Hi Kumar,

If you are looking for a USB driver of a specific Device, the option could be contacting to the Device manufacturer, they use to provide Linux drivers.

Regarding LPC side, most the USB libraries of the used operating system provides HID support, and it is the class of the barcode readers as generic devices, so, it could be another option.

Hope this will be useful for you.
Best regards!

Hi Kumar,

As the LPC2xxx are legacy devices, the available software is limited and generally provided by 3rd parties. AS example, you could refer to the following link for further details regarding USB support with HID Host capabilities on Segger emUSB:
