After a few weeks of testing I have hopefully narrowed down the problems with my latest WR703N setup, where it continues to reset the internal USB hub. I have plugged in an additional USB hub (un-powered) and plugged the USB flash drive and GPS into that. The GPS works straight away and the USB flash drive (/dev/sda2) doesnt have the same I/O and filesystem errors. Will perform thorough testing through out the next week and see how is goes.
In the previous post I thought it was power to the internal hub, so I have tried adding a 100uF capacitor. It initially started out being a r/w lock on the Sandisk USB flash drive, which I think was a result of a poorly constructed USB hub.
UPDATE 16-9-12
Found a USB hub that can be powered via an extra USB power lead and like usual results look good but time will tell.

Curious for an update on how things are working here. I am having similar issues with external hubs. I don’t have the external power packs for either of the hubs I am tinkering with. I may end up breaking out the soldering iron and hard wiring the power, but I would like for it all to be stable before I resort to that. Catch-22. lol
Hi Eug, My current stable setup for power/USB is a double ended USB cable going to another double end. This powers the board and a USB hub. Its made from a few different cables. This way you only need 1 power cable to power both the board and HUB. I use a ‘2amp’ USB car charger for a power supply. I have the hub running a flash drive and GPS, flawlessly off the powered USB hub. I think this would also be good for you because you can just cut and solder some cables.
Cheers
Come to think of it, I don’t have the lot plugged into the best power source. I have the WR703 getting it’s power from a powered hub on my desktop and not from a USB wall wart. Your X cable sounds like a good solution for testing.
Thanks!
Yeah I’d start with more than enough amps and work down, I have had 2 running off external phone batteries using an X cable mentioned and the USB devices have behaved pretty well (USB sound card excluded).
Cheers.
Hi sorry, but so what is the best way to install a hub usb..??
Thanks a lot..
Hi Matteo, The best usb hubs to use are ones that are powered by 5v adapters, that way you can use the same power supply. I have found that most smaller USB thumb drives just aren’t reliable and tend to be intermittant, where the larger ones will work very well on un-powered hubs.
Cheers
