Maybe I read the kernel OOPS wrong. Was &ep->desc NULL or not?
It's hard to tell from the information in the oops. You'd have to get
an assembly listing of usb_submit_urb() and figure out what source code
statement corresponds to offset 0x75 in the object code.
Why did you originally think the problem was in the usb_endpoint_type
function call?
I used gdb, I compile my own kernels so that was not hard. I just had
to recompile that file with debug symbols (-g).
It said the problems is in the usb_endpoint_type(const struct
usb_endpoint_descriptor *epd)
inline function that only does epd->bmAttributes
Also when I added the check for a NULL &ep->desc just before the call
to usb_endpoint_type I no longer got an OOPS, so that confirmed to me
that &ep->desc is NULL
Maybe I can log the ep pointer, and something else in that case?
ps.
I'm not so experienced with C so I might mixed stuff up.
