This seems to be a query for "channel group specific device options", which only mixed signal devices and few special cases (temperature and humidity, channel dependent features) supoprt. The fx2lafw(4) driver appears to be "logic analyzers exclusively", so CG specific options shall not apply. So the simple approach to just silence the sr_err() message could do: src/hardware/fx2lafw/api.c:config_list() case SR_CONF_DEVICE_OPTIONS: if (cg) return SR_ERR_NA; return STD_CONFIG_LIST(...);
