[108495.369056] usb 5-1: new full speed USB device using ohci_hcd and address 3

[108657.154954] usb 2-4.7: New USB device strings: Mfr=0, Product=0, SerialNumber=0

I just noticed this: the device is claimed by OHCI, then ~150 seconds later(!)
it disconnects and then gets claimed by EHCI, presumably while it's in use.
