouse and the keyboard - to a usb hub and the usb hub to the "keyboard" port, then both are always powered when device A is connected.

I hope this explanation was of help.

Sorry for being late to the party, @techge summarized it very well. I didn't really expect this scenario to be a thing, and I wanted to keep it as simple as possible. Will try to provide an alternative in future board revision.
