Default PC don't recognize Galaxy Tab 3 8.0 in download mode

First of all

I have to two devices, Galaxy S 4 and Galaxy Tab 3 8.0 and my laptop is running Windows 8.1 with all Samsung drivers, Kies , Odin 3.09

Secondly : I usually update my Galaxy S 4 using Odin without problems but when i tried to update my Galaxy Tab 3 8.0, PC recognize the device when it's turned on and recovery mode, but do not recognize it when i enter Download mode. What to do ?

Tried : Using the original USB, Changing the USB, USING S 4 USB (which is working with s 4 in download mode) , RE-installing Samsung drivers and finally changing Odin's version

Result : Problems not solved

Galaxy Tab 3 8.0 model : SM-T310
