The keyboard I own after a little while of use (at least a few minutes) disconnects. It will even disconnect while in use in the middle of typing and not just after being idle. It can be resolved by unplugging and plugging the device in again. The keyboard is Obins Anne Pro 2.

This does not occur with other keyboards that I own. It also does not occur with this device on a Windows laptop that I own. I emailed the keyboard manufacturer, but didn't get a response.

I have tried the following

  • Different USB cable
  • Different USB port
  • Looking in BIOS for USB power saving settings or anything that seemed usful.
  • Updating keyboard firmware through the software that ships with the keyboard.

The device shows up in lsusb as Bus 001 Device 029: ID 04d9:8009 Holtek Semiconductor, Inc.. It also still shows up after the device stops responding. dmesg | grep usb does not show anything when the device disconnects, only when the device originally connects. Here is the output when it connects:

Any advice would be appreciated.

My machine is running Ubuntu 19.10. This issue has persisted through software updates though.

I have Anne Pro 2. Using it on macOS and Windows, I got no problem.

When using it on Arch Linux, it stops working after some inactivity (5 minutes). If I keep continually typing on it, it works without any problem.

Reconnecting the keyboard works. I think the issue might be with firmware + Linux driver. The problem might be related to power saving mode (inactivity triggers some logic?).

I upgraded to the latest Alpha firmware using obinskit tool. Now the problem with USB re-connection is gone. There are often other bugs related to TAP layer, but that's a different story.

I switched to the latest firmware and replaced the USB cable. All of my problems are gone. I believe the thing that helped most was replacing the cable.

As a workaround, I found that if you turn on ObinsKit in the background, the keyboard will not disconnect anymore.
