<br>
</span>Thanks for the suggestion, Alan. I will be adding this to my proposal.<br>
Also, which BSP would you recommend that I pick up ? Is there any list<br>
of currently added BSPs from which I can choose?<br>

><br>
</span>I was also thinking for that. I have a Raspberry PI 1/B+ and a<br>
majority of users have either 1/B+ or 2/B. Probably we can start with<br>
1/B+ and then enable the other models.<br>

<br>
</span>Sure, I had left some buffer time in my proposal, probably if things<br>
goes as per plan that time can be used for USB support for the<br>
BCM2835.<br>
