There have been reported cases where a user lost control of their computer's cursor when a ProComp amplifier was connected to the computer. This can be observed as the onscreen cursor pulling continuously to one location on the screen, or additionally right- or left- clicking on a continual basis. The user is able to still influence the cursor with their trackpad or an external mouse, but the onscreen cursor moves too rapidly to overcome. This issue was reproduced and confirmed through internal testing and appears related to driver issues brought on by Windows updated, not an issue with the EEGer4 software or the amplifier being used.
We have included instructions below to attempt to troubleshoot the issue. If you have any issues during the process, feel free to contact us and we would be happy to help!
Without the amplifier connected, you should be able to control your mouse normally. To prepare for later steps once we connect the amplifier, please follow the steps below:
We suspect that the reason you are unable to control your cursor is because Windows is interpreting the signal being sent from the amplifier to the computer as a mouse. If this is the case, we should expect a new device to show up under Mice and other pointing devices once the amplifier is connected. Thankfully, we should be able to disable Windows from using the signal from your amplifier as a mouse.
If you are unable to right or left click at this stage, press the Ctrl+Alt+Delete keys on your keyboard at the same time. This should open up a new screen allowing you to change users, open the task manager, and sign out. You will want to press cancel from the list to return back to the Device Manager. For whatever reason, this refreshes Windows to allow you to click normally with the trackpad.
Please ensure you do not accidentally disable your trackpad in the Device Manager, as this will make reenabling the trackpad difficult without use of an external mouse.
If you are still experiencing issues at this stage or were unable to follow the steps detailed above, please let us know! We can provide additional troubleshooting by email or if you would like to set up a remote tech appointment to connect directly to your computer and provide troubleshooting from there.
