Even if it were a temporary condition then an immediate retry is rather pointless. Retry after a slight delay might make some sense. Of course, if this is the pagedaemon trying to write out pages in order to generate some free kernel memory all is lost as soon as the usb subsystem need to allocate memory in order to perform a transfer.
