Dear Sarah / Greg, The Fresco xHCI host controller is able to recognize the USB 2.0 Mass Storage device when I attached to it. However, I have build a new custom kernel as explained by Sarah in her blog at the following link. http://sarah.thesharps.us/2009-06-09-13-30 It is build on version 2.6.32-rc5 kernel. I guess, the difference between 2.6.31.5 and 2.6.32-rc5 kernel images is "USB selective suspend/resume and wakeup". Means, while building the kernel images 2.6.31.5, I did NOT turn off it but while building the 2.6.32-rc5 kernel I turn off it. I have used the same .config file for both the kernels. Please suggest me, how can I turn off the above feature in the 2.6.31.5 kernel now. I am using the UBUNTU 9.04 distribution. On top it I build the 2.6.31.5 kernel and 2.6.32-rc4 kernel. The defult kernel version for that distribution is 2.6.28-11. Please usggest. Thanks for your help.
