Hi All, I'm working on kernel 2.6.30 installed on a pxa320 based board. I want to insert a USB driver to test its working. It inserts well in 2.6.25, and also creates /dev/sd(a/b) devices with the help of udev; but in 2.6.30, it comes to a point and stalls. I'm attaching the log of what happens when it is inserted in 2.6.30.
