I recently downloaded a few applications for my TI-89 Titanium, but find that any and all files that I try to transfer to it end up like this.
"USB communication error: Cancel(8C08CCCC)"
Can someone help me with this? My files have all been unzipped, the TI-89 connect has been installed, the device has been located, and there are absolutely NO files on it except the ones that it came with.
Thanks

I remembering other people having this same problem. Supposedly, it just started working when they tried to transfer the files again. Make sure that the USB cable is securely connected to the port in your computer.
