Android USBDevice: how to determine "vendor name" and "device name" from vendorID and DeviceID?

I have a USB device and I want to know how I can identify "vendor name" and "device name" from vendorID and DeviceID.

And the Device name I get from USBManagers' DeviceList Hashmap does not look valid.

Finally what I want is something like this:

(Silicon - Power 8GB)

In API 21 these methods were added. It's as simple as here:

    UsbManager usbManager = (UsbManager) getSystemService(USB_SERVICE);
        if (usbManager != null) {
            HashMap<String, UsbDevice> devices = usbManager.getDeviceList();
            for (String key: devices.keySet()) {
                Log.d(TAG, "Device Name: " + devices.get(key).getDeviceName());
                Log.d(TAG, "Manufacturer Name: " + devices.get(key).getManufacturerName());
                Log.d(TAG, "Product Name: " + devices.get(key).getProductName());
            }
        }

You could filter by vendorId and print it too.

You can get VendorId and ProductId from:

UsbDevice.getVendorId();
UsbDevice.getProductId();

You need to convert the int values to hexadecimal and compare them against a list of vendor ids/ product ids.

You can find this list here.

I'll leave the parsing to you, but it's pretty straightforward. You can find the structure at the top of the file:

# Syntax:
# vendor  vendor_name
#      device  device_name   <-- single tab
#          interface  interface_name   <-- two tabs
