works on some laptops usb, on my precision 5520, works only if i use a hub connected to usb-c. for the other two usb ports it doesn't gets identified. other usb peripherals like flash drives and ttl, j-link do work with those ports. so its an integration issue of some kind. when connected seems to work ok, though i was unable to get it to connect (if i connect the ec25 modem to sbc it does connect).
Didn't received my goods
