Here we go: http://www.usbgear.com/USB-Serial.html Some very cool stuff there. They also list the chipset used in some of those so you have some idea if it will work with FreeBSD. I think Vixie originally pointed me to this model: http://www.usbgear.com/computer_cable_details.cfm?sku=USB-16COM-RM&cats=199&catid=493%2C494%2C474%2C199%2C461%2C106%2C1009%2C601 If anyone has the lowdown on which chipsets generally work with FreeBSD (especially with all the changes in 8.0), that would be great. The above model works great on an old 4.11 box. It's an FTDI chipset - at the very bottom of the page they even claim FreeBSD and OpenBSD support. dmesg: uhub2: Genesys Logic USB Hub, class 9/0, rev 1.01/0.11, addr 2 uhub2: 7 ports with 7 removable, self powered ucom0: FTDI USB FAST SERIAL ADAPTER, rev 2.00/5.00, addr 3 [...] ucom11: FTDI USB FAST SERIAL ADAPTER, rev 2.00/5.00, addr 8 [...] uhub3: Genesys Logic USB Hub, class 9/0, rev 1.01/0.12, addr 9 uhub3: 4 ports with 4 removable, self powered ucom12: FTDI USB FAST SERIAL ADAPTER, rev 2.00/5.00, addr 10 [...] ucom15: FTDI USB FAST SERIAL ADAPTER, rev 2.00/5.00, addr 11 Charles > We have a 16 port model that's rack mounted and cost around $400.
