Wallstreet II / PDQ trackpad won't notap using pbbuttons

[Tommy T. <tom...@gm...>]

[Duplicate message; my apologies if this has come through more than once.]

I've been trying to track down a couple of problems I have had for
months after upgrading to Ubuntu Breezy. One has to do with the
trackpad intitializing at tap, drag, lock -- I opened Bug #25942 in
launchpad https://launchpad.net/distros/ubuntu/+source/pbbuttonsd/+bug/2594=
2

I only recently realized pbbcmd is not able to set the state of the
trackpad. When I use pbbcmd, it is setting a register, but NOT
changing the state of the trackpad:

$ pbbcmd config tpmode 1
$ pbbcmd query tpmode
1
$ pbbcmd config tpmode 0
$ sudo trackpad show
READREG(3, 2) trackpad settings tap drag lock
$ sudo trackpad notap
$ sudo trackpad show
READREG(3, 2) trackpad settings notap nodrag nolock

I just discovered the news at
http://pbbuttons.berlios.de/newsarchive.html and noticed that some ADB
code changed between 0.6.x and 0.7.0 -- maybe a change in that code
affected my hardware, because it was working fine in Hoary (pbbuttonsd
0.6.6-3ubuntu3). I have tried installing the latest binary in Dapper
(0.7.2-1ubuntu4) but so far its behavior is the same.

I am not experienced in C programming so I have had trouble finding
the place(s) in the source code that point to the adb... I'd be happy
to try some diagnostics and even compile a patched version if someone
can give me some assistance.

I'm running the binary from Dapper but the package didn't install
fully because I'm still running an older version of libasound2 -- and
I am assuming that's not relevant to this issue.

Here are some things I have looked at...

$ pbbcmd query version
0.7.2
$ pbbcmd query sysinfo

$ pbbcmd query identity

It seems that you suffer from an inaccurate machine check.
Pbbuttonsd have to check now if you machine has a ADB trackpad or not,
because the last ppc PowerPooks have a USB trackpad and had problems
talking to an not existing bus.

Could you please provide the contents of /proc/cpuinfo to prove this
theory?

 Best Regards
