Palm Background app and the system log Apps
I just realized that two lines of this kind are added every two seconds in my system.log (/var/log/system.log). They are shown on two lines each below to narrow the story width:
Jan 21 01:16:28 localhost mach_kernel: USB:  262.604: AppleUSBOHCI(0x188F000)::
ReturnOneTransaction - found the end of the transaction(0x97C73F0)!
Jan 21 01:16:28 localhost mach_kernel: USB: 262.604: -AppleUSBOHCI(0x188F000)::
ReturnOneTransaction - done, new queue head (L0x97C8180, P0x80F1E801) V0x1E8F180
It stops if I kill background palm application...

[Editor's note: Strangely enough, I do not have this entry in my log file on either machine that runs the Palm Background app. It's probably worth a quick look to see if yours is filling up quickly, though -- command-tilde then /var/log and check the size of system.log.]

Palm Transport Monitor the culprit
Authored by: Anonymous on Jan 22, '02 11:39:27AM

I'm experiencing the identical symptom. I killed Palm's Transport Monitor, and the excessive logging ceased.

I suspect you may not see this problem if HotSync is NOT enabled at system startup.

My fix...

Instead of killing processes, I was able to unplug and reinsert the USB adapter, which made the excessive logging stop.

I think that the USB-Serial adapter driver may be at fault. Also, I might believe that the versions have changed since the first release of the beta and subsequent releases announced at the macWorld Expo.

AppleUSBOHCI is an apple USB driver. You could, if you were feeling adventurous, go to the darwin CVS repository, check out the driver, and recompile it without the error/warning messages. It is pretty easy, I have done it with the iSub drivers. The relevant file with those log messages is Here. (get a free darwin account to log in) Anyway, this is truly a bug in palm's software, but you could send apple a bug on this (on the opensource bug site - - so they can come up with a way to disable such USBLog messages by the user. (perhaps there is) -B

Hmm, the site broke that URL on me. But not this one... Here. It seems GeekLog forcibly inserts a BR for every CR in your message. That's not what i would expect when i choose "HTML Formatted", i expect to be writing HTML. (e.g., I can hit return whereever I want, in this case in the middle of a URL, and it won't be messed up.) Most forums that I have seen don't do that, like slashdot.. Anyway, it would be a nice feature if the user was warned about it perhaps.

i didn't even know i had a problem.

this should be reported to palm by anyone who is experiencing it.

More info
Authored by: cyberassassin on Jan 23, '02 04:57:12PM

Upon unplugging and replugging the USB adapter, the system log will print this message:

Jan 23 16:43:localhost kextd[41]: loading module:

and no longer will continue to display the error message reported above, until another Sync with the handheld.

I think that the palm usb driver is doing a whole lot of unnecessary communication over the USB bus. Does anyone know of a way to do "packet captures" on the data bus. Might lead to more info...
