Ali, I am in the process of splitting this patch based on Kevin's recommendation. Planning to post it by this week but his recommendation was to post it in the linux-omap list and I might probably post it there. I think the same shall be available after the next resynch between the Omap and DaVinci Gits.

I'm using a custom board that only supports client mode, but USB gadgets work great using DMA with your patch. I used a ramdisk as the backing file for a File storage gadget, and I get 17.3MB/s average read speed on a WindowsXP host. Any chance this will be merged into the linux-davinci tree? _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
