Issue 186: USB Audio Device Not working with Lion Chameleon

Reported by rockingturtle rockingturtle, Sep 28, 2011

Hey Guys,

I just finished setting up lion on my Acer 5745G and it seems to be 
working real well [main thread :]

For audio, the VHDA is working fine for me for output but I am 
getting a lot of static in the mic, I have tried fiddling with the 
prefpane settings but the noise doesn't go away.

I also have a USB HeadSet which I used when I was on 10.6.4 and it 
worked fine. But I am facing issues in getting it to work in Lion. 
Following are things I did and the results:

1) When I boot the system with USB Audio Dongle connected, its 
detected correctly and I am able to use it [so this implies its 
supported in Lion]
2) When I disconnect the dongle and reconnect it, it doesn't work, I 
installed the USB debug kexts from apple and attached the output [].
3) The dongle is working fine if I connect it to a 10.6 Snow leopard 
Virtual Machine running on Windows 7.
4) The dongle was working fine in 10.6.4, I have an external HDD on 
which I mirrored my 10.6.4 install before installing lion from 
scratch. I created the Lion install USB on the same hdd and upgraded 
the Chameleon Bootloader. Now when I boot it into 10.6.4 using this 
hdd, the dongle shows the same problem as in Lion.
5) All my USB devices are shown as inbuilt in System Information, I 
also have DSDT fixes for them, sleep works fine now.
6) I tried using USBBusFix but that doesn't help.
7) When I connect any other device to the same USB port, it 
functions properly.

KB      0x5ff7e000      4.1.15      16 KB      12 KB      

High level Error Message that I get:

  11.659 [1]	[0x80a0400] The IOUSBFamily was not able to enumerate a 

More detailed output in the attached file.

Any idea what might be wrong ?

My initial thought is that its something to do with chameleon as it 
was working fine earlier in 10.6.4. Stopped working in my cloned 
10.6.4 install when I upgraded the chameleon boot loader. Anyone 
aware of such an issue.

Thanks in advance.
