If this firmware file is missing renesas_usb_fw.mem  
I have an issue with a PCIE to USB 3.0 card ( Renesas Technology Corp. 
uPD720201 ) which stops working at 22 hourts after boot withtout this firmware 
file. 
If I manually add it to /lib/firmaware/renesas_usb_fw.mem and load the firmware 
by reinitializing the PCIE card it works.
It is best if the firmware file is there and is loadded after boot.

Please, fix it....
