[Q] N7000 not recognized by windows.

Hello all,
My mother has a GT-N7000 running complete stock.
It updated something according to ehr saying and afterwards it rebooted.
After the reboot it rebooted again and now its bootlooping, it shows samsung and plays the sound.
The bleu glaze comes up and the the device reboots.
I cant get into recovery with vol up+home+power button combo.
It boots to it and it shows the droid with the sort of cubic icon spinning in its belly and after 3 sec the device reboots.
I cant do a factory reset there so i read about Odin and reflash stock image.
I downloaded the proper file and Odin 3.0.9 and installed samsung drivers.
I dont have Kies installed as i read it could give problems.
The device does go i ndownlaod mode but my PC running w7 ultimate 64bit doesnt recognize the device.
I tried 3 different USB ports from the Mobo, and i tried a couple of diferent USB cables.
One of the cables is original Samung U2 cable.
Everyt time i connect the device winodws shows the message: the USB device isnt recognized.
Odin doesnt register anything so i cant flash a thing with it to restore.
Does this mean the device is bricked?
Does the N7000 has some sort of unbrick JTAG mode or something or would linux help to rewrite all partitions?
Thx for any tips.
With best ergards,
Mister_mini
Edit: thinking back it could be possible USB debuuging has been turned on but im not sure on this part.

Unable to open "USB computer connection" or connect via USB

I have the d415 and I have been running the latest version of the UberSlimOS ROM, for two months without any major problems. The only problem I do have is that I am unable to connect the phone to the computer. When I plug it in, nothing shows up on the computer or the phone (I have tried this under both Windows 10 and Ubuntu 14.03 & 15.10). I have installed and uninstalled the LG drivers on Windows. I have tried installing another rom (OrionLP) with a clean wipe. Neither of these work. The phone shows up when I plug it in when it is booted in recovery mode, but in regular phone mode I get nothing.
What should I do

Trying to flash via EDL mode but the phone keeps on disappearing in Device Manager

so I can connect my bricked phone to a Windows PC by shorting the test points. But the device (Qualcomm HS-USB QLoader xxx) also keeps on disappearing in Device Manager. In most cases, the device only shows up in Device Manager for 1 second and disappears immediately.
Any ideas on how to fix?
Thanks
