testing a usb to mini usb cable

Do you have another device that uses a mini USB port? Camera, MP3 player, etc?

Yeah, try the cable on another device, or try another cable on your TI 89.

I can't tell if I have a defective cable or the software just sucks.

Hmmm - In reading the manual for your TI, it is not really clear but it appears the USB cable for data transfer is not a standard USB cable used for charging.

In amazon, if you search for TI 89 USB cable you get a bunch specifically listed for TI devices, including the 89.

As seen on the official Texas Instruments TI-89 Accessories Page, listed are two USB cables and the TI Connectivity Kit which includes cables and software. I suggest you study these options to see which one you need, then shop for it.

You don't own enough tech toys. :p Kidding aside. It's about 50 50 here. I have some older stuff with the mini and some new tech with the micro usb. I have half a dozen or so assorted USB cables hanging on a coat hook next to my desk. Most were just for charging the batteries in said device.

Buy another lead is the obvious way.

For a quick look, physically examine the plugs/sockets for damage, with a good light and a magnifying glass. That won't tell you about the rest of the lead though.

You can test for continuity plug to plug on the lead with an ohmmeter/multimeter with small enough probes, mine are far too chunky for that job and would need some fine wire added to get into those small plugs.
Possible to do but fiddly, hardly worth the effort.
