[PATCH] usbhid: add ASUS LCM to the blacklist

[-- Attachment #1: Type: text/plain, Size: 469 bytes --]


Some of ASUS' notebooks (e.g G Series) include a tiny oled display, which is 
attached to an internal USB bus. Unfortunatly the device reports a wrong
DeviceDescriptor and is therefore identified as a HID device...

diff -p said that the second hnk goes into the hid_blacklist[] array, but
your patch actually places it in the hid_rdesc_blacklist[] array.

I suspect what we have here is a diff against 2.6.22?  Things changed
a lot since then - please prepare patches against the latest kernel you can get
your hands on, thanks.

Right! the last _two_ patches/resends were made from 2.6.22-*,
this time however, it's diffed from 2.6.23-rc1-git3... 
(I hope it get's merged before someone else has already changed
the line numbers again. ;) )

Hi Christian,

I have slightly modified your patch (let's keep the hid_blacklist[] 
properly sorted) and applied it into my tree.

Ok, found it " hid_blacklist is alphabetically sorted blacklist by quirk type. "
But is there a Order for the bitfields? e.g

shouldn't: hid-quriks.c (line 439, 440)

{ USB_VENDOR_ID_APPLE, USB_DEVICE_ID_APPLE_FOUNTAIN_ANSI, 
HID_QUIRK_POWERBOOK_HAS_FN | HID_QUIRK_IGNORE_MOUSE } 

be:
{..., ..., HID_QUIRK_IGNORE_MOUSE | HID_QUIRK_POWERBOOK_HAS_FN }


Anyway, thanks for merging! 
	Chr.

This could be a possible cleanup for hid_blacklist[], if you are going to 
make a patch I will happily accept it.

Cleaning up the USBHID's blacklist.

Ok! I'll make a patch..

But I have one (final?) question. Since I am sometimes stuck to 80x25 console...
 can we alphabetically sort the blacklist by the Vendor (the first field), instead of the quirk field(last field)?
Or is there a technical/theoretical reason behind it?   

Thanks,
	Chr.

I find the blacklist sorted by quirk type more convenient - we typically 
want to know "who has this particular quirk", but we generally don't care 
"what quirks does this particular vendor have".

Hi all,

I would like to comment on the topic quoted on
https://zockertown.de/s9y/archives/882-asusoled-compilieren.html  that
states something like this:


"I wrote a patch to correct this issue:
http://lkml.org/lkml/2007/7/23/530(get & try the patch) However, it
would be nice if it has "someone"
supporters! I've already wrote one for 2.6.22-gitX cycle... but it do not
get any feedback! please go
to:http://lkml.org/lkml/bounce/2007/7/23/530<https://zockertown.de/s9y/exit.php?url=aHR0cDovL2xrbWwub3JnL2xrbWwvYm91bmNlLzIwMDcvNy8yMy81MzA=&entry_id=882>send
it to your email address, write a feedback and use "answer all!".
That's it!"


Well I installed this patch, recompiled my kernel and tried again asusoled
application in order to test the oled display.
First time everything seemed as usual as it was with a standard (no patched)
kernel, asusolded ask me to rmmod  usbhid as it was not able to get control
on the oled.
Then I removed the usbhid and tried again, it worked. Nothing new.
After this I loaded usbhid in order to use my mouse.
then I tried asusoled  and  fortunately this time it worked  this time with
usbhid loaded.

To sum up the patch works fine once I remove and load usbhid once. I tend to
think this could be a bootstrap bug as it does work well after a manual
reload of usbhid.

I'll continue testing in order to see if it was just a spontaneous  problem.


My system:

Asus G1S
4GB
Open SuSE 10.3 X86_64
Kernel: 2.6.22.9-90 (Suse Build Service) patched with/to solve:
                                      4GB + BIOS + Nvidia problem
                                      oled recognized as usbhid device


PS.
I don't know  German so it was difficult to understand the page in
https://zockertown.de/s9y/archives/882-asusoled-compilieren.html so I would
suggest to update https://launchpad.net/asusoled/ maybe I could help.

Javier Bolaños Molina.

hmm, sounds like the old usbhid module is still around... 
My first guess: Do you use a initrd? Have you updated it, after you recompiled your kernel?

The project moved to sourceforge.net. The new maintainer is:

I think you are right, it's been so long since I compiled kernels by hand,
this time I used make rpm, I'll be looking for a new initrd as you suggest.
