usb broken in 2.4.0 test 12 versus 2.2.18

usb broken in 2.4.0 test 12 versus 2.2.18

[Heitzso]

I have a Canon usb camera that I access via a
recent copy of the s10sh program (with -u option).

Getting to the camera via s10sh -u worked through 
large sections of 2.4.0 test X but broke recently.  
I cannot say for certain which test/patch the 
break occurred in.

Running 2.4.0 test12 malloc errors appear.
Everything is fine with 2.2.18.  I haven't tried
the test13 series of patches.  

key .config options:
 CONFIG_USB on
 DEVICEFS on
 HOTPLUG on
 UHCI on
everything else off (i.e. printers, keyboards,
mice, etc.). 

Baseline system is RH6.2 with most patches applied
(so avoiding RH7 compiler problems).  Basic dev
environment is same (i.e. compiling the two kernels
on the same box).

If someone wants to email me a debug sequence or
ask more specific questions feel free.

Could you give us the exact error message you saw?

It works for me (s100), at least on my laptop. I do note that it gives
timeouts if the computer is busy otherwise.

gphoto2 isn't able to retrieve images using recent 2.4.0testX kernels, I
haven't tried earlier kernels yet. It is able to list filenames though.
