Can I get some ideas on how to test a usb to mini usb cable? I am trying to use one with my ti 89. I can't tell if I have a defective cable or the software just sucks.

What do you mean "test"?

A plain USB cable is nothing but an "extension cord", any multimeter would do to check for it's continuity, BUT there are cables that include some current limiting hardware, and there is in practice (short of laboratory devices) no way to check if there is a "leak" or "cross-talk" at high speed transmission.

Be aware that there are cables that are "fully supporting" USB 2.0 speeds 480 Mbps and other ones that will only do the slower speeds like 1.5 Mbps, see also:

The simplest is to test the cable with another couple devices and see if it works or just get a new one.

Its not working so I want to know what the problem is. I'm thinking the software sucks or I have a defective cable. Mini usb is an old technology so I don't have any other devices that use it. Most devices not use micro usb.

Ok please clarify here AFAIK mini USB and micro USB are actually two different things.

EDIT - I just checked yes they are for sure two different things

The reference cable  is most probably to standard A connector (the "normal" USB connector on motherboards) and the standard mini-B connector (usually on external boxes ther staandard-B is used, lately on small boxes such as those for 2.5" disks it is replaced with the mini-B ), the micro-B is AFAIK/AFAICR only used in smartphones/tablets and similar:
