The double free occurs because the function uhci_submit_urb
(\reactos\drivers\usb\nt4compat\usbdriver\uhci.c:1327) frees memory on error,
and the calling function hub_event_dev_stable
(\reactos\drivers\usb\nt4compat\usbdriver\hub.c:1171) does the same. 
I think it's appropriate to let the calling function handle the free, since it
frees it the way it is has allocated the memory, while uhci_submit_urb frees
the memory as a list entry (RemoveEntryList((PLIST_ENTRY) purb)).
