Arduino Mega not connecting to PC

[surfdabbler]

I have an Arduino Mega, and it's not able to connect to a particular PC. It connects fine to my laptop, but when I put it into the production environment, the PC does not recognise the COM port.

I have tried installing the FTDI drivers, and then uninstalled that and installed the whole Arduino IDE to try to get the drivers from there, but it's not recognised.

Device Manager shows the "USB Serial" under "Other devices", but has the little warning icon to say it's not working. Under properties, it says...

The drivers for this device are not installed. (Code 28)
There are no compatible drivers for this device.
To find a driver for this device, click Update Driver.

... and under Details, Hardware Ids, it shows the following value...

USB\VID_1A86&PID_7523&REV_0264
USB\VID_1A86&PID_7523

... which doesn't include "FTDI" anywhere, so maybe I need different drivers? Update Driver does not find any compatible drivers.

Any suggestions?

You can check on your laptop which driver is used.

You can also look up the VID and check who the manufacturer is.

There are barely any Mega boards that use FTDI. It's either 16U2/8U2 or CH340.

Ah, great suggestion. I will try this. Thanks.

Success! I didn't copy the drivers from my laptop in the end, but I checked what driver was being used, downloaded the CH340 driver from the net, installed it, and it all works. Thanks for the help.
