Hi,
I was trying to compile and load the usb-skeleton.c
present in the drivers source. It compiled fine (after
making the reqd changes in version.h and irq.h). but,
when loading it gave the following oops. I googled for
a possible solution but came up with none. Anyone
faced a similar situation. What am i missing here.
