have been trying to upgrade xmitter for many months still cannot connect to update program

seems im having the same issues. i cant get my 7e to connect to the computer. how were you able to get it to connect?

I held the ext button and turned on the xmitter it connected but will not update

• Uninstall Defuse completely and reboot.
• Use Device manager to view hidden USB devices and remove any drivers.
  
• Install Defuse 2.31.
• Open the Device Manager and connect your Devo. If the driver is correct it will show up as "STM Device in DFU mode" under Universal Serial Bus Controllers, and Defuse will see it.
• If it's not right, Device Manager will see "STM32 DFU" under Universal Serial Bus Devices, but you can then right click on the device, select Update Driver Software, select Let me pick...choose Universal Serial Bus Controllers, and select STM Device in DFU mode. This should allow Defuse to see the Device.

I've done this a few times recently because I'm messing with other STM devices. YMMV.

not my problem problem is defuse can not find the library files to update xmitter

Thanks for the help. That solved my problems.

that's great where do you find the library files to download for the upgrade

I noticed my Devo 7e is very picky when it comes to USB cables...
Some work, some just don't.

I have no problem with connecting to USB just can not find the necessary files to upgrade transmitter

They were in the file I down loaded from the deviation website. Then you have to unzip the files. Once you've done that you should be be able to find the file where ever it was down loaded. I'm only good enough to be dangerous with computers so it was a lot of trial and error for me, and I'm probably not the best person to be giving advise.
