MSP430 5529 Rev A enumeration fails (USB)

Barteit

Hi,

I am having problems with the USB enumeration on the MSP430 5529 Rev A.
I am using the CDC API from TI with Code Composer Studio Core 4.2.1.00004 and a TS430PN80USB Board.

The microcontroller will go into ST_ENUM_IN_PROGRESS, when I start it and stays there.

The virtual com port is showing up in the windows device manager and the driver is installed.

The HID example does go into the ST_ENUM_ACTIVE state, but I have to get the CDC examples to work.

I now tried the CDC + CDC example and it works.
But the CDC examples still don't work.

Now it is working. I don't know why, but after trying the CDC+CDC example and then again the CDC only example the microcontroller is working.

Changing the descriptors.c in the slac285b ecamples to

0x02,                                   // Device's base class code
0x00,                                   // Device's sub class code
0x00,                                   // Device's protocol type code

solved the problem.
In the slac285c examples this problem is corrected and does not occur.
