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.

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

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?
NetRock6

ASKER
There is APP that uses this USB device. Cannot use the Virtual Sound.
I found this link:
http://communities.vmware.com/message/416893#416893
will try to see if that helps, till some one comes up with a better solution!!

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.
