I am unsuccessfully try to connect to a PR55-17A Wireless USB modem in Node-Red running on an Ubuntu OS. The modem works fine on my Windows laptop in Node-Red.
I am using the Wireless Gateway component. In Windows I configure the connection using COM5 and after Deploying the Gateway connects to the modem almost instantly. Using the same flow on the Ubuntu box, I configure the connection to the modem as dev/ttyUSB0 and after deploying it, times out with a “Request timed out without response”.
I have confirmed that the Wireless modem is dev/ttyUSB0 by listing the com ports available while the modem is plugged into the USB port then unplugging the modem and relisting the com ports. dev/ttyUSB0 shows on the list when the modem is plugged in and disappears when I unplug it.
Has anyone had any experience with this? Not sure how to troubleshoot it further.
