First off: Thank you the-darkvoid and RehabMan for you hard work! I would never have my Hackintosh up and running if it wasn't for all of your guides and posts and help.
GBU521W6 / BCM20702A0
Product: 21e8
Vendor: 0a6c
Supposedly working out of the box...
I have been struggling with the IOGear GBU521W6 for at couple of days now and have tried a multitude of things. Any help will be greatly appreciated.
Here is my current status:
USB device is recognised in system profiler:
View attachment 347295
Which leads me to think it is not a USB issue - But is that correct?
In /S/L/E:
BrcmFirmwareRepo.kext
BrcmPatchRAM2.kext
(Both at version 2.2.10)
During boot I get "could not open device!":
Code:
Accelerator successfully registered with controller.
BrcmPatchRAM: Loaded firmware "BCM20702A1_001.002.014.1502.1764_v5860.zhx" from resources.

BrcmPatchRAM: Firmware is valid IntelHex firmware.

The firmware seems to be compatible:
In Windows I have verified that the dongle works with the older driver
BCM20702A1_001.002.014.1443.1459_v5555.zhx...
However using BrcmFirmwareRepo.kext and BrcmPatchRAM2.kext in version 2.1.0 which loads this earlier firmware...
I also get the same:
"BrcmPatchRAM2: uploadFirmware could not open the device!"
