[SOLVED] usb3 not working with linux 5.11.14

I recently needed to use my usb3 port on my laptop and saw that it didnt work.
I switched to linux-lts (version 5.10.30-1) and it works there.
I see in pacman kernel update messages about this:
WARNING: Possibly missing firmware for module: xhci_pci
I searched and saw that it had something to do with drivers (or something like that) moving to linux-firmware.
and only solution I found was for Renesas USB controller.
but my laptop desnt have that and has this:
Model: "Fresco Logic FL1000G USB 3.0 Host Controller"

how can I fix this?

Were you actually booted into 5.11.14? This is most often an issue if you updated the system but haven't rebooted or the initramfs isn't what the boot loader points to and you still booting an older kernel.

Make sure the outputs of uname -a and pacman -Q linux match in versions. Other than that, check your dmesg/journal for errors.

yes  I have rebooted.

I have checked it and I dont see any error.
only the message I got for
"WARNING: Possibly missing firmware for module: xhci_pci" when installing new kernel.

UPDATE:
I checked this "lsmod |grep xhci" in the lts and saw this:
xhci_pci               20480  0
xhci_pci_renesas       20480  1 xhci_pci

so I went and installed aur/upd72020x-fw and it worked.
I have the Fresco pcie to usb but but whatever.
it seems to be fixed by this unrelated hardware driver.
