I'm working on a FRDM-K64 with a USB-CDC sw. After some problems I'm now able to sometimes get it to connect to my PC and communicate.
For the moment I'm using Win-7, TeraTerm and the FRDM-K64.
When I stop my target windows removes the serial port, (pling-plong) and TeraTerm disconnects.
When restarting the target windows re-connects the serial port, (pling-plong), but often the serial-port is not visible to TeraTerm,
(COM-24 is not visible in the COM drop-down list). The Computer --> Manage --> Device Manager shows COM-24 as OK and working.
I've tried to disconnect the COM-24, and re-connect. The re-connect typically ends in an infinite loop, and I have to re-boot my PC.
How am I supposed to do development work on the CDC device???
