Thanks for the suggestions, after a nights sleep and some more experiments it seems that it is an issue with the USB hardware in the 703. If I use a non-powered usb hub between the router and the LinkUSB then all seems well (at least it has been running for a couple of hours without failure whereas without the hub it fails within a few minutes). I have seen suggestions that the usb hardware can be a problem with USB1 devices and that an intervening hub fixes it, but I had not heard of a problem with a USB2 device.
I will report back for the record when I am convinced whether this is a complete solution. I will also document how to get owfs and openWRT running on the router, I presume that would be considered useful for inclusion in the wiki.
