Testing a synthesizer

[Cheryl Homiak]

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.

Hth.
