WICED BCM4343W_AVN with Tiny-H JTAG doesn't work when trying to program code

[jmartin]

The wiced development platform comes with 0.9.0.
I'm using the build command "valve-BCM94343W_AVN JTAG=Olimex_ARM-USB-TINY-H download download_apps run"
I get the following:
"**** OpenOCD failed - ensure you have installed the driver from the drivers directory, and that the debugger is not running **** In Linux this may be due to USB access permissions. In a virtual machine it may be due to USB passthrough settings. Check in the task list that another OpenOCD process is not running. Check that you have the correct target and JTAG device plugged in. ****"

Which driver should I be using?
I have Zadig installed and get different errors in the log file for the libusb-win32 and winusb drivers.
