Here is the connections I have:
Here are the connected pins:

Hi vbergeron,

please can you tell me on which board your TC233 is running on? If you have a PCB developed by your own, it might be just an electrical problem.
Since PC-USB needs to see 5V, your Vcc might be to small. Another reason could be the board itself, where you might have used one of the JTAG pins
for other program based purposes.

Regards,

Jens
