Diva mp3 and 2.4.19+ usb-storage: kernel: hub.c: connect-debounce failed

My Diva Mp3 player works wonderfully on 2.4.18 but failed to work on 2.4.19. 
I'd hope the problem would be solved, but I just tried 2.4.20 and the 
problem persists. Under 2.4.{19,20} it reports "kernel: hub.c: 
connect-debounce failed" when I connect the device to USB. I suspect it has 
something to do with this function in hub.c or the default time-outs.
  static int usb_hub_port_debounce(struct usb_device *hub, int port)
