Hi,

In file drivers/hid/hid-input.c, function hidinput_setup_battery() will return during connect a BLE mouse because of filed->usage->hid != HID_DC_BATTERYSTRENGTH. And BLE(ATT) HID doesn't register wakeup source in Linux kernel. 

It will cause BLE HID mouse can't wake DUT from S3. Issue can be reproduced by IBUFFALO BSMBB09DS / Dell WM615 mouse / Microsoft arc touch, these all are BLE mouse. 

static bool hidinput_setup_battery(struct hid_device *dev, unsigned report_type, struct hid_field *field)
{
    struct power_supply_desc *psy_desc = NULL;
    struct power_supply_config psy_cfg = { .drv_data = dev, };
    unsigned quirks;
    s32 min, max;

    if (field->usage->hid != HID_DC_BATTERYSTRENGTH)
        return false;    /* no match */
