What USB to serial adapters are known to work, and how have you used them? I've tried a Keyspan USA19HS and F5U409 and neither seem to. I'm trying to get serial up under java.

When I plug a USB/serial into a port /dev/ shows some new devices usbdev2.x_epyy, where x seems to be a count related to how many times I've plugged something in, and y = 00,01,02,03,81,82. |
