Hello. I am writting from Huelva, Spain. My english is what you can read, sorry for that. I have a little trouble here



Sorry but i don't have exactly the error/notification message in english so i think it is better that i write it like it is showed.

I research it in the system, a little. The Device Manager (Administrador de dispositivos, in the capture) not show Ports now when i connect the GMC-390v2.



But in "controladoras de bus serie universal" appears the error



"Dispositivo USB desconocido (Error de solucitud de descriptor de dispositivo)" PLOP!

The drivers was installed:



The EF radiation detected is 150-160 V/m the whole time with AC and 77-78 V/m with battery.

If somebody knows how to fix a thing like that, any help in this line will be welcome.

Thanks in advance.
