OMAPL138 EVM: Virtual COM Port Not Installed for Device Port
I'm using the OMAPL138 eval board, trying to run the USB-dev-serial starteware code. I'm able to load the code through the debug port without any trouble, and under the Device Manager, I can see the "Stellaris Virtual Serial Port" for the debug port. When I plug in the device USB port, however, I see the install window attempting to install the "Virtual COM Port." When it appears to have finished and I look in Device Manager, I don't see a new COM port. Instead, under "Universal Serial Bus controllers," I see a new "USB Composite Device" with the yellow warning symbol in the lower right corner.
The starterware code for HID and mass storage works well, but the serial enumeration is suspending in between, ie after the device configuration response is send, a suspend interrupt is detected.
Thanking you,
