Hi My name is Divyang Mali & I am working in one of the semiconductor company in Bangluru(India).
We are developing USB 3.0 device IP. But, we stuck in issue regarding to Enumeration of USB 3.0 in Windows.
As we debug this issue we found that Enumeration is not progress after DEVICE DESCRIPTOR request with NEC Host Controller. In Device Manger it shows unknown device. As we go for device properties, under General tab device status is "The device can not start. (Code 10). Unable to access the registry". And also under Events tab information is "Device USB\VID_PID.... has a problem starting with (null)".
And, our device is a custom class device.
So, please can anybody help me on this or provide some information on this.
