Can I change the VID and PID of 5509 USB module? - Xiang Chao - Jan 18 9:52:05 2008



I can find any register to change the VID and PID. 
After USB bootload finished, my program will setup the
USB module and re-enumerate the USB device. But I want
to enumerate with new VID and PID.
thx

Chao Xiang

Why not? It's easy as you already know the registers. The only 
problem is confliction with other devices if you choose the ID 
randomly and it happens to be used by other devices.
