Bugzilla: 561414 632299 645351 711354 RH-Acked-by: Hans de Goede RH-Acked-by: Jes Sorensen RH-Acked-by: Kevin Wolf It would be nice to have some way to signal our hid devices support remote wakeup. There is a descriptor bit for that of course. Problem with using is one is that older qemu versions used to set the bit even though they did *not* support remote wakeup. Bummer. This patch changes the serial number of our hid devices from "1" to "42" to signal "it is safe to enable remote wakeup". The serial number was choosen because it isn't used for anything and it is available in sysfs so it is easy to match it using udev rules like this: ACTION=="add", SUBSYSTEM=="usb", \ ATTR{product}=="QEMU USB Tablet", ATTR{serial}=="42", \ RUN+="usb_enable_autosuspend %p" Signed-off-by: Gerd Hoffmann (cherry picked from commit 7b074a22dab4bdda9864b933f1bc811a3db42845) --- hw/usb-hid.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) Signed-off-by: Eduardo Habkost --- hw/usb-hid.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/hw/usb-hid.c b/hw/usb-hid.c index 57b49d1..fc7f3e3 100644 --- a/hw/usb-hid.c +++ b/hw/usb-hid.c @@ -100,7 +100,7 @@ static const USBDescStrings desc_strings = { [STR_PRODUCT_MOUSE] = "QEMU USB Mouse", [STR_PRODUCT_TABLET] = "QEMU USB Tablet", [STR_PRODUCT_KEYBOARD] = "QEMU USB Keyboard", - [STR_SERIALNUMBER] = "1", + [STR_SERIALNUMBER] = "42", /* == remote wakeup works */ [STR_CONFIG_MOUSE] = "HID Mouse", [STR_CONFIG_TABLET] = "HID Tablet", [STR_CONFIG_KEYBOARD] = "HID Keyboard", -- 1.7.3.2
