I'm having exactly the same problem, but I do have USBAUDIO.sys in my windows/system32/drivers folder. I don't know if it'll be any use, but I've attatched my own USBAUDIO in case, not sure how you'd go about installing it or whether it would be compatible.
I tried contacting razer, but once I confirmed the Megalodon was working in another computer, gave them a list of my computer bits:
Intel i7 4770k cpu
Gigabyte G1.Sniper 5 motherboard
G.Skill F3-2400C10Q-32GTX memory
OCZ Revodrive 3 x2 pcie ssd
and and asked about any known compatibility issues they said:
Since the device is working fine in another pc, this issue can be caused by the drivers inside your current pc. We have check the specs of your new pc and we found out that the device works for other customers. Since this is out of our support boundary, please contact your computer manufacturer to get this fixed.
And since I'm my computer manufacturer that puts me back on forum trawling.
I've also found a drivers folder in the program files for the firmware updater, but that wasn't any help for me. selecting the .inf file through the "have disk" button says
The folder you specified doesn't contain a compatible software driver for your device. If the folder contains a driver, make sure it is designed to work with Windows for x64-based systems.
I've also tried having driver updater scan the entirety of my previous computer's c drive, but it didn't find anything.
Next I'll try contacting the motherboard support people and editing the .inf file to convince windows to accept it, but I don't really know where to start with that. I'll try looking for some kind of detailed error log from the failed "have disk" attempts.
There's still a chance though, that the driver folder in the firmware updater files is only for recognising the megalodon while it's in firmware update mode. Other computers see it as an entirely different device in that mode.
