[SOLVED] New kernel driver for the BCM5974 touchpad (Macbook Air, Penryn)

[kosumi68]

Hi kimtiede,

I am glad it worked out, but it troubles me that your setup was not automatically detected. It would be most helpful if you could provide the output of these commands:

which lsusb
lsusb

It would make it possible for me to test the installation further. Cheers!

Hi Cyberdork,

thanks - it will indeed be a lot easier!

[kosumi68]

Welcome back alex,

Hi Henrik,
An easier way would be to just use one quirks line for both Air and Penryn [..]
Since there is no clash for the device ids, the hid module will use the corresponding quirk for the given hardware. That way you won't have to do any sort of hardware detection during installation.

*blushes* Here is one that thought there was a limit of four set in the kernel... I guess it applies to a single id, not the total?

First, I want to echo everyone else here in saying: thank you.

I just tried to install version 0.53 from the .deb on my MBP, on Ubuntu 8.04 (fully updated, kernel 2.6.24-19-generic). Installation appeared to fail on the post install script. Unfortunately, the trackpad works exactly as it did before installing the driver.

The installer runs fine until the post installer script where it complains that it cant find kernel -17, or -18, and then appears to give up without trying -19.

I've been looking over the forum, and I've tried to provide for you the information you've asked for in the past for debugging purposes. If there is any other information I can provide for you, or testing I can do, I'm more than happy to help.

First off,

/etc/modprobe/d/bcm5974

quirks had the penryn commented out, instead of the Macbook Air (assumedly because the post install scrip failed). However, changing the comments and reloading the driver using

sudo rmmod bcm5974; sudo modprobe bcm5974

a) did not freeze my trackpad and b) did not solve the problem.

Here is the output from diagnostics:

* Kernel version: 2.6.24-19-generic
* Synaptics version: 0.14.7~git20070706-1ubuntu4
* USB device: Bus 007 Device 003: ID 05ac:0230 Apple Computer, Inc.

*blushes* Here is one that thought there was a limit of four set in the kernel... I guess it applies to a single id, not the total?

Actually I did not realize that MAX_USBHID_BOOT_QUIRKS was set to 4. I think you're right the maximum is four quirks. Bummer, I guess I can't think of an easier way than what you're already doing.

Detection of the hardware failed on my macbook pro running hardy 64bit. Here's the output of "which lsusb":

/usr/sbin/lsusb

and "lsusb":

Good news: the post-install script was so full of bugs i must have been asleep when writing it.

bcm5974-0.54 released:

* Penryn trackpad dimensions fine-tuned

* x86_64 for 2.6.24-19-generic

* post-install fixed

Enjoy!

[kosumi68]

sbayless, thanks for the extensive report!

Yes, the post-install problem is consistent, should work in 0.54.

Did you reboot your machine after installing? At least it is consistent with the problem.

[sbayless]

Did you reboot your machine after installing?

Yes, I did reboot the machine after installing.

I can confirm that 0.54 fixes the hardware misdetection issue

I am relieved!
