Change seed USB logger baud rate

My product requires a raspberry pi in addition to the Daisy Seed. Would be great to get real communication over the USB connector I’m using to power the seed from the RBI USB A connector. I outgrew 9600 baud somewhere in the early 1980’s. It’s not obvious from the examples nor libDaisy how to do this increase the baud rate. I’m also struggling to get by-directional communication as well. Clearly there are other hardware options but I want to know what the limit is here before I move on.
