"unknown main tag item 0x0" comes from the HID layer, it has nothing to do with Bluetooth or connection stability. It's usually a stray NUL character at the end of the HID descriptor which the kernel safely ignores but still logs. In my own driver development (xpadneo), I just shorten the HID descriptor by one byte if it ends with NUL because the devices I work with are known to NUL-terminate their HID descriptors.
Maybe the kernel should do the same: If the last HID descriptor byte is a NUL-byte, it should simply shorten the HID descriptor by one byte, essentially cutting the offending byte off, and the message would be gone. Other than a log message, it has no consequences in the kernel, it comes from a completely different layer that's not related to Bluetooth at all. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1385113 Title: hid-generic 0005:099A:0500.0001: unknown main item tag 0x0 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1385113/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
