java - LibUsb.open 错误（设备与 Root 集线器冲突）

Question

代码片段

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

输出：

isDeviceOpened: -12

错误：

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.

我已经使用 Zadig 更新了驱动程序，但我仍然遇到这个问题。还有什么要检查的吗？

Answer 1

问题似乎是我没有触发 LibUsb.freeDeviceList(devs, unref_devices); ，当我手动断开USB设备并在新连接时成功连接时，我想通了。
