uuu@: IOUSBUserClientLegacy::start: missing entitlement com.apple.ibridge.control with uuu on Mac

[michaellihs]

When I try to flash a (proprietary) hardware device from my Mac (macOS Mojave 10.14.6), I get the following error message in the terminal:

$ sudo uuu xyz.uuu
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.4.43-4-g9aff92a

Success 0    Failure 1

20:32    1/ 0 [Failure open usb device,Try sudo uuu  ]

After reading some posts around this issue I was made aware of checking dmesg entries and see the following log:

uuu@: IOUSBUserClientLegacy::start: missing entitlement com.apple.ibridge.control

Is that a know issue when using uuu on a Mac or something I did wrong? Can I somehow work around this / fix this?

Before using uuu, I run the following script to build it on my Mac (that should show dependencies and 3rd party libs used):

#!/bin/sh

git clone https://github.com/NXPmicro/mfgtools.git
brew install cmake openssl pkg-config libusb libzip

sudo ln -s /usr/local/Cellar/[email protected]/1.1.1g/lib/libcrypto.1.1.dylib /usr/local/lib/libcrypto.dylib
sudo ln -s /usr/local/Cellar/[email protected]/1.1.1g/lib/libssl.1.1.dylib /usr/local/lib/libssl.dylib

cd mfgtools
cmake -DOPENSSL_CRYPTO_LIBRARY="/usr/local/lib/libcrypto.dylib" -DOPENSSL_SSL_LIBRARY=/usr/local/lib/libssl.dylib .
make

Thanks for any help!

it need unload HID driver. but it is fail at latest MAC OS. It need a sigature to unload driver. but we still not get sigature from apple yet.
kextunload -b com.apple.driver.usb.IOUSBHostHIDDevice

[michaellihs]

Hm - I assume, since

kextunload -b com.apple.driver.usb.IOUSBHostHIDDevice

returns an error message, namely

(kernel) Can't remove kext com.apple.driver.usb.IOUSBHostHIDDevice; services failed to terminate - 0xdc008018.
Failed to unload com.apple.driver.usb.IOUSBHostHIDDevice - (libkern/kext) kext is in use or retained (cannot unload).

I cannot unload it and have to wait for you to get the signature from Apple and change this in the code - right?

That's what I get so far. May you look for the other solution.
