if that shows basically the same as lsusb then this is a no.
I checked with the ivyrain developer and they weren’t sure why it wouldn’t work either.
I have also found a user that wanted to install the same modem into their thinkpad, and they were discussing an issue I haven’t thought of yet: Does the modem work purely off usb or is the usb interface solely for the serial interface?
If it’s just for the serial interface then this is a lost cause…
