Same happens here with at least two different USB devices:
usb 1-4.3: reset high speed USB device using ehci_hcd and address 5

usb 2-2: reset high speed USB device using ehci_hcd and address 7
usb 2-2: reset high speed USB device using ehci_hcd and address 9
While trying to use an USB device in VirtualBox (sometimes it works, sometimes it does not recognize the device in the VM) it got a little chattier:
