Thanks for the confirmation. I see that I actually own the EU variant (I am a German customer):
~ # skuapi -g model_sku
modelNumber = MR8300-EU
I think @Vladdrako is on to something, as the product "codename" (or whatever it is), is actually rogue:
~ # cat /etc/product
rogue
and is definitively referenced in the function start_usb:
service_start ()
{
[ "started" = "`sysevent get ${SERVICE_NAME}-status`" ] && return
SYSCFG_UsbPortCount=`syscfg get UsbPortCount`
[ -z "$SYSCFG_UsbPortCount" ] && return
for i in `seq 1 $SYSCFG_UsbPortCount`
do
start_usb_port $i
done
start_udevd_for_usb
MODULE_PATH=/lib/modules/`uname -r`/
lsmod | grep usbcore 2>&1 > /dev/null
if [ $? -eq 1 ]; then
[ -f $MODULE_PATH/usbcore.ko ] && insmod $MODULE_PATH/usbcore.ko
fi
lsmod | grep xhci_hcd 2>&1 > /dev/null
if [ $? -eq 1 ]; then
[ -f $MODULE_PATH/xhci-hcd.ko ] && insmod $MODULE_PATH/xhci-hcd.ko
fi
lsmod | grep ehci_hcd 2>&1 > /dev/null
if [ $? -eq 1 ]; then
[ -f $MODULE_PATH/ehci-hcd.ko ] && insmod $MODULE_PATH/ehci-hcd.ko
fi
lsmod | grep ohci_hcd 2>&1 > /dev/null
if [ $? -eq 1 ]; then
[ -f $MODULE_PATH/ohci-hcd.ko ] && insmod $MODULE_PATH/ohci-hcd.ko
fi
lsmod | grep uhci_hcd 2>&1 > /dev/null
if [ $? -eq 1 ]; then
[ -f $MODULE_PATH/uhci-hcd.ko ] && insmod $MODULE_PATH/uhci-hcd.ko
fi
lsmod | grep usb_libusual 2>&1 > /dev/null
if [ $? -eq 1 ]; then
[ -f $MODULE_PATH/usb-libusual.ko ] && insmod $MODULE_PATH/usb-libusual.ko
fi
sleep 30
MODEL_NAME=`syscfg get device::model_base`
if [ -z "$MODEL_NAME" ] ; then
MODEL_NAME=`syscfg get device::modelNumber`
MODEL_NAME=${MODEL_NAME%-*}
fi
if [ "EA9200" = "$MODEL_NAME" ] ; then
ulog usb service "here,enable usb port again"
echo "low" > /proc/bdutil/usbhub
fi
if [ "lion" = "`cat /etc/product`" -o "rogue" = "`cat /etc/product`" ]; then
lion_usb_power_reset
fi
sysevent set ${SERVICE_NAME}-status started
ulog usb service "$PID : udevadm trigger "
/sbin/udevadm trigger --subsystem-match=usb --attr-match=bInterfaceClass=07 --action=add
/sbin/udevadm trigger --subsystem-match=usb --attr-match=bInterfaceClass=08 --action=add
/sbin/udevadm trigger --subsystem-match=block --action=add
}
which then calls the function lion_usb_power_reset:
lion_usb_power_reset ()
{
echo "===> RESET LION usb power" > /dev/console
echo "68" > /sys/class/gpio/export # gpio.68 (USB_PWR_EN)
echo "out" >/sys/class/gpio/gpio68/direction
echo "1" >/sys/class/gpio/gpio68/value # pull High, then pull Low (it's active Low)
sleep 2
echo "0" >/sys/class/gpio/gpio68/value
}
But this is already done early at boot, not while mounting any USB drive, as far as I can judge (from the boot log),
Below just some random snippets from the boot log, which thought might be interesting:
[ 1.301607] msm_serial_hsl_init: driver initialized
[ 1.306565] uart_tx_gpio is not available
[ 1.309993] uart_rx_gpio is not available

[ 2.545803] input: gpio_keys.9 as /devices/soc.1/gpio_keys.9/input/input0
I updated the firmware version to see if there are some relevant changes I could spot (spoiler: I couldn't)
