I’m confused on why you quoted me, when I was talking to PaRam about the USB connection problem. RamCares could probably assist you also.My "issue" was clear early in the morning. Especially if my windows were cracked and humidity/moisture got it. The leather would swell and had clear bumps all over the area. If the windows were closed the sunlight would tighten the leather like new. However you could tap on it and feel that drum sound, which was clear that the Leather was not glued down.
