Hi. I'm Roy. I have a Pixelbook i5 128GB from, I think, 2017. Is it compatible with the "Universal Stylus Initiative"? I need to run Squid and the stylus that I'm using can only be held straight up and I cannot put my palm on the screen to help me write. I'm trying to write music for a music theory class at Queens College, CUNY. Any ideas? I see an advertisement for one made by iPlume, but I don't want to buy it unless I know it will work with my pixelbook and with squid.
