MSP430F5522 USB CDC Drivers

A while back, I made some MSP430 USB development dongles and the hardware worked fine. I tested out the USB capability with the downloadable examples in the MSP430 USB Developers Package (3.0). I started modifying the code and playing around with it and stuff worked pretty well. Then, I got to messing around with LabView and it's driver wizard and I think that is when things went sour. Shortly after, The CDC examples stopped working. I recently found that the HID and mass storage examples still work fine, but windows is not finding a driver for the CDC examples.

I installed a fresh copy of the MSP430 USB Developers Package, so, I know the code is not the issue. When I plug my device into my laptop (running any of the C1 through C6 examples), instead of the  "dun DUN" sound windows makes, I get a "dun dun dun" sound after a second or two. I've checked my device in device manager and it says it has a problem and that there are no drivers found for it.

Are there specific drivers for the CDC examples? I want to use this as a virtual com port so that I can send/receive data through LabView. Thanks! 

  • Ok, problem kind of solved... I tried updating the driver and I'm using the default "Application UART" from TI and I'm now able to send/receive data. However, isn't there a generic driver that Windows will automatically load? I plan on this being a commercial device where the user just pops in my gadget and Windows finds it on it's own.
