I'm testing USB CDC based on an example source from Xilnx.
Please refer to http://www.wiki.xilinx.com/Zynq-7000+AP+SoC+USB+CDC+Device+Class+Design+Example+Techtip.
This example code works well, for first connection, but re-connection does not work.
After resetting or rebooting Zc702 board, I cannot connect to the virtual COM port anymore.
I can see the COM port in the device manager, but Tera Term does not show up the COM port.
I use window 7. Is this windows COM port driver's problem? or the example code has some bugs?
please help me...
