USB hub slows down Lenovo BIOS and boot

I just got a Lenovo Thinkpad L580.  When I have my dodocool USB-C hub plugged in, boot is VERY slow, and it will just sit there with a non-blinking cursor in the top left corner of the screen for ages.  Also, when I go into the BIOS setup, if I plug in my USB hub it locks up for maybe 10 seconds.  There seems to be something very wrong with the way the BIOS deals with USB connections.  :-(

Re: USB hub slows down Lenovo BIOS and boot

Hello Jez,


here we had a similar USB related problem, we could solve it (at least partly) through disabling USB UEFI Support, under BIOS Config --> USB.


Maybe it helps.
