Hi Paco,

yes, usb was totaly dad, no 5V on the bus, and the V33 Pin on the GL850 was connected to GND.

But good news, today the delivery from china arrived with 5 GL850G included. The replacement was not easy, but it could be done (i have cutted the pins with a sharp nife to remove the chip, the cleaned the pads)
Now usb devices are visible and also booting is possible now!

 Thank you very much, you showed me the right way! If you send me your postal address, i will send you a chip by mail!

thanks

Hi,

at the moment, i dont like to buy another guruplug with the same failor, in addition i don't know if i shoud buy a guruplug again.

But i will try to replace the GL850 when my delivery from China will arrive. I found a supplier at aliexpress that delivers 5 pices for 8$ inc. shipping to germany. If you like i could send you one of it by mail (the non-e one ;-)?

Hi PacoLM,
