Hello List I am studying to start multiple ccch_scan simultaneously,but I meet some problem. I do as following: 1.I have two C118, caonnect them to the same computer 2.dump the sniffer rom ./osmocon -p /dev/ttyUSB0 -s /tmp/osmocom_l2_0 -m c123xor ./sniffer.bin ./osmocon -p /dev/ttyUSB1 -s /tmp/osmocom_l2_1 -m c123xor ./sniffer.bin 3.start the ccch_scan of burst_ind ./ccch_scan -s /tmp/osmocom_l2_0 -a *** -i 127.0.0.1 ./ccch_scan -s /tmp/osmocom_l2_0 -a *** -i 127.0.0.1

but there is always one ccch_scan give the following output after some time. <0001> app_ccch_scan.c:296 GSM48 IMM ASS (ra=0x99, chan_nr=0x40, HSN=47, MAIO=4, TS=0, SS=0, TSC=2) Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI Unknown SI I think it is an syn problem, maybe caused by the usb bus. does anyone have the idea?

thanks!
