Hi Szymon, Thanks for the feedback. Here are the btmon logs when the device pairs successfully with the SMP Kernel change. The behaviour is similar with Bluez 5.23, that comes default with Debian Jessie. Around 52 seconds mark in the logs, soon after SMP: Pairing Random (0x04) len 16, LE Start Encryption (0x08|0x0019) plen 28 is seen. and then around 55 seconds, SMP: Encryption Information SMP: Master Identification SMP: Identity Address Information SMP: Signing Information messages are seen. Logs below: Software Baseline: Kernel 5.41, Bluez 5.42 FYI: BTMon Logs with the issue is included in my original message http://marc.info/?l=linux-bluetooth&m=147356320523622&w=2 **************** Begin BTMon Logs **************************** Bluez Version 5.41 root@Deb-Jessie:~# btmon Bluetooth monitor ver 5.41 = New Index: 44:1C:A8:6C:8F:5E (Primary,UART,hci0) [hci0] 0.513794 < HCI Command: LE Set Random Address (0x08|0x0005) plen 6 [hci0] 46.048934 Address: 27:5A:29:B2:21:56 (Non-Resolvable)

Hi, Thanks for all the input so far. I found out that the disconnection is coming from Bluetooth SMP in Kernel. After host transmits SMP_CMD_PAIRING_RANDOM, the HID device sends: SMP_CMD_ENCRYPT_INFO SMP_CMD_MASTER_IDENT SMP_CMD_IDENT_ADDR_INFO SMP_CMD_IDENT_INFOCould you get btmon traces from pairing so that we don't need to speculate? In general slave should distribute keys only after master enabled encryption. There is also a small chance of race between encryption event and ACL data on USB transport... I've seen this few times on UPFs but have no idea on how this could be solved without enhancing HCI specification
