PC finds unknown device if powered on after CY3014
HI I'm back because my customer feed me back a problem, since 2013 I finish the development of CY3014 and our usb3.0 products were sold well.
The problem is simple, if our device is powered on before the host PC, then PC powers on later and logs in the desktop, it finds a "unknown device" instead of 04b4,xxxx(sorry I can't remember the exact vid/pid of CY3014).
My driver will download my firmware to CY3014 if finding the 04b4,xxxx on usb bus, but this problem stop me doing the job and the device doesn't work.
Please help me，thanks
