Unable to suspend laptop

Question

The laptop does not suspend when suspend key is pressed, it is not suspended even when I type

command systemctl suspend -i .

One of the usb ports does not work and usb2-port3 over-current condition message comes at dmesg.

OS: Ubuntu 20.04 ;
HW: DELL Latitude

The laptop successfully goes to sleep in Windows 10 mode(dual boot).

Following is the journalctl log regarding suspend

Please mention which Ubuntu version you are using. And which hardware. Add this information to your question **NOT** into the comments. Open a terminal and type `lsusb`. Copy the answer and add this to your question as well — kanehekili, May 29 '21 at 21:03
The error -16 is "Device Busy". Some process is still using `usb1`, some process is still using `usb2`, and didn't shutdown. — waltinator, May 29 '21 at 23:34
@waltinator how to find which process are using usb1 and usb2 and how to prevent usb1 and usb2 from being used. And by the way shutdown happens normally without any problems , only suspend and hibernate are not working. — A B, May 30 '21 at 08:43
There is a relevant bug report for xhci_pci kernel module: https://bugzilla.kernel.org/show_bug.cgi?id=116761. Try `rmmod xhci_pci` before suspend, xhci_pci kernel module can fail to suspend failing overall suspend of the system. — ks1322, Oct 11 '21 at 10:16
