Auto-Detect issue

[personaobscura]

My computer has developed a lag during startup. When the boot process gets to Auto-detecting USB Mass Storage Devices there is a noticeable pause whereas there was none before. It is not consistent, sometimes it happens and then sometimes it doesn't. Is this a problem and what can I do about it?

- If you unplug your external usb devices, does it lag?
- update your bios, if possible
- select primary boot as hard drive, and do not have any other boot devices
- disable legacy usb support

Hard drive selected no other boot devices Disabled USB legacy support and the delay is gone. Thanks for your time!
