Re: Device enumeration fails



What kind of USB device? Is the driver included in the image? Are all the necessary registry settings on the device? What's the full debug output of the USB stack with all debug zones on? etc. etc. etc.

Without detailed info or a crystal ball it's very difficult for us to help you.


Good luck,

Hi,
I am having problems getting a certain full speed device to enumerate and get to the 'load driver' stage on Wince 5.0. The device is recognized and is usable when connected to my PC. I have used a USB sniffer to look at the packet traffic and it all seems reasonable. On the CE host, the device connection is detected and an attachment event is noticed in the HubStatusChangeThread in the host controller code. It calls ResetAndEnableHub port which returns OK, but when it tries to get a descriptor on the default control pipe, the process stalls. It is waiting for the callback for IssueTransfer and this never gets called.
I am not too familiar with this software or enumeration process... any suggestions on what can be done, or a where to look to find out more information?
