Hi,
I have a design where I have implemented MSP430F5510 as USB HID device in which Vusb is powering up my entire board. Using this configuration if I Power up my board using Vbus it is running successfully as a USB HID device. But as a second alternative as I Power up the board externally using 3.3V LDO present on my board, USB HID device is not recognized by PC.
In Second case I made the USB section only Host Powered and powered up my board externally (not from Vusb), In this case Enumeration did not happen. USB gets reset and then suspended. Kindly help me out this. I am using USB Developers package from TI.
Thanks
Praveen
