 In my case with Parrot Linux it was a case of Interrupt conflicts. IRQ#18 kept being disabled by the system. After disabling the EHCI Handoff in the BIOS,ehci_hcd:usb1 was replaced with ehci_hcd:usb2 and the mouse lag after a random period of time stopped.

You can view your interrupt assignments with:
cat /proc/interrupts

Mine changed from:
18: IO-APIC 18-fasteoi ehci_hcd:usb1, pata_jmicron, ata_piix, uhci_hcd:usb8
to:
18: IO-APIC 18-fasteoi ehci_hcd:usb2, pata_jmicron, ata_piix, uhci_hcd:usb8

And the problem was resolved.
