Titan T3, around three month old, and suddenly today I cannot have it connected to Titan GO.
When plugged in in a Windows 10 laptop (which is used regularly with that T3) windows says USB device not recognized and under device manager it says: "Unknown USB Device (Device Description Request Failed).
I have tried it on other PC, reinstalled Titan go, new USB cable etc.....but same every time.
Strange is, that when open in Authenticator it reads that T3 is connected and serial number of device.....so Authenticator recognize console, but when software is launched it says it cannot connect to hardware.
I have tried in USB Exper Console to reinstall drivers, but it also do not detect T3.
Also, for the test, when I T1, software works ok, Authenticator also recognize T1.....so on both pc T1 is working good, but T3 cannot be recognize.
Either maybe there is hardware or USB port failure in T3, but strange is that Authenticator does recognize it.....or there is some workaround with it, if anyone experience this issue?
Thanks!

The Device Description Request Failed message indicates a fairly low level error with the connection. When you plug in a USB device there is an exchange where the computer will ask the device to identify itself, it will then use this to work out which driver to use and how to communicate with it, however if that first exchange doesn't get through it won't even get as far as drivers.

Possible causes include the USB cable or USB ports being faulty. In the case of the T3 if the USB port is not able to provide the required power, the device might not be able to initialise properly. Sometimes even on the same computer different USB ports might be able to provide different amounts of power and a laptop running on battery might reduce the power allowed for USB devices. Using a powered USB hub is a potential way of ensuring there is enough power available. You could also check that Windows is not set to some sort of power saving mode and USB selective suspend is turned off.

Regarding Authenticator, the T3 is actually made up of multiple devices which are connected internally so it is possible that one might have managed to work when the others have not, especially if there is not enough power to go around.

If you continue to have issues I would suggest that you open a support ticket for further assistance.
