No keyboard, no mouse working

[pierreact]

Description

Hello,

I've installed tinypilot on a raspberry pi 3, everything works but keyboard and mouse.

# echo asdf | /root/hid_gadget_test/hid_gadget_test /dev/hidg0 keyboard
    keyboard options:
        --hold
        --left-ctrl
        --right-ctrl
        --left-shift
        --right-shift
        --left-alt
        --right-alt
        --left-meta
        --right-meta

    keyboard values:
        [a-z] or
        --return        --esc
        --bckspc        --tab
        --spacebar      --caps-lock
        --f1            --f2
        --f3            --f4
        --f5            --f6
        --f7            --f8
        --f9            --f10
        --f11           --f12
        --insert        --home
        --pageup        --del
        --end           --pagedown
        --right         --left
        --down          --kp-enter
        --up            --num-lock

/dev/hidg0: Cannot send after transport endpoint shutdown

# modprobe g_hid
modprobe: ERROR: could not insert 'g_hid': No such device

What's the behavior that you expect?

Keyboard and mouse to work

What's happening instead?

What described above.

What are the steps to reproduce this behavior?

1. Install raspbian bullseye
2. Install tinypilot
3. Connect cables to a compter to be managed (Tried a PC and a mac on different USB cables)

Thank you!

Thanks for reporting this!

Unfortunately, TinyPilot is not compatible with the Pi 3. See https://github.com/tiny-pilot/tinypilot/issues/911#issuecomment-1040720968 for additional details.

I'm surprised you were able to install, as the installer is supposed to error out if it detects a Pi 3. How did you install TinyPilot?

Can you share the output of this command cat /proc/cpuinfo?

Sure, thanks for your reply, I wondered why for the life of me I couldn't get things working. Seems I got my answer now, will order a pi4.

@pierreact - That's strange. The installer should have caught this.

Did you install with the get-tinypilot.sh script or some other way?

I am also able to install tinypilot using "get-tinypilot.sh" into my RPI 3

But I see that unfortunately RPI 3 models don't have proper I/O for OTG , therefore it is not possible to emulate keyboard and mouse in anyway.

It would be much appreciated if we could somehow solve this mouse/keyboard forwarding with a workaround or another approach.

Many thanks for this great contribution regarding tinypilot overall <3 !!

@UmutAlihan - Thanks for the kind words.

Unfortunately, I don't think there's any feasible workaround on the Pi 3. If the hardware doesn't support it, there's not much we can do from the software.
