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.

  • Ubuntu 19.04 is EOL or end-of-life (fridge.ubuntu.com/2020/01/23/…) thus off-topic on this site (askubuntu.com/help/on-topic) unless your question is specific to help moving to a supported release of Ubuntu. Use a LTS or long-term-support release if you don't like release-upgrading every 6-9 months – guiverc Mar 22 at 2:30
  • This is off-topic, but I'd check your PSU is providing the correct power sustainably and not failing. I've had devices before become 'flaky' due to PSU due to age and the power able to be provided dropping thus devices can fail to operate as designed... If this is the case, you'l have issues as you plug in more devices etc... however your release is EOL & thus off-topic here unless your question is specific to needing help moving to a supported release of Ubuntu. – guiverc Mar 22 at 2:33
  • @guiverc I am now running Ubuntu 19.10. How would I determine whether this is a PSU issue? I haven't had the issue change with more / less devices and it does not exhibit the same behavior with other peripherals. – Aaron Lamoreaux Mar 22 at 4:21
  • PSU = power supply unit; ie. reading your description made me think of hardware issues rather than software configuration. I don't know your hardware, plus it's off-topic here, but it involves a multimeter & open case... Temporarily switching PSU to another one would also be a quick test of my theory.. but again off-topic. as I tend to support older hardware, i tend to read issues I regularly see.. – guiverc Mar 22 at 4:28
