Re: [M560x-driver-support] What do the developers use for development?

[Ivan V. <iv...@gm...>]

Thanks for the response!

Here are some of the notes from my experiences with that branch. I'm sorry 
for being ignorant on how to produce patches that might be easier for 
you to use.

1) Kernel 2.6.22 no longer includes file linux/usb_ch9.h, now it's called 
linux/usb/ch9.h.
I changed the include appropriately.
2) Changed the device definitions as here:
////////CUT
static struct usb_device_id m5603c_table[] = {
         {USB_DEVICE(0x0458, 0x7020)},
     {USB_DEVICE(0x041e, 0x4038)},
     {USB_DEVICE(0x0402, 0x5603)},
     {}
};

static char* m5603c_name[4] = {
     "Genius Slim 321C",
     "Creative WebCam Live! Pro",
     "Sweex",
     NULL
};
/////////CUT

I did not study the code below, but is the name in the m5603c_name array 
supposed to match whatever the device reports? (Currently, lsusb seems to 
be playing tricks on me, and /proc/bus/usb/devices seems to report name of 
"For demo only", which seems right to me since I saw that somewhere, too, 
but not in the lsusb listing).

3) Test program for sweex 5603 needs modification in pusb-linux.h. At 
beginning add:
///// CUT
#define BITS_PER_LONG 32
#include <linux/types.h>
///// CUT
Looks like they added an #ifdef __KERNEL__, that's why this is needed.
4) Same test program, pusb-linux.c in line 285 change ctrl.bRequesttype 
into ctrl.bRequestType. In Makefile, in line 8, remove -DFC5.

Images that were generated seem to have only 0x0a0a0a color. When I ran it 
later on, it appears to have frozen somewhere.

5) Driver only generates blank picture, too.
6) $ insmod m5603c DBUG=16
m5603c: Unknown parameter `DBUG'

I also tried with DBG and DEBUG.

7) I did experience some null pointer related errors, but they appear to 
be gone now. (I don't know what I did, I'll inform you if they 
resurface.)


Hopefully some of this helps!
