I live in Spain and since the electrcity blackout on 28/04, I started facing unraid UI hanging and slowliness. Checking the system logs a lot of logs "unraid kernel: usb 2-2: device not accepting address 2, error -62" showing up. No usb listed on bus 2, port 2.

After a lot of troubleshooting:

- try different usb stick to boot - same logging error
- boot in safe mode - no error
- try different usb port - same logging error
- boot with none usb attached (apart of the boot drive) - same logging error
- upgrade unraid from 6.12.6 to 6.12.15 - same logging error

Right now the only usb devices plugged in are the unraid boot drive and the sonoff zigbee stick. 

These stacktrace is showing every 3 minutes:

This is likely the issue, for some reason the MSI RGB device and Connect have an issue now, try uninstalling the Connect plugin and reboot, then see if the problem goes away.

I just uninstall the Unraid Connect plugin and reboot the server and yeah, so far the issue seems no more present.. No error logs neither UI hanging... 

Many thanks for the help!

On the long-term what do you recommend I do? Keep the Unraid Connect uninstaled until a new version (with a posible fix) is available? Or there is something I can do in the meanwhile ?

This issue has been reported to LT, so hopefully they will fix it soon.

ok, glad to hear it. Many thanks!

Please re-test with the latest version of Unraid Connect. We’ve updated the internal USB listing logic and believe this should be resolved.
