I'm way behind in my mail today so if you've already solved this, just ignore. I did some googleing--google is your friend. I didn't do it sooner because I thought you had probably done so before posting but I should know always to google and never to assume. At any rate, it does appear that your dynex has the prolific chip, with which I am quite familiar having used it extensively. It does appear to need a driver unless something has changed since 2008. There are two sources for a prolific driver, well three if you count just using your cd. Your choices online are as follows: http://www.prolific.com.tw/eng/downloads.asp?ID=31 There are lots of drivers shown on this page so be sure to get the one that is a universal binary; I believe it's the first one after all the Windows drivers. If you download this .dmg file, and follow the instructions, you should have the driver working as /dev/cu.usbserial and/or /dev/tty.usbserial. I've usually used the cu one but I can't remember whether or not it matters. Your other choice is found at sourceforge: http://osx-pl2303.sourceforge.net. I don't think I've used this one though some posts I read said it worked; it's not clear to me if the driver shows up with the same device names I've listed above or not but if you use this driver you can use the method of plugging in your cable and checking dmesg using sudo.
