Hello , i have a brand new interface ( 1-2 months old ) Hex V2 . It suddenly shows Interface not found , in the middle of whatever im doing is very frustrating i can't code anything because it scares me . I used it to clear faults and watch some live data only till now because of this intermitent error . Im begging for some help . I will provide anything you guys ask me . Some info ... : I use an acer p531h-0bk with Windows 7 ultimate x32 . I used latest version 18.2.1 , interface is updated to latest fw too . After it shows me interface not found , if i unplug and plug again it will blink green 1 time and then leds go off . When it works it blink 1 time green then blue . Now strange things start here .. it won't work untill i reboot the laptop , if i reboot , it will work again ( for a while till will randomly " interface not found " ) . I tried another laptop with windows 10 this time and plugged into a usb3.0 port ... this time when VCDS said interface not found ...windows 10 also said " Power Surge , an usb deviced is asking for more power " . PS. I am located in Romania , the interface is bought from ASPAD Com S.R.L. which is a certified seller . Thank you very much for your time and sorry for my english !
