LPC214x usb driver for windows 7

guillaumelesieu — Tue, 03 Apr 2018 11:48:58 GMT

I'm working with the mcu LPC214x (LPC2141). I need a usb driver (vcom) for Windows 7, 64 bit.

Does nxp provide this driver ? (or for Windows XP or vista)

Thanks in advance.

Best regards.

Copied from MCUXpresso IDE 10.x, it should work for all LPC family MCUs. You do need to modify PID/VID pair to match your application.

Thanks for your answer.

The different files [.inf] work for Windows 7, 64 bits ? What's the difference between them ?

Hi Guillaume,

In general, you cannot use a single INF file that differentiates between device installations that are based on the operating system version. For example, if the files or registry settings that support a device differ between versions of x64-based operating systems, you must create an operating system-specific INF file for each version.

Hi,

Ok, I understood.

In the folder "lpcopen_examples_windows_usb_drivers_v1.20" there are 4 files :

- lpc-ucom-vcom

- lpc-composite-vcom

- lpc-composite89-vcom

- lpc-composite89-dfu

So, each file correspond to an operating system version, because there are no a lot of information in each file about the version.

Thanks.

Regards.

Just use "lpc-ucom-vcom", the other are for different USB classes. usbser.sys should be provided by Microsoft. There are plenty of info. on "how to install VCOM driver manually from Windows" online.
