Some PCs and Laptops may exhibit poor scan performance with the uScope.


Adjusting Camera SpeedThe uScope transmits image data to the PC over its USB 2.0 connection. By default, camera data consume a very high percentage of the maximum theoretical USB data bandwidth. Some PCs and Laptops are unable to keep up with the high data bandwidth required by the uScope. The result is that image data gets dropped and images must be retransmitted.

Failure to process USB data at full speed has more to do with the USB hardware implementation and less to do with the CPU, RAM, or performance of the PC.


Starting with uScope Navigator V4.3, the camera speed may be adjusted to better match the performance of your PC. Open the Program Options — Advanced Settings tab and drag the Video Speed Setting slider(s) to the desired setting.

Separate controls are available for SD and HD camera modes.

You must recalibrate the cameras after adjusting the camera speed. Refer to the following knowledge base articles for more information:

You may need to disconnect or power-down the uScope before you can access the camera speed controls on Program Options.
