hi all,

 

      I bought a new i.MX535 qsb board yestreday, in that the usb is not detecting in my uImage, but i have one more QSB board before, i was testing all the pheripherals in that board with the same uImage. Both are same boards. When i used to boot the new board from the freescale SD card the usb is detecting, is there any change in the new kernel, if it so can any one guide me where the change is

 

KERNEL VERSION which i am using is

 

Linux kernel version: 2.6.35.3
