Dear sir, It correct way to use node-red to read data 10 to 20 devices by using 1 USB connector, but you can use timer to read trigger to read data. You cannot read data from 5 or 10 devices the same time. I mean you can create timer to read data for device number 1 with 1 sec, device number 2 with 2 sec, ....device number 20 with 20 sec then you read data properly. Thanks!
