BrcmPatchRAM - Upload firmware into Broadcom Bluetooth USB devices

[zev23]

Some sort of USB problem. You can see that BrcmPatchRAM2 is hanging, no doubt due to failure during firmware upload.

I notice some unusual USB software:
- Virtualbox
- com.eltima.kext.eveusb

Also, I notice the device is connected to a USB1 controller (AppleUSBUHCIPCI). Really old hardware here?

Yes quite old, C2Q ICH10 hardware.

The USB ports on the board are all USB2.0/1.1. For example the logitech webcam i have will run at USB 2.0 bus no matter which port i plug into; the USB bluetooth always shows under USB bus regardless which port it use.

I have removed the eltima driver (USB Network Gate) and Virtualbox. Still not working.

Btw, the USB bluetooth is from Soundbots, i can't remember which model (SB340/341/342).

Attached updated ioreg, let me know what else can i try to do.

No experience with such old hardware. Problem is a USB problem... for you to investigate.

Think its about time for me to investigate Black Friday/Cyber Monday Deals

Thanks for the help.

I have an ASUS BT-400 which is showing up correctly in System Profiler - USB (see screenshot). However, in Blutooth, the MAC address is still 00:00:00:00:00:00 and while the Bluetooth icon is showing up in System Preferences and appears to be working, no devices will get listed. What did I do wrong?

 

[lulezi]

Solved it! What did the trick was disabling the internal bluetooth module of the GA-Z170N-WIFI by setting the bootflag

uia_exclude=HS08

so the ASUS BT-400 would be used.

Hi RehabMan,

I have exactly the same issue as documented here: https://github.com/RehabMan/OS-X-BrcmPatchRAM/issues/12

Attached is my ioreg and stuff. Can you help me out?

Your kextcache output (and ioreg) shows BrcmPatchRAM kexts are not installed.

 

[C0ltan]

Yes, if I install it I get a boot loop and can only boot via safe mode (and remove it.)

Boot verbose to determine why.

Note: Why do you have a kext patch in config.plist/ACPI/DSDT/Patches?

 

[C0ltan]

The kext patch is a mistake from me. I'm still working things out. When I boot verbose I get something exactly like this:

Apr 3 19:53:35 lightingdeMacBook-Pro kernel[0]: BrcmPatchRAM2: [0a5c:6412]: device request failed ("0xe00002ed (UNDEFINED)" 0xe00002ed).
Apr 3 19:53:35 lightingdeMacBook-Pro kernel[0]: BrcmPatchRAM2: [0a5c:6412]: Not responding - Delaying next read.

These 2 lines appear indefinitely and it doesn't boot at all then.
