LibUSB Error suddenly appearing
I am using a MacBook M1 Max (Sonoma 14.6.1) and STM32CubeIDE(1.16.0) with a STM32g0316-disco
board.
Everything was working fine until, out of the blue, I started getting LibUSB errors when I tried to flash/debug my code.
I tried a second identical dev board and new cables and every usb-c port on my Macbook and the error persists.
I brought the machine up in safe mode and the error is still there. Here is the Error message from the IDE.
libusb: warning [darwin_open] USBDeviceOpen: another process has device opened for exclusive access
Device connect error
Error in initializing ST-LINK device.
Reason: libusb: warning [darwin_open] USBDeviceOpen: another process has device opened for exclusive access
libusb: info [darwin_claim_interface] no interface found; setting configuration: 1
libusb: error [darwin_claim_interface] could not set configuration
Failed to connect to device. Please check power and cabling to target.
STM32 STLink:
Product ID: 0x374b
Vendor ID: 0x0483 (STMicroelectronics)
Version: 1.00
Serial Number: 0670FF3936324D5043114936
Speed: Up to 12 Mb/s
Manufacturer: STMicroelectronics
Location ID: 0x00100000 / 1
Current Available (mA): 500
Extra Operating Current (mA): 0
And yet STM32CubeIDE cannot flash the board because it seems to think that (or is told by) Darwin (=MacOS) that the port is not available.
I'm not really sure where the problem is. I've tried reinstalling LibUSB as well but it makes no difference. What is particularly annoying is I cannot recall making any changes at all between everything working well and the problem appearing. I was happily editing my code and from one compile/flash to the next I problem appeared and will not go away.
Any ideas anyone?
