10.5.6 + iRiver Music Manager = Kernel Panic

After upgrading to 10.5.6 (via the Combo Updater), when I run the iRiver Music Manager ( http://iriverinc.com/support/ultra/iFP-manager-mac.aspx) software running, and plug in my iRiver ifp-899 MP3 player via USB, I get an immediate kernel panic[*]. Very repeatable. I submitted a bug report ( http://developer.apple.com/bugreporter/bugrptform.html).

Anyone encounter this problem? Any workarounds? Anyone have experience using the open source IFP driver under OS X ( http://ifp-driver.sourceforge.net/)?

I get the same thing - iFP-795 & iFP-899 using OS-X 10.5.6 on a first generation MacBook, both crash as soon as Music manager is opened and the USB is connected. iRiver Music Manager works fine on my G4 Mac mini with 10.4.11 (which I'd considered upgrading to Leopard, but if I do, it seems I'll lose the use of my iRivers entirely).

Those little iRivers (the "podcaster's friend") are ideal for mobile recording - it's a shame that the current models don't have the same features. If iRiver are no longer supporting these on the latest operating systems they are - to put it mildly - misguided.

I understand that these solid-state devices can be switched to USB mass storage, but doing so will (for some unaccountable reason) sacrifice the ability to record at bit rates above 96k.

If iRiver wish to cede their market to the likes of Edirol (R.09), Marantz (PMD-660), Microtrack (24/96) and Zoom (H2 & H4), that's their (blinkered, IMHO) decision. I use a Microtrack and a Zoom H2, and I find them very effective, with none of this prohibition of mp3 copying. Of course these semi-pro recorders will also record in full CD quality as well as mp3, which is why I moved over to them.

I was also burned by this nasty problem! The UMS driver was not an option for me, because I care about the recording quality. Luckily I had to install VMWare Fusion and Windows on my MBP for other purposes, and I discovered that the Windows version of iRiver Music Manager works fine for me running on my Mac. Whew. I got VMWare+Windows (XP Home OEM edition) for $145 at newegg.com. Windows by itself is $90, for bootcampers. I don't know how that compares to MP3 players/recorders that would replace the iRiver.

Same thing here, ifp799 and any of the iriver musik managers I have - and I have 1.1.3 and 1.1.7, iMac after 10.5.6 update. Hope someone in Apple read forums and do something.

I have found a solution for this problem:

there is a linux program called ifp, which perfectly compiles and works on OS X, it is on sourceforge

http://ifp-driver.sourceforge.net/
and
http://libusb.wiki.sourceforge.net/

Compile libusb as usual:
./configure --prefix folder where_you_will_compileifp
make
make install
I did not install libusb systemwide. Copy all object files *.o to the folder where you will compile ifp.
generate CFLAGS and LDFLAGS with ./libusb-config --libs and ./libusb-config --cflags and substitute the corresponding expressions './libusb-config --libs' and './libusb-config --cflags' in the makefile.

There is no configure fore ifp, so just type
make
May make failed on linking, no matter how I put the FLAGS - it fails to see libraries. So I just said

cc -o ifp error.o descriptors.o usb.o darwin.o ifp.o ifp_routines.o unicodehack.o -Wl,-framework -Wl,IOKit -Wl,-framework -Wl,CoreFoundation -Wl,-prebind

where the cryptic part -Wl,-framework -Wl,IOKit -Wl,-framework -Wl,CoreFoundation -Wl,-prebind comes from
libusb-config --libs
and the files error.o descriptors.o usb.o darwin.o were copied from libusb folder.

man ./ifp.1
will show the instructions.

You can download my build (at your own risk) from anst.uu.se/angri367/ifp.gz

Here's the deal. 10.5.6 messed something up with USM.

http://blog.iphone-dev.org/page/2
under fixing dfu mode
It has the instructions for downgrading the USB drivers. basically get a free account on apples dev site
and then it gives the links to the sources of two dmg files

I downloaded and the music manager works like a charm.

Did you permanently reinstall 9F33 built 10.5.5 drivers? I understood, that the music manager works, but was there any noticeable negative effect on other peripherals like external HD, USB flash, etc. ?
