W1-master-gpio

Hallo! I've got problem with OpenWrt on Omega2 Onion and reading one wire ID.
So many issues about connecting temp sensor ds1820 for example, but problem that i can't resolve is:
timeout for read ibutton (ds2401 for example) is 10 seconds/ but 1 or 2 seconds is normal time period to read. i can't transmit options then insmod w1 module and time is 5-10 seconds for reading ID dallas is tooo long/ please, is anybody knows how to make this faster?

cat /sys/devices/w1_bus_master1/w1_master_slave_count i wait here/
