Interesting. A couple of years back, there were a few reports on strange usb
behavior on Macbooks that turned out to be a hardware problem, a bad internal
usb connector. Could that be the case here?
Since ENOSPC is pretty rare, narrowing it down code-wise seems possible. It
could for instance be this path happening:
usb_submit_urb
usb_hcd_submit_urb
hcd->driver->urb_enqueue
ehci_urb_enqueue
intr_submit
qh_schedule
fail
