usb cdc host demo

Hi,

I'm running the USB CDC HOST  demo on TWR-K64F120 + TWR SER2 board.

To test the demo the documentation calls for another TWR-K64F120 board configured as USB CDC device.

Since I have just that one board ,I decided to attach a USB_RS232 bridge and see if at least the HOST would attach  and numerate by placing breakpoints at relevant locations in the code.

So I connected the Bridge to the Host_only USB(type A) connector on SER2 board .I shunted J16 and J21 to

 

Connect USB VBUS OC and USB VBUS EN to Elevator.

This is not working for me. I noticed that when I connect the USB-RS232 bridge to a host PC, power is supplied to it by the PC however when I connect the device to my board there is no power applied to the device.

maybe this is the issue, I'm just reaching.

I've also noticed that all my questions on USB have gone unanswered ,Don't know why.

Please I need all the help I can get.

 

Thanks,

Koorosh Hajiani
