Hi
Does anybody know how to debug hotplug script without hotplugging the device. I am try to debug usbserial device ti_usb_3410_5052.hotplug device after downloading firmware. I see that the hotplug fails error -5. I need to see what is going on after downloading the firmware. How to debug the script.I know /sbin/hotplug debug=1, shows some info, but not completely.
The script is below and copied to /etc/udev/hotplug.d. My kernel is linux 2.6.26 on rehat enterprise linux4.
BOOT_CONFIG=1
ACTIVE_CONFIG=2
if [[ "$ACTION" != "add" ]]
then
exit
fi
CONFIG_PATH=/sys${DEVPATH%/?*}/bConfigurationValue
if [[ 0`cat $CONFIG_PATH` -ne $BOOT_CONFIG ]]
then
exit
fi
PRODUCT=${PRODUCT%/?*} # delete version
VENDOR_ID=`printf "%d" 0x${PRODUCT%/?*}`
PRODUCT_ID=`printf "%d" 0x${PRODUCT#*?/}`
PARAM_PATH=/sys/module/ti_usb_3410_5052/parameters
function scan() {
s=$1
shift
for i
do
if [[ $s -eq $i ]]
then
return 0
fi
done
return 1
}
IFS=$IFS,
if (scan $VENDOR_ID 1105 1760 `cat $PARAM_PATH/vendor_3410` &&
scan $PRODUCT_ID 13328 61704 61705 61712 61713 61714 `cat $PARAM_PATH/product_3410`) ||
(scan $VENDOR_ID 1105 `cat $PARAM_PATH/vendor_5052` &&
scan $PRODUCT_ID 20562 20818 20570 20575 `cat $PARAM_PATH/product_5052`)
then
echo $ACTIVE_CONFIG > $CONFIG_PATH
fi
Thanks
