My Windows 10 PC contains a Sonnet Technologies USB3C-2PM-E but no Thunderbolt 2 interface. To connect my Pegasus R4 to the Sonnet card I'm using a StarTech.com Thunderbolt 3 to Thunderbolt 2 adapter.

As described at the user manual I first installed the Pegasus drivers and after that the Pegasus Utility. But when starting the Pegasus Utility the message "Device Not Found!" is shown.

Hi Sven,

We have discovered a problem with the Windows driver on the support page, it will be replaced soon.

Please use the driver from this link.

I have updated the driver and restarted the computer, but I'm still getting the "Device Not Found!" message at the Pegasus Utility.

I checked also the Windows Device Manager. There is listed the "ASMedia USB 3.1 eXtensible-Hostcontroller – 1.10 (Microsoft)" - but I can't find any entry that relates to the Pegasus R4. Same at the Partition Manager.

Is there any other way to connect the Pegasus R4 to the computer that doesn't need the StarTech adapter? I have already looked for a PCIe card that directly supports Thunderbold 2. The only thing I found was the "HP Thunderbolt-2 PCIe 1-Port I/O Card" - could that possibly work better than my current setup?

Hi Sven,

It seems that the Windows drivers are different from the MAC drivers. With the MAC driver macOS will see a Pegasus 1. But I just tested with Windows 10 and the latest driver and neither a Pegasus 1 or a Pegasus 2 was recognized. The Pegasus32 comes right up, as does a Pegasus 3. The only difference is that I am connecting the Pegasus 1 and Pegasus 2 with an Apple TB2 to TB3 adapter, which should not be a problem.

I tried loading the Pegasus 1 Windows driver, but it did not help.

I will make some inquiries.

We have never tested with any Thunderbolt HBAs.

Upon rereading, I think I see the problem. You may have a USB-C type connector on your computer, but it is not Thunderbolt, so the TB3 to TB2 adapter won't work. It will only work if you connect it to a thunderbolt port. The Pegasus32 will work with a USB connection through a USB-C cable. The Pegasus 1 requires Thunderbolt 1 (or TB2).
