Dear Bluetooth community, You are committing version after version and have time to add new Features and the core stack have a major bug (software Caused connection abort) that i Have reported on the 7th of may the problem seems to be either in the usb part of the Kernel or the bluez stack, i am no kernel engineer so i came directly to you for reporting This problem and my requests to look into this problem are just ignored. this is a blocker Issue that would prevent and discourage any one from developing application that rely on Bluez sco capabilities, since during transmission the above mentioned error just occurs. I hope that my voice is heared and i would get a reply from the bluez community.
