Some laptops are unstable with Impera/Neets keypad controllers using USB

We have received some reports from installers that they are experiencing an unstable connection to their keypad controllers.

Error description

1. It takes a long time to detect the Impera controller when connected via USB (around 20-25 seconds)
2. Unstable communication ("Get information" and project upload fails or takes a long time)

We have mostly seen it being an issue on Echo, Echo Plus, Oscar and Bravo. 

We have experienced issues with the below models, but there might be others

Lenovo ThinkPad T15

Lenovo ThinkPad E15

Lenovo ThinkBook 15 G2 ITL

Asus TUF Gaming FX504G

Please write to Biamp technical support with your laptop make and model number if you experience the above mentioned issues as well.


Use an external USB hub instead of the USB ports in the laptop.


We have contacted Lenovo support regarding this issue, but it seems to be an issue with the newest Intel SoC.
