Canon does not cease to amaze me. Today I’ve got not very pleasant surprise with it. When I tried to connect my Canon PowerShot S90 camera to my computer via USB, on the small screen displays the error message: «Communication error». Any attempts to establish communication with the camera via other USB ports and even through another computer were unsuccessful. I even thought that the issue in the USB port of my camera. However, everything was easier.
Empirically, I found out that for some inexplicable reason, the camera may not be synchronized if the number of images on the card more than 3059! I deleted some photos, and communications restored.
