Weird system.log messages

musiker01 · Post by **musiker01** » Sat Dec 27, 2008 4:59 pm

Hi experts,

I have a problem with my midi. Sometimes it takes Live very long to react to the control messages from my fcb1010. Also, with some messages, I have to push a button twice in order for it to react. The messages do come in though as MidiPipe shows. Now I've checked my system.log and found that while Live is running, these error messages show up. The second one repeats about three times per second.

Code: Select all

Dec 27 17:43:53 alexanders-computer kernel[0]: Error: E00002EB 38 0 2eb (/Users/hitesh/Drivers/OsXMidiDriver/USBKext/IsocInHandler.cpp, 131)
Dec 27 17:43:53 alexanders-computer kernel[0]: Error: E0004007 38 1 7 (/Users/hitesh/Drivers/OsXMidiDriver/USBKext/IsocInHandler.cpp, 131)

Does anybody know what this could mean? There definitely isn't a User 'hitesh'. Unfortunately, I've been doing lots of stuff with computer lately, including installing plugins and hacking away with MidiPipe, Supercollider and Augustus Loops midi scripts.

My setup: MBP 2.1 Core2Duo, Line 6 UX2, Motu Fastlane, Trigger Finger, FCB1010, OS X 10.4.11

Thanks,
Axl

hi musiker01,

hitesh isn`t a user,it`s a directory.

Dec 27 17:43:53 alexanders-computer kernel[0]: Error: E00002EB 38 0 2eb (/Users/hitesh/Drivers/OsXMidiDriver/USBKext/IsocInHandler.cpp, 131)

this is a path to a usb kernel extension.IsocInHandler.cpp, 131 is c++ code,
it seems that you have a compiler error.maybe a peace of broken code or a corrupt
.cpp file

Seems to me that as a first step I should try to locate this IsocInHandler thingy. Unfortunately I can't find it (via Terminal and Spotlight) and as I said there is no directory called hitesh.

I just found that the same thing happens when I load Tracktion. Can anybody tell me how I should proceed? I have to make some music.

sorry for this question,but i find out that logic users have the same prob.
it seems that is a memory addressing prob.maybe from os x in conjunction with intel processors.did you see any malloc errors?

other people have probs with midi hardware,and the same failure.
on my old g4 i dont have this trouble.

It get's weirder. I have found the errors are associated with my Motu Fastlane interface. It is connected to a Logitech 4 port hub which never has been a real problem. I recently connected the powersupply to the hub because I figured having two bus powered devices (Fastlane and Trigger Finger) on the hub this would get rid of some stuck notes I was experiencing when playing the synth. I reinstalled the Motu driver but this didn't change anything. But when I plug the Interface directly into the computers USB port, the errors are gone, except when I quit the application using it they show up four times.

At this point, I don't expect anyone here to be able to help me anymore. Having done audio on computer for about 10 years now, I think of myself as a pretty experienced user. But each new problem seems like a total mistery to me. And they never repeat. Seems like there is a truly endless possibility of errors to be encountered. Does anyone feel the same.

I've contacted Motu tech support. Maybe they have seen the error messages before.

Thanks for participating, am.
