have you successfull connected to the Guest VM, did it plug and play and install drivers?
also remember that not ALL USB devices are supported!

Yes. it is successfully connected to the Guest VM, and set as default device for communication. Everything looks good as far as i see.
drivers installed?
is it in the control panel /device manager / sound as a device with no yellow checkmark ?
ASKER
No Yellow Check Marks.. It is installed correctly. I was wondering if the device has an issue!!
Tried out on physical PC and no sound!! i will try on different PCs.

I have "Buffer Full" error, once i connect the USB device to guest PC. is there a way to expand the buffer size of the USB in the guest PC.
I believe this was fixed in late versions of workstation 7.1.5, or was an issue with web cam devices
ASKER
Sorry, i get error: "Audio Buffer Full" . so i need to change the size of the Audio Buffer not USB. In Physical PC i have no issue and have a clear sound.
out of curiosity why are you not using emulated virtualised sound in the VM by adding virtual sound?
ASKER
There is APP that uses this USB device. Cannot use the Virtual Sound.

The link did not help. But i was able to find out that the external USB device sends packet of 512kb and older model sends 1024.
With older model i can get output but with newer model, sends 512kb, i can not. it seems that i need to increase my host (VM) performance, But how can i increase the performance to handle block of 512kb packets from USB port. Basically, need more CPU power to handle the process.
