Tascam has a new line of entry level interfaces with drivers that have buffers as small as 4 samples (on Windows)! This is over a USB-C connection.
This is the smallest asio buffer size i am aware of on any interface. With some RMEand Focusrite buffers around 3ms at 64 sample, are we approaching sub-milisecond lantencies over usb? This would be awsome! Ill keep my eyes open for latency specs, as i have not seem them yet.
Just thought it was an intersting innovation, and a good sign for interfaces of all ranges.
