Retry allocations in case of ENODEV

Unlike the read() and write() calls, the ioctl() call
does not wait for endpoints to be enabled, which is
problematic if ioctls() are the first calls on the
usb connection, since they may be called before the
endpoints are set up. We'll have to retry if this
causes them to fail.
