Razer Huntsman [RZ03-0252] opto-mechanical keyboard. I have been using this keyboard for the past 4.5 years.
The keyboard is not getting detected on my PC but is getting detected on other systems which includes other laptops & desktops.
- Checked on both, a system with Razer driver ‘Synapse’ pre-installed & on multiple systems without any pre-installed drivers. Device was detected & worked normally in both cases.
- Tried plugging the keyboard in different USB ports on the motherboard & the front USB port - did not work in either case.
- The device is not working even in BIOS, which is before the OS is loaded, so that would mean that Windows is not causing the issue. Also tested in a secondary OS by installing Ubuntu, did not work even there.
- The keyboard is rated 5V-500mA. I have a Samsung portable SSD which is rated 5V-900mA. The SSD is working fine with the motherboard. So, it means that there shouldn’t be any issues with the power draw.
- Other keyboards - a basic membrane keyboard & a mechanical keyboard (borrowed from a friend) works fine on my PC.
I am unable to deduce the cause of this issue.
