Dear Harsha, The host and device do support each other. Both are dongles based on the WISAIR 601 chipset. The CBAF process is successful (I can see the CHID and CDID programmed correctly to the device NVRAM. Both dongles are working on the same channel and I can see the beacons, MMCs and the DN_CONNECT commands in the air trace captured with a WUSB explorer. After the DN_CONNECT message from the device to the host, the hwa driver on the host crashes with the log I provided. The host system is based on Ubuntu running kernel version 2.6.28.2. Many thanks, Eyal ________________________________________ From: Harsha [mailto:harsha.081979@xxxxxxxxx] Sent: Monday, March 02, 2009 12:16 PM To: Eyal Reizer Cc: david.vrabel@xxxxxxx; linux-usb@xxxxxxxxxxxxxxx Subject: Re: WUSB driver crash after DN_CONNECT message from WUSB device Dear Eyal, CBAF comes into picture only when both Host and Device possess mutual support for each other. Please do verify the initial config settings such as CHID, Bandwidth Channel number, Cluster ID etc ...... May I know the linux version / type being used in the setup ? Thanks, Harsha 2009/3/2 eyal reizer eyalr@xxxxxxxxxx Dear David, I have a set of a host and device which I have paired using the cable association service and now the device tries to connect wirelessly. As soon as the DN_CONNECT from the device is received by the host bad things start happening until finally a crash is caused. Have you seen this type of problem below? any hints on what is going wrong?
