Unabled to connect to my D800 with TL-MR3040

[Amaury]

Hello,
Thank for your software, it's very fun to use.
I'am trying to use it via wifi, so i buy a TL-MR3040. I follow the differents step to flsah firmware with the last version fond on dslrdashboard.info.

When i log to the TL-MR3040, i have the good version of ddserver and it's running.
When i connect my D800 with USB 3 cable on the TL-MR3040, nothing happen.
If i have a look to system.log on the TL-MR3040, i saw that it detect a new high usb device and it says that device not acceot adress xx error -71.

I try with to différent cable and i try to reset the TL-MR3040 and re-flash it in its standar factory and then flash it again with your openWRT firmware, but always the same result. If i look around in menu of TL-MR3040 i saw that it recognise my camera.
I try with a D810 and it's the same way.

Have you an idea ?

Flash factory first

DDServer OpenWrt MR3040 V2 Factory 0.13

Then flash Sysupgrade file

DDServer OpenWrt MR3040 V2 Sysupgrade 0.13
