Comment (by jcardona):
Captured another instance of the problem, available here:
https://cozy1/~javier/debug_olpc_usb/resume-pings-stop-during-
enumeration.usb
You will need the USBMobileHS software application available for free
(prior registration) on LeCroy's website:
http://www.lecroy.com/tm/Library/Software/PSG/usbmobile.asp?menuid=8
Here we see that the first {{{GetDescriptor}}} transfer fails:
{{{
Transaction. 0: Setup request is ACKed by device.
Transactions 1-28: In packets, NAKed by device.
Transaction 29: Device sends 18 bytes of descriptor.
Transaction 30: Host sends 0 byte packet to device (high level ack),
which is NACKed
Transaction 31-34: Host sends 4 ping packets which are NACKed.
}}}
Then no more activity for 3ms, after which the bus enters suspended state.
