Hi,
If you have a recent kernel, the USB FET tools should just work.
However, some distros don't have hotplug set up properly. You may need
something like a file called /etc/hotplug/usb/ti_usb_3410_5052 containing
#!/bin/bash
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 `cat $PARAM_PATH/vendor_3410` && scan
$PRODUCT_ID 13328 62512 `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
