Ducky Keyboard USB Rapidly Disconnecting and Reconnecting

Ask Fedora

Hello,
I am hoping to get some help. I am new to Linux but can find my way around if need be.
I have a Ducky Shine 7 keyboard that works great on Windows and my laptop running Pop OS. Works great without issues there.

However on Fedora 43, the keyboard rapidly disconnects and reconnects:
Pop up error shows “USB Device Detected” and next second pops up “USB Device Went Away” this is an endless loop and the keyboard will not work.

I am not sure what to do?
I have tried updating firmware for the keyboard and neither updating nor resetting firmware for it has worked. No USB slots work for this keyboard.

Other USB keyboard I have works fine.

Post the section of the journalctl output which shows this behaviour taking place, as pre-formatted text; my initial suspicion will be overly aggressive power saving on the USB port the keyboard is using, but without the journal output we can only guess.

Hi thank you!
I had to do a bit of research on what command to use for usb activity, I used command

journalctl -k | grep usb

Let me know if you need a different command

This device is directly connected via a cable, or is it running over a wireless link and a dongle?

The -71 errors which is produces is a USB protocol error, according to the kernel headers, which makes it assume this electrical (low quality cable, low quality noisy USB dongle, iffy USB 1.1 port, etc).

You can test this by running journalctl -f in a CLI window and plugging in whatever kit you are using into whatever USB ports you have available on your tin. Does everything produce the same responses in the journal log?

The Ducky is a wired direct USB connection. Solid and no issues on other systems. I had also plugged in another mini bluetooth keyboard to run the command which might have caused some interference in the log.

I have also just now tried a different mechanical keyboard that belongs to my friend and it works fine on my fedora system. Seems to be just this keyboard and fedora not getting along

Here is
journalctl -f

I plugged into each USB port on my tower. I keep getting error -71 on each port as well as

Can you exchange the cable in use for this keyboard - I don’t know if this cable is fixed to the keyboard or is removable, but swapping it for a known good cable might shed some light on the matter. Using a black USB2 port on the motherboard itself would also be beneficial, and avoiding any USB hub (if you use one).

The keyboard is “good” as in it has power, and it’s communicating with the kernel to identity itself, but the -71 errors are EPROTO - Error in Protocol which implies that it’s not following the HID protocol fully or the signals its sending are being corrupted due to a poor cable, bad shielding, no ferrite cores, a poor connection at the USB plug, etc.

You could try passing the parameter usbcore.old_scheme_first=Y to the kernel on the grub boot selection screen (highlight a kernel, hit e, past that onto the line which contains rhgb and quiet and then pressing F10 to boot the kernel with that parameter applied).

It’s a one time change, and will not persist across reboots so if it doesn’t help you’ve lost nothing and if it does help we can how you how to add it to every kernel, every boot, forever.

Hi Steve,

usbcore.old_scheme_first=Y

is a working fix! I typed in the command using the old non-ducky keyboard that was working with this system, booted with that command and then unplugged the working keyboard and plugged in my Ducky keyboard and it works!

I also notice that if I boot from the bios while it is plugged in I can get it to work but not after a restart.

If you have a solution for a permanent fix I would appreciate your help! thank you so much so far! :slight_smile:

OK - in order to make this permanent we use a tool named grubby. (man grubby for the details)

We can to add that parameter to every boot entry for each kernel installed on this system and all future kernels - we can do so via sudo grubby --update-kernel=ALL --args=usbcore.old_scheme_first=Y

If you then reboot and hit e again, you should see that every kernel already has that argument slapped onto the end of it, and all future kernels will also receive it.
