Małe k. Autokorekta robi swoje.
próbowałem dymyśliłem się 
ale coś marudzi

małe usb ok 
poszłoooo
Co tu może być źle?

I nie działa mi na /dev/ttyRS485 Co robię Cezary nie tak?
Zrob sobie mały debug przez logger "$coś tam" co drugą linię i zobacz jakie zmienne przychodzą i co on widzi.
Dla potomnych działa ten oto skrypcik znaleziony na openwrt.org:
cat << "EOF" > /etc/hotplug.d/usb/20-cp210x
CP210_PRODID='10c4/ea60/100'
SYMLINK="my_link"
set -eu
if [ "${DEVTYPE:-}" = 'usb_interface' ] && \
[ "${PRODUCT:-}" = "${CP210_PRODID}" ]; then
if [ "${ACTION:-}" = 'bind' ]; then
if [ -L "/dev/${SYMLINK}" ]; then
logger -t hotplug "Symlink '/dev/${SYMLINK}' already exists"
exit 0
fi
DEVICE_NAME="$(find /sys${DEVPATH:-} -maxdepth 1 -type d -iname 'ttyUSB*' -exec basename {} \;)"
if [ -z "${DEVICE_NAME}" ]; then
logger -t hotplug 'Warning: DEVICE_NAME is empty'
exit 0
fi
logger -t hotplug "Device name of cp210 is '${DEVICE_NAME}'"
ln -s "/dev/${DEVICE_NAME}" "/dev/${SYMLINK}"
logger -t hotplug "Symlink from '/dev/${DEVICE_NAME}' to '/dev/${SYMLINK}' created"
fi
if [ "${ACTION:-}" = 'unbind' ]; then
rm "/dev/${SYMLINK}"
logger -t hotplug "Symlink '/dev/${SYMLINK}' removed"
fi
fi
EOF
W przypadku mojego konwertera PRODID='403/6001/600'
Działa zarówno podczas startu systemu jak i po załadowaniu. Można wsadzać i wyjmować ile się chce razy a i tak kojarzy link tak jak trzeba
Próbuje zrobić aliasy do modemu EC200 w sensie, że ponazywać sobie /dev/ttyUSB1 np jako "odczyt3ginfo" , /dev/ttyUSB2 np. jako "data" itp. Na openwrt przedstawia się on tak:

Ale jak teraz wyczaić który z tych ttyUSB* jaką ma nazwę DEVICENAME. Jest gdzieś w systemie to odnalezienia?
W /sys poszukaj.
Nie mogę tego jakoś odnaleźć. Masz może jakiś modem i router u siebie żeby sprawdzić na owrt gdzie to leży?
Ok znalazłem polecenie:

Ale lipa bo jak wyjmę przed startem konwerter rs485 to już ostatni z modułów modemu jest nie ttyUSB8 a ttyUSB7 i jego nazwa to 2-1.2:1.7 a nie 2-1.2:1.8 wiec się zmienia nie da się tego od tej danej uzależnić ech...
No zmienia się. Wiec albo bazujesz na tym że zawsze wkładasz do tego samego portu albo na podstawie serial number albo czegoś innego.
Własnie tamte pozostałe interfejsy nie mają serial numebr albo ja nie wiem jak to sprawdzić. Robiłem Twoim skryptem i w /tmp jest tylko:
DEVNAME=bus/usb/002/006

Nie dostarcza ci on seriala.
