AJZaurusUSB Problem: kext doesn't load [SOLVED]

[Siddhartha V.]

Hi,

I've some problem using the AJZaurusUSB driver in order to connect my iPAQ under Familiar Linux (worked in the past). But I don't know where to start a topic.

Thanks for your help.

I've some problem using the AJZaurusUSB driver in order to connect my iPAQ under Familiar Linux (worked in the past). But I don't know where to start a topic.

Hi,
I have created a new subforum for the AJZaurusUSB driver.

My first questions are:
* which version of AJZaurusUSB are you using?
* which ersion of MacOS X?
* which iPAQ and Familiar distribution version?

Thanks a lot for the new subforum

I have installed AJZaurus USB 0.32 on my OS X.4.6 but I have this driver already installed but I don't remember which version (maybe 0.30 or 0.28).

I have an iPAQ 3970 running on Familiar Linux 0.84rc1.

To make a short long story, I fisrt installed the driver and failed to connect my iPAQ and my Mac. And on week ago, I tried again and I worked. In the in-between I have updated my iPAQ to the 0.84rc1.

But unfortunately, I wanted to connect again yesterday and the Network Pane in System Preferences never showed me the USB port up. But the iPAQ has his own usb configuration up and waiting.

I looked into the system logs and saw that the driver failed to initiate and stopped. I'm at work now, I'll post the entire log message about the driver output this evening when I'll be back home.

Unfortunately, I don't know what's the difference between this try and the last successful one. Maybe a system update but the last driver (0.32) is stamped "compiled under OS X.4.6".

P.S.: I had edited the Info.plist file in the AJZaurusUSB.kext in order to tha IOPersonality in order to match the idVendor and idManufacturer of my iPAQ.

[Siddhartha V.]

Sorry for the guest post and spelling mistakes (no edit button)

I sum up the tests :

Mac OS X.4.? - iPAQ 0.83dev - AJZaurusUSB 0.?? => fail

Mac OS X.4.? - iPAQ 0.84rc1 - AJZaurusUSB 0.?? => success

Mac OS X.4.6 - iPAQ 0.84rc1 - AJZaurusUSB 0.32 => fail

System log will follow. To be continued...

[hns]

P.S.: I had edited the Info.plist file in the AJZaurusUSB.kext in order to tha IOPersonality in order to match the idVendor and idManufacturer of my iPAQ.

Ah, that might be one reason. AJZaurusUSB installs a fresh Info.plist which is missing any changes.

The best thing is to report all new entries to us so that we can integrate them into the latest driver. I will make a note on the home page on this...

-- hns

[Siddhartha V.]

In fact, I just edited the file with Property List Editor and duplicated the iPAQ 38xx entry, only with changing the idProduct and idVendor and naming this entry iPAQ 3970.

I'll post the changes made to this file too, this evening.
Maybe if I make a fresh install of the 0.32 driver without changing the Info.plist, it could work. I'll give it a try.

[Siddhartha V.]

As promised, there is the system log messages when I turn my iPAQ on :

And as for the Info.plist adds :


I tried to install the driver again, in order to have a fresh driver, but after loading the kext and switching the iPAQ on, I have the same errors message on the log file.

[hns]

May 30 21:06:43 Omega kernel[0]: 0 0 AppleUSBCDCACMControl: start - configureACM failed
May 30 21:06:43 Omega kernel[0]: 0 0 AppleUSBCDCACMData: start - Find CDC driver failed

This appears to indicate that some Apple-provided driver is also trying to connect to the iPAQ.

Can you please verify the product&vendor id numbers through the system profiler? Since they are programmable in the Linux kernel, they even might have changed in your Linux distribution.

[hns]

Another idea: did you reboot the Mac after editing Info.plist?

[Siddhartha V.]

I've uninstalled the driver and rebooted. After that, when I turn on the iPAQ I have only this message in the system log :

Code: Select all

Jun  2 09:08:57 Omega kernel[0]: 0        0 AppleUSBCDC: start - initDevice failed


And here is the IORegisteryExplorer result for my iPAQ :


I'll now try to install the driver again, reboot and switch on once more in order to see if something changes.

Stay tuned

[Siddhartha V.]

After a fresh install + reboot, I've this :

The last line seems to be an alternative try of the kernel to deal with the peripheral after the failure of the first driver.

I'm going to try now after editing the Info.plist

[Siddhartha V.]

And last report. I've edited Info.plist + rebooted and have had the same error on system log.

I've tried to force a kextcache rebuild by deleting /System/Library/Extensions.* (according to this post in an Apple Mailing-List).
After the system reboot, I see the same problem as pointed out first :

An AppleUSBCDCACMControl appears in the middle of the init.

Any idea of what occurs ?
Or any other test I can drive to help you ?

As I use to say : "Wait & See"

[hns]

I have now (finally) tried an Acer n30 with Familiar&GPE - and I get the same error messages.

Only a small deviation in the number of interfaces in Config: 1

And even the "AppleUSBCDCACMControl: start - configureACM failed" appears at the same position!

Since also the vendor id and product id are the same (and not the original one from Acer), I assume that the latest Familiar kernel has a somehow different setup.

So, the answer to the question "what has changed?" is the Linux on the PDA...

This will need further study how the Familiar IP over USB system is different from the Zaurus. And some coding and testing to fix it.

So, I do not yet have a solution.

[Siddhartha V.]

I've posted a question on the mailing-list about possible changes in the driver on the PDA.

I'm waiting for an answer and/or the final 0.84 release.

[Siddhartha V.]

According to a mail in the mailing-list, the g_ether driver claims to be a RNIS device instead of the usb-eth tat claims to be a CDC device.

Maybe, I'll have a iPaq functional again by unactivating the g_ether driver and re-activate the usb-eth.

I'll post the results of my experience ASAP.
