On on some platforms in BIOS modes, you can use the following command to force USB 2.0 modes for your USB ports: lspci -nn grep USB cut -d ' -f3 cut -d ' -f1 -I@ setpci -H1 -d @ d0.l=0Following is an explanation of what the commands do.The controllers have a register XUSB2PR – xHC USB 2.0 Port Routing Register – at address 0xd0 (check for more details). When the XUSB2PR register is set to 0, it routes all the corresponding USB 2.0 port pins to the EHCI controller and RMH #1. The USB 2.0 port is masked from the xHC and the USB 2.0 port’s OC pin is routed to the EHCI controller. The command setpci -H1 -d @ d0.l=0 does this.needs the vendor and device ID.
