Someone from the Sun's USB group (or a member of the larger opensolaris community, says he, hopelessly) needs to look into this, yes. When I was working on the usbsacm prototype several years ago with a loaned Novatel V620 card on Verizon 1xEV-DO, I tried some broadband speed tests and was getting from 700Kbps to 1Mbps depending on signal quality. Same card on the same laptop produced up to 1.5Mbps on Windows. But that was then, when skies were higher and bytes were bigger :) -Artem
