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.
