Looking for help debugging

[Reletiv]

Here i am building a usb to ps/2 converter because my HP KVM switch does not like my NanoKVM usb keyboard mouse. I am looking for help in debugging since i have no idea where to start

Currently trying to get it to work on an old HP elitedesk, does not work, neither does it on the kvm.

here are some images of my assembled prototype, maybe its hardware, maybe not:

i do get the following serial output with a hp keyboard attached: 19:16:19.929 -> ps2x2pico-2.1 19:16:19.929 -> Setting defaults for keyboard 19:16:19.964 -> scancodeset set to 2 19:16:19.964 -> kb > host aa 19:16:19.964 -> ms > host aa 19:16:19.964 -> ms > host 00 19:16:20.056 -> Blinking keyboard LEDs 19:16:20.641 -> 19:16:20.641 -> HID(1,0,keyboard) mounted 19:16:20.641 -> VID: 0d62 PID: 913e 19:16:20.641 -> HID has 1 reports 19:16:20.641 -> HID(1,0,keyboard) registered for reports 19:16:20.641 -> 19:16:20.641 -> HID(1,1,none) mounted 19:16:20.641 -> VID: 0d62 PID: 913e 19:16:20.641 -> HID has 2 reports 19:16:20.641 -> HID(1,1,none) registered for reports Also clicking the space button etc results in some output so the keyboard seems to be detected. With the logic analyser i can also see some data coming out of the gpio pins 19:16:25.299 -> kb > host f0 19:16:25.299 -> kb > host 11 19:16:25.345 -> kb > host f0 19:16:25.345 -> kb > host 29 19:16:25.527 -> kb > host 29 19:16:25.616 -> kb > host f0 19:16:25.616 -> kb > host 29 19:16:25.877 -> kb > host 29 19:16:26.286 -> kb > host f0 19:16:26.286 -> kb > host 29 19:16:26.597 -> kb > host 29 19:16:26.686 -> kb > host f0 19:16:26.686 -> kb > host 29 19:16:26.804 -> kb > host 29

I've not tested the Pico W, but I think its ok?

Can you post a screenshot of the logic analyzer?

I bought a normal pico today, but i still have the same issues. I will record some signals this weekend

@Reletiv did you ever find your problem?

I built one for a friend, and it looks good, the keyboard works, but not the mouse.
