Question about Texas Instruments TI-89 Calculator
Under that is says "ONe of the USB devicesattached to this computer has malfunctioned, and Windows does notrecognixe it. for assistance in solving this problem, click this message." i clicked on the ballon and it said that i didn't have a driver installed, but i have TI connect installed. please help, thank you
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

Tips for a great answer:
Open up Device Manager.
Scroll to the USB controller and click the +. Turn the calculator ON then connect the USB cable to your PC. A new device will appear on the USB controller.
Right-click on the new device and, choose Update Driver Software. The Hardware Update Wizard will appear.
Choose "Browse my computer for driver software".
In the search field type in C:\Program Files\TI Education\Driver Files. Look for the tiehdusb.inf driver file.
Click on Next to finish installing the driver properly
Once the driver is installed click Finish.
Now click on the "Ti Connect" software on your desktop. Double-click the Ti Device Explorer located to the left inside the Ti connect window.
The software should start looking for your calculator. A pop-up should display looking something like what is pictured below. Under device your calculator should display. If your calculator is located the software will highlight on to it. Click, "Select" and another window should pop-up.
The next pop-up should look something like this. If your Ti 89 is present it will show up next to device and, probably won't say Titanium. Your cable type and port should be listed too.
If all the information is correct in the window that appears click "OK" and, you should be able to start downloading. You can skip the rest of the procedures. If your Ti 89 still won't connect to the computer goto Procedure 3 unless you have already tried Procedure 3, then goto procedure 4.
If the above procedure still does not help then try un-installing and, re-installing the Ti Connect software. After un-installing re-boot your computer. After re-booting your computer you can get the latest copy of Ti Connect software by going to the Texas Instruments web site. You can get to that site instantly by clicking, "Ti Connect software" At this Ti site under "View: Connectivity Software", Click, "the OS link that applies to your computers operating system". Next, click the Download Item, "Ti Connect software for ....OS". Next you can login or, click "continue as guest". I'd would click the "continue as guest". Once you have click, "continue as guest" the Ti Connect software for ....OS will be download to you. Click, "Save" and then a folder will pop up. It is probably a folder that you download too. If so, you may want to change it and, 'Save as" to this folder, "Desktop."
Next right-click the Ti Connect executable on your desktop and select, "Properties." Then click the "Compatibility" tab located at the top of the "Properties" window. Click the box next to "Run this program in compatibility mode for." and select "Windows XP Service Pack 2" from the drop-down menu. Click "Apply" and choose "OK." Double-click the TI Connect executable and select "Next" to begin the installation. Click "Yes" to OK the installation process to proceed. Then click "Finish" to complete the installation. Next, reboot your computer.
Now go back and try Procedure 1 and 2 again. If you have already tried Procedure 1 and 2 twice, go to Procedure 4.
If the above procedures fail then try a different cable and if possible a different computer.
If trying different cables/computers fails, please contact and fill out a Ti Cares Customer Assistance Form. You can get there by clicking this link, " Ti Cares Customer Assistance Form "
