Fwd: Tr: Boot time Bluetooth BUG: warning: (value > m) at hid-core.c:793

[Veronique & Vincent <vinctre@videotron.ca>]

Hi Jiri,

Here is the code I've changed into the hid-core.c into my 2.6.19.3 kernel:
#include <linux/input.h>
#include <linux/wait.h>

/*
#undef DEBUG
#undef DEBUG_DATA
*/
#define DEBUG
#define DEBUG_DATA

#include <linux/usb.h>


I've attached a few dmesg... They where all taken during the same boot.. I 
just tought I'd overpass the maximum buffer output...

I have booted the PC with the USB dongle already plugged in... The PC booted 
and showed a BUG when bluetooth service fired up... Once the login prompt 
appeared (with a lot of debug msgs) both the bluetooth mouse and keyboard 
refused to work.. (has usual... so this time I had also plugged in a PS2 
keyboard and mouse)  So I disconnected the dongle and the debug msgs stopped 
right away... Then I replugged in the dongle and played a bit (really just a 
bit) with the keyboard and mouse (they did worked)... Then I disconected 
again the dongle to see something else then only debug msgs...

There are a few input/hid-core.c: report descriptor  messages:
dmesg1:drivers/usb/input/hid-core.c: HID probe called for ifnum 0

I extracted them using a simple grep from all the dmesg output I have.

Hope this helps...

Unless

Unfortunately it was missing the report descriptor dump. The output should 
look like

drivers/usb/input/hid-core.c: report descriptor (size 59, read 59) = 05 01 
09 06 a1 01 05 07 19 e0 29 e7 15 00 25 01 75 01 95 08 81 02 81 03 95 05 05

00 2a a4 00 81 00 c0

and it should appear as soon as you connect the device. If it didn't, I 
suspect that the 

	#define DEBUG_DATA

was not set properly in drivers/usb/input/hid-core.c (only defining DEBUG 
is not enough for report descriptor dump to appear).

But so far all reports that have gathered for this bug at me seem to come 
from FC6 ... does hid2hci by any chance in FC6 have any additional patches 
that could be causing it, instead of being a kernel issue?
