This is a note to let you know that I have just added a patch titled HID: logitech-dj: do not directly call to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From af00ab2625ef7dfcb6401afeb464a50bcb79b802 Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires <benjamin.tissoires@redhat.com> Date: Tue, 5 Mar 2013 17:09:00 +0100 Subject: [PATCH] HID: logitech-dj: do not directly call hid_output_raw_report() during probe commit dcd9006b1b053c7b1cebe81333261d4fd492ffeb upstream. hid_output_raw_report() makes a direct call to usb_control_msg(). However, some USB3 boards have shown that the usb device is not ready during the .probe(). This blocks the entire usb device, and the paired mice, keyboards are not functional. The dmesg output is the following: [ 11.912287] logitech-djreceiver 0003:046D:C52B.0003: hiddev0,hidraw0: USB HID v1.11 Device [Logitech USB Receiver] on usb-0000:00:14.0-2/input2 [ 11.912537] logitech-djreceiver 0003:046D:C52B.0003: logi_dj_probe:logi_dj_recv_query_paired_devices error:-32 [ 11.912636] logitech-djreceiver: probe of 0003:046D:C52B.0003 failed with error -32 Relying on the scheduled call to usbhid_submit_report() fixes the problem. related bugs: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1072082 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1039143 https://bugzilla.redhat.com/show_bug.cgi?id=840391 https://bugzilla.kernel.org/show_bug.cgi?id=49781 Reported-and-tested-by: Bob Bowles <bobjohnbowles@gmail.com> Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Luis Henriques <luis.henriques@canonical.com> --- drivers/hid/hid-logitech-dj.c | 22 ++++++++++++++-------- 1 file changed, 14 insertions(+), 8 deletions(-) -- 1.8.1.2
