Ethos Suite

After connecting my X20S Tx in Bootloader mode to my PC, to interact with the Ethos Suite app, I find that the two Tx drives disconnect periodically and Windows and eventually reports a USB device error.

This is the error I see in Windows Device Manager:

“Windows has stopped this device because it has reported problems. (Code 43)

A request for the USB device descriptor failed.”

Other checks:

• It’s fine if I don’t run the app, ie the two USB drives stay connected and their folders and files can be seen in File Explorer.

• Ethos Suite seems to work successfully in Power Off mode and I successfully installed the latest Bootloader via the DFU option in Ethos Suite (after installing a suitable driver: “Windows Installer reconfigured the product. Product Name: DfuSe v3.0.6. Product Version: 3.0.6. Product Language: 1033. Manufacturer: STMicroelectronics. Reconfiguration success or error status: 1602”)

• I don’t have any problems with other USB devices connected to my PC via the same port.

So this seems to imply a bug in Ethos Suit. Anybody else having issues?

Windows 10 Pro with auto updates (05/06/2022), Version 21H1, OS build 19043.1706
