Microsoft 600 Wired Keyboard

[AdamHayton]

Any idea why this wouldn't work with a Microsoft 600 Wired Keyboard?

Tried ENFORCE_PORTS and ENFORCE_KEYBOARD_BOOT_PROTOCOL

The keyboard is unresponsive and typically stays with num,scroll and caps lock illuminated.

It does have a few media keys at the top, but apart from that is is standard.

I'll try and get hold of some other keyboards to test in the meantime.

Thanks

I ordered from Elecrow, tasking inspiration from #172 I tried with a simple unpowered usb hub, and it works!

Let me know if you need anything else.

Thanks

I also had the same issue with one of my mice, however, this is more much intermittent and it will work when plugged directly in without needing the usb hub between the two.

If I plug in via the hub, then the keyboard it will work. If I then unplug the keyboard from the hub and plug back into the hub, it will not work.

If I connect the keyboard to the hub and then plug in the hub, it will work consistently.

I'm assuming that the hub is changing the timing and or resistance. For reference this is it: https://www.amazon.co.uk/BOULTON-Splitter-Extension-Adapter-Keyboard-Grey/dp/B0CQRN5CB9?th=1

Hope this helps.

This is likely something with the PIO USB compatibility / TinyUSB if unpowered HUB makes it work. The plug-back into a HUB issue I remember seeing, that was some hub implementation issue with the USB stack. I don't have the hardware involved so debugging would be next to impossible, that's why I'd advise to continue using the hub. Reminds me of a funny anecdote from an Amiga premiere event in 1985 when Andy Warhol was told not to use the flood fill because it crashes (of course he ignored them).
