macOS VolumeName of USB device

[VijayKumar]

Hi,

Programmatically, I would like to get the volume name of a USB device. Using the sample code, I am able to get the IOUSBDeviceInterface for the device with matching product ID and Vendor ID. For this device, I need to get the volume name. Any help in this regard is highly appreciated.

Thanks in advance,
Vijay

Sorry I don't know the answer to that, but NSWorkspace does have a number of methods that deal with removable volumes, so that might be another way.

If you're accessing a volume, why go so low level and deal with USB driver code? Try reading "Low-Level File Management Programming Topics" in the docs and consider how you can identify what's available at /Volumes, perhaps using NSFileManager.

Best,
