[WP-34S] Troubleshoot internal USB Board

[Sanjeev Visvanatha]

Hello All !

I have a WP-34S that I added Harold's USB internal board. I cannot get the USB to transfer I/O between the emulator and the device. How do I go about troubleshooting this?

The USB seems to connect to my Win 10 machine, and I get a FTDI device on a virtual COM port in Device Manager. I also can see that the device is being powered from the USB port as I can remove batteries and operation is not interrupted.

Thank you in advance for any pointers.
