G15 on Linux

G'day,

Posted a patch on SourceForge last week adding media keys support to the G510.

enjoy,
multitude

ps. Posted a notification here at the same time but it's disappeared in to moderatorland.

G'day all,

This is another attempt to get my G510 support patch posted without it being queued for moderation...

As mentioned in my earlier post, this patch provides custom LED colours (read color for US) and preliminary key support.

Unfortunately media keys are disabled at this time. There is a current limitation in the 'g15tools' implementation which prevents their use (as well as full G13 support). Also of note, the site's autoformatting is removing leading spaces in the patches.

After applying the patches, you may modify the following line in 'libg15.c' to taste:

setG510LEDColor(0, 255, 0);

enjoy,
multitude

For those experimenting with your G510 and having to physically disconnect and reconnect your keyboard all the time, you can restart your 'usbhid' module instead. Create a bash script with the contents below and have it within easy clicking distance:

#!/bash/bin
modprobe -r usbhid
modprobe usbhid

Of note, this will also restart any other 'usbhid' devices you have connected and you may need superuser privileges.

Have fun,
multitude

More information :
I have added
DEVICE("Logitech G510",0x46d,0xc22d,G15_LCD|G15_KEYS|G15_DEVICE_5BYTE_RETURN|G15_DEVICE_IS_SHARED),

and
printf("Return : %d\n",ret);
printf("Data : %2X %2X %2X %2X %2X %2X\n",buffer[0],buffer[1],buffer[2],buffer[3],buffer[4]);

just after usb_interrupt_read.

And i got that :

libg15: Done opening the keyboard
g15daemon 1.2svn loaded

The C7 is alwais here, the following value are random.
When i press a key, it goes with 1,0,7,0,0 and with 1,0,0,0,0 when i release it
the 7 depent on the key pressed. For "s" it return 16.

As long as i keep the key pressed, i got this code and it work only once. after i need to close g15daemon, remove et plug the keyboard

But on the other side the LCD work fine with g15cat

I have the same keyboard and the same issue.

my keyboard is the Logitech G510, ID 046d:c22d Logitech, Inc.

With svn g15daemon, no keyboard but lcd.
It appear that first "Extra Keys" detected are the whole keyboard+lcd key+G key+M key
The second Extra Keys are the right side of keyboard : media touch (pause,stop,rewind,forward,mute,volume) and keyboard light on/off

I'm running ubuntu too, but kde.

Without g15daemon, the "normal" keyboard work fine, media touch also.

And i'm also non-english.
