Make sure the sound card is working in the VM and the USB driver is installed (check it with CFGSR).
Just made a picture of WinRadHD (V0.81c), ExtIO_Si570.dll running in VMWare player 3.1.3 on a Win7 74b dell e6510 laptop and included it in this mail (hope it will find the way thou Google and Yahoo).
The sound card is not that well. There is some more delay in the sound than running direct on the laptop, not that good for TX I expect.

Windows has many foibles, and USB devices equally share those foibles. However I do agree that the recent discussion is very much related to the behavior of USB devices under virtualization software, and this might not necessarily even be a function of Windows handling of USB devices. I would freely accept that the solution here may be in the hands of VMWare themselves...as this may be a bug in their software, in which case we can expect a solution to be some way away. I'm also aware that it's not only devices like Softrocks that display this behavior either - I know HTC phones also have similar issues under VMWare. However I do know the AVR / Obdev device drivers can work in a VM - as they are used in the VNWA, and I have no problems with that on my specific VM environment. Frustratingly the Softrock fails to enumerate though...
In my case I'd like to use a VM for convenience ... as the only physical Windows device I have is a work machine...and I really shouldn't be using it for anything but work. However I tried it out to prove my particular Softrock was built OK and worked on a standard physical Windows installation. It would be unrealistic to expect anyone to resolve this problem, but in the spirt of sharing knowledge I can contribute data about the observed behavior and I'm certainly willing to help someone (with more knowledge than I :-) ) diagnose the concerns - if there's enough interest. I have enough knowledge to obtain the Windows USB stack level events that occur....but sort of run out of steam at that point

The xtal speed from the internal RC oscillator is not that big problem. The inter RC is running on 8MHz and and drive a PLL to generate 16.5MHz to run theMessage 45 of 45 , Jul 27, 2011View SourceThe xtal speed from the internal RC oscillator is not that big problem.
The inter RC is running on 8MHz and and drive a PLL to generate 16.5MHz to run the code. The PLL is synced by software with the USB signals of the USB master (PC), not that big problem.
There is a problem with the at tiny avr chips and that is they are not designed (hardware and interrupt) to handle a USB signal's direct by hardware like a lot of the new avr (and other) microcontrolers.

I've strugged with this issue for several days, since I was stumped in the process of building my kit at the stage where the driver needs to be installed. "USB device not recognized" failure !!!
After considerable wild goose chasing, I've come to the conclusion it has to do with timing of the USB signals generated back from the ATTiny85. I remember a while back working with the PIC 18F14K50 and reading on the data sheet that, for USB, the microcontroller has to run on an external 48Mhz crystal-controlled clock instead of the internal oscillator, in order to meet the strict timing requirements of the USB protocol. Well, look at the ATTiny... it's running on an internal clock !!!!! (8Mhz). It's freqiuency drifts with temperature and voltage, according to the data sheet. It can be tweaked via firmware but there will still be variations from one device to another. That's why it works for some people but not for others, some of the time but not all the time. Sometimes it's on time, sometimes not.
With all due respect to the Softrock designers, we have a design flaw here. There are not enough pins for an external xtal on the ATTiny... plus the other tasks. We need a different microcontroller that can handle USB more accurately. How about the PIC 18F14K50 ?
