我想在java中使用usb4java lib读写sandisk usb数据。
我可以获取 USB 设备列表。
但我不知道如何读取我的 USB 数据。
这是我的转储 usblist 代码。
{
// Create the libusb context
Context context = new Context();
// Initialize the libusb context
int result = LibUsb.init(context);
if (result < 0)
{
throw new LibUsbException("Unable to initialize libusb", result);
}
// Read the USB device list
DeviceList list = new DeviceList();
result = LibUsb.getDeviceList(context, list);
if (result < 0)
{
throw new LibUsbException("Unable to get device list", result);
}
try
{
// Iterate over all devices and list them
for (Device device: list)
{
int address = LibUsb.getDeviceAddress(device);
int busNumber = LibUsb.getBusNumber(device);
DeviceDescriptor descriptor = new DeviceDescriptor();
result = LibUsb.getDeviceDescriptor(device, descriptor);
if (result < 0)
{
throw new LibUsbException(
"Unable to read device descriptor", result);
}
System.out.format(
"Bus %03d, Device %03d: Vendor %04x, Product %04x%n",
busNumber, address, descriptor.idVendor(),
descriptor.idProduct());
}
}
finally
{
// Ensure the allocated device list is freed
LibUsb.freeDeviceList(list, true);
}
// Deinitialize the libusb context
LibUsb.exit(context);
}
此代码打印出所有 USB 设备。
但我想检查一次我的sandisk设备。
如何更改我的代码?
