Subject: Unable to enumerate USB device messages back in 3.7-gitX

Alan,

Unfortunately, those pesky messages have returned since the 3.8 merge has 
started. Using 'git describe', my system is v3.7-8805-ga4f1de1. The USB-related 
messages logged are as follows:

  usbcore: registered new interface driver usbfs
  usbcore: registered new interface driver hub
  usbcore: registered new device driver usb
  ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
  ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver
  ohci_hcd 0000:00:02.0: setting latency timer to 64
  ohci_hcd 0000:00:02.0: OHCI Host Controller
  ohci_hcd 0000:00:02.0: new USB bus registered, assigned bus number 1
  ohci_hcd 0000:00:02.0: irq 17, io mem 0xfc486000
  hub 1-0:1.0: USB hub found
  hub 1-0:1.0: 5 ports detected
  ohci_hcd 0000:00:04.0: setting latency timer to 64
  ohci_hcd 0000:00:04.0: OHCI Host Controller
  ohci_hcd 0000:00:04.0: new USB bus registered, assigned bus number 2
  ohci_hcd 0000:00:04.0: irq 16, io mem 0xfc487000
  hub 2-0:1.0: USB hub found
  hub 2-0:1.0: 5 ports detected
  usb 1-4: new full-speed USB device number 2 using ohci_hcd
  usb 2-2: new full-speed USB device number 2 using ohci_hcd
  hub 2-0:1.0: unable to enumerate USB device on port 5
  hub 2-0:1.0: unable to enumerate USB device on port 5
  <plus a lot more of the above>

I have not yet had time to bisect the problem, but I will do so ASAP. I mostly 
want you to have a heads-up that the problem has returned.

Thanks,

Larry
