How do I fix Error: TI-89 Detected, but could not get status with the TI-89
using the TI Connect software for Windows?
The Operating System (OS) will need to be updated on the TI-89 in order for the TI Connect™ software to detect the status. Try the following procedure to install the OS from the TI-89 Boot Screen. Make sure TI Connect 1.6 is installed on the PC.
• Connect the TI Connectivity cable to the TI-89 and the computer.
• Do not start the TI Connect software.
• Download the TI-89 v2.09 OS onto the PC's desktop.
**Force TI-89 into "Boot screen" (See instructions below**
• "Press I to install..." ([ALPHA]. [ 9 ]).
• Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader.
• Follow the on-screen directions to install OS version 2.09.
The download should begin.
**Steps for Boot Screen:**
• Take one AAA battery out, press and hold down the Apps key while reinserting the battery to force device into the Boot Code screen.
• "Press I to install..." will appear.
Once the OS has completed installation, the TI Connect™ software will be able to detect the TI-89.

SOURCE: i get a pop-up ballon that says "USB device not recognized"

k.....so i had the same problem but i figured out whats up...

if you find another 89 that is the same model....for example if you have a titanium.....find another titanium....and get a var link cable and plug em in to both calcs......

on the one that is working hit 2nd "-" to open up varlink.

hit F3 to open up "link" and highlight send OS but dont send it yet.

On the calc that isnt working correctly open up varlink (2nd "-") and hit F3 and highlight and click recieve OS.

Then on the calc that is working click send OS.

THis will erase your applications like notefolio and other things but once your calc recieves the OS you can go back to varlink and send all the "flashapp" files.

Just make sure when you use varlink you always click recieve before you send it.....otherwise it will give you an error.

hope this helps

Tip

When installing a Web-Cam make sure your old cam has been uninsulated.


When you set up a new Web-Cam for your computer go under to the computers Start up Key, click the "Computer" button, and you will see a option to pick from. Click "Control Panel" and a list of installed programs, and accessories installed in your computers memory will come up. Find your old Web-Cam under the installed "Device Manager" icon.
Uninstall your old cam, and make sure the New one IS NOT plugged in at this point. After you uninstall the old one, you can then PLUG in the new cam, go back to "Device Manager" and click on "View Hardware and Devices" and your computer should recognize you have new hardware plugged into one of your USB ports, and a balloon should pop up, and Click that ballon, your computer SHOULD read and install the Cam, if not use your "Device Manager" and IF a disk came with your Cam, put it into your computer at this point if you already havent. Your PC should recognize what you are tring to do, and install the Cam. Hope this helps, if not type Web Cam into the search engine in your computers search tab, while under the Device Manager, and it will tell you step by step on how to do lots of things.

USB Device not Recognized


The camera should have come with software which includes the correct drivers. Did you install the drivers before connecting the camera? The camera simply may not be compatible with your OS.
