I have a MSP430 Launchpad (microcontroller) which forms a virtual serial port on my Windows 8.1 rig. Somehow I cannot receive/send any data through this serial port on this rig. I have tried 2 other PCs (both Windows 7) and they work fine, so I suppose we can rule out the possibility of a faulty microcontroller. The device appears to be fine in device manager (no exclamation or error marks) but does not appear when I run PortMon, any idea how can I run further diagnostics to narrow down the offending driver(s)?

Does the device appears under Ports (COM & LPT) node? – drk.com.ar – 2014-06-14T14:52:09.297
Yes it does, but no data comes in/out – paradox – 2014-06-14T14:54:07.653
Maybe it obvious but have you tried changing the COM number? Have you checked the bps and parity configuration? – drk.com.ar – 2014-06-14T15:17:25.013
Yup, I have tried that to no avail – paradox – 2014-06-14T15:20:00.960
TI driver includes FTDI driver in the ZIP file. Have you installed them? http://www.ti.com/tool/msp-exp430g2#technicaldocuments
– drk.com.ar – 2014-06-14T15:26:53.987Which one? If it's 430cdc.inf I have tried that before – paradox – 2014-06-14T16:04:38.883
In this ZIP file: http://www.ti.com/lit/zip/slac632 there is two directories. Both seem to be different drivers for USB-Serial. Even those inside stellaris directory. Which are the FTDI I mentioned before.
– drk.com.ar – 2014-06-14T16:12:27.710The stellaris drivers are for a ARM processor, I tried with the ones under slac632\msp430\USB_CDC and they are the same – paradox – 2014-06-14T16:16:51.477
