LibUsb.open 错误(设备与根集线器发生冲突)
LibUsb.open error (Device Collission with Root hub)
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?
问题好像是我没有触发LibUsb.freeDeviceList(devs, unref_devices); ,我在手动断开USB设备连接并在刚连接时成功连接时想通了。
