Hello Alan, Thanks for your reply. I have uploaded the 2 logs from usbmon: Kernel 33: https://bugzilla.kernel.org/attachment.cgi?id=3D303806 Kernel 37: https://bugzilla.kernel.org/attachment.cgi?id=3D303805 If you need more information I am all ears. Thanks. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
