Hello
Yes I did apply mh patches. I can put a copy of the kernel online if
you want to see it.
I'm not sure I understand the "report mode". Pressing on a keyboard
key after hidd --connect make the key work in applications. It's not
simply reporting.
hidp_keycode is declared locally in core.c and never used elsewhere.
input_report_key seems to send hidp_keycode[keys[i]] to the input
layer. If I printk this, I only see 0.=20
What I want to do on my strange keyboard is :
swap tab and capslock
swap capslock and esc
So I swapped 15 and 58, then 58 and 1 in the hidp_keycodes, but this
only gets me multiple esc. However, replacing keycodes 65 and 66 by 0
which where incorrectly send when pressing on a special keyboard
modifier key worked, as did swapping keycode 30 and 125 (some library
has keycode 30=3Dmodfier hardcoded in, so I had to do a workaround and
remap the a key to 125 and change the keyboard map accordingly)
This suggest that my approach should work. I don't understand why it's
not working with tab/capslock/esc.
I'm puzzled. Any suggestion is welcome.

a HID device can work in two modes, boot mode and report mode. The boot
mode is a limited mode with a predefined descriptor and thus it needs a
keycode mapping table. In report mode the HID parser decodes the HID
report according to his descriptor and then generates the keycode. In
the latter case the hidp_keycodes[] table is not used, but it is a boot
mode only thing.

To make this working in report mode, you must replace the HID descriptor
or tell hidd to use the boot mode only. Speaking of which, I just saw
that I never added support for pushing a device into boot mode. However
the --nosdp option should do the trick.

It doesn't. Here's the table I'm using in
kernel/net/bluetooth/hidp/core.c :
static unsigned char hidp_keycode[256] =3D {
0, 0, 0, 0, 125, 48, 46, 32, 18, 33, 34, 35, 23, 36, 37, 38,
50, 49, 24, 25, 16, 19, 31, 20, 22, 47, 17, 45, 21, 44, 2, 3,
4, 5, 6, 7, 8, 9, 10, 11, 28, 58, 14, 1, 57, 12, 13, 26,
27, 43, 43, 39, 40, 41, 51, 52, 53, 15, 59, 60, 61, 62, 63, 64,
0, 0, 67, 68, 87, 67, 99, 70,119,110,102,104,111,107,109,106,
105,108,103, 69, 98, 55, 74, 78, 96, 79, 80, 81, 75, 76, 77, 71,
72, 73, 82, 83, 86,127,116,117,183,184,185,186,187,188,189,190,
191,192,193,194,134,138,130,132,128,129,131,137,133,135,136,113,
115,114, 0, 0, 0,121, 0, 89, 93,124, 92, 94, 95, 0, 0, 0,
122,123, 90, 91, 85, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
29, 42, 56, 30, 97, 54,100,126,164,166,165,163,161,115,114,113,
150,158,159,128,136,177,178,176,142,152,173,140
};
As you can see, 30/125 1/15/58 have been swapped, and 65/66 have been rem=
oved. (that's necessary).
Yet it doesn't work. I still even get 65 and 66. I'm using bluez 2.16 (ex=
cept sdptool - cf other message) with
the kernel patch. The kernel is on
http://externe.net/zaurus/kernel/sources/linux-2.4.18-rmk7-pxa3-20050501.=
tar.gz
I first though my ifdef were at fault. I removed everything- I only have =
this hidp_keycode now. Still doesn't work anyway.
Would you have a patch for hidd or a suggestion?
