Author Topic: DIR-825 stays on without power cord when powered USB hub is connected  (Read 6047 times)

The topic says it all;
My DIR-825 stays on even when I flick the power switch, for as long as I don't disconnect the externally powered Belkin USB hub from it. Some lights do come off, Internet light turns orange, but it stays on. If I disconnect the hub before trying to shut down the router, it turns off instantly.

I feel slightly worried by this because as far as I am aware, a USB client device shouldn't be feeding power to the host. On the other hand, the host shouldn't be accepting power from the client either.

Also, sometimes after days since last reboot, the USB light on the router is not on despite connected devices, and they may or may not appear in Shareport.

Should I just have both the router and the hub serviced, or has anyone had similar experiences?

The USB hub is providing power as well. I don't think connecting a hub would be supported as only one device connected is recommended at a time.

Are you sure it's not supported? I've successfully shared up to 5 devices via Shareport at the same time.

Moreover, isn't a USB client feeding current into the port that connects to the host device quite out of specification?

Ya you've got a USB device or client feeding back into the Port on the router.
