[SOLVED] LibUsb.open error (Device Collission with Root hub)

LibUsb.open error (Device Collission with Root hub)

Code Snippet

deviceHandle = new DeviceHandle();
int isDeviceOpened = LibUsb.open(device, deviceHandle);

Output:

isDeviceOpened: -12

Errors:

libusb: error [init_device] program assertion failed: device address collision with root hub

org.usb4java.LibUsbException: USB error 12: Unable to open USB device: Operation not supported or unimplemented on this platform

libusb: error [winusbx_open] could not open device \\.\USB<some chars here> #{some chars here} (interface 0): [5] Access is denied.

I already updated the driver using Zadig and I still encounter this. Anything else to check?

Solution

The issue seems to be that I did not trigger LibUsb.freeDeviceList(devs, unref_devices); , I figured it out when I disconnected the USB device manually and successfully connected it when it is freshly connected.
