Just bought LP16.
Tried to update it from firmware 956 to 958. But every time i launch as admin the updater x64 the screen is “no supported device conncted”. Is there a way i can update the lp16 directly from the usb thumb dreive port?
How can i solve?
in addition, i cannot properly end the installation process for the usb interface. at hte end it keeps me telling installation failed. I rather pisse off because nothing seems to work just out of the box.

Thanx for the help
