i hated that chip. I got this work though. for what it is worth.

Hi,

I have the following;
03:00.0 USB controller: Renesas Technology Corp. uPD720201 USB 3.0 Host Controller (rev 03)

When I run setpci -s 03:00.0 fw.6, I get 8000 as expected. However, when I run setpci -s 03:00.0 ec.1 I get the following error message.

setpci: Invalid width “1″.

My knowledge about eeprom etc is zilch so would appreciate if you can shed some light on what is going on with my card.

Many thanks
