Usb communication error: unexpected packet ( 8C080008)
« on: October 26, 2010, 08:17:17 am »
Howdy everyone, I have ti nspire with 84+ keypad on it.

I connected PC and Calculator using the USB Cable. Installed TI Connect and then went to DeviceExplorer, and the program managed to find my calculator and open the device explorer correctly.

However, when I try to transfer programs (by dragiing them to the TI Connect Interface), I get this error message:

Usb communication error: unexpected packet ( 8C080008)

I have no idea of what it means and google is not helping me.

The USB Port is fine I tested it with a Pen drive. However, I can't transfer files.

Help me please,

David

I alse got that error serveral times before I switched to TiLP. It occurred when my batteries where lower than half loaded, and when I tried to send files to archive. That's what I remember from those old times. I hope it helps. You can allways switch to TiLP :P

No matter how many errors are bothering you, always try to stay rel-Axe!

That, IIRC, is basically when Ti-connect gets a packet it doesn't want to parse, or doesn't want to parse just yet.  If you can give me a log of the USB transfer (plain text, preferably), then I can probably help.

I've managed to put a few things in Calc: Doors and two games.

However, I did it once, never again can, it says:

'Unable to communicate with your calculator. Please try again later'.

No luck for me, ouch

Remove the drive that TI uses, and then re-install it. (The entire package)  Then, try it.

If you are going to use TiLP, don't expect to be able to fall back on ti-connect. TiLP makes installing ti-connect twice as hard. Your problem could be related to low batteries, but here's a nearly sure way to get ti-connect working again.

1. Plug in your calculator
2. Go to device explorer and uninstall it
3. Repeat 1 and 2 for any port you think you may have plugged your calc into
4. Uninstall ti-connect
5. Go to your drivers, and delete libusb0
6. Restart computer
7. Reinstall ti-connect
8. Plug calculator in and let it install
9. It should work

You can build a statue out of either 1'x1' blocks or 12'x12' blocks. The 1'x1' blocks will take a lot longer, but the final product is worth it.

I come here, choose USB then TI and then I uninstall and reinstall?

This for TI Connect.


Gave up TiLP

That's could potentially work. If it doesn't, I mean do that then reinstall ticonnect as a whole.

Unless you can give me a log in some readable format, I can't help you.  What OS is this?

Go to your drivers c:\windows\system32\drivers\ and highlight libusb0. Who made it?
