Comment:

commands to execute were commented out, output is left uncommented. This was totally backwards, I corrected it so the commands can be coppied and pasted

 You must determine the SPI bus at runtime which can be done via:
 {{{#!bash
-# BUSNO=$(for i in $(ls /sys/class/spi_master/); do if [ "$(basename $(readlink /sys/class/spi_master/$i/device))" == "spi-ft232h.0" ]; then echo $i | sed 's/[^0-9]*//g'; fi; done)
-# echo $BUSNO
+BUSNO=$(for i in $(ls /sys/class/spi_master/); do if [ "$(basename $(readlink /sys/class/spi_master/$i/device))" == "spi-ft232h.0" ]; then echo $i | sed 's/[^0-9]*//g'; fi; done)
+echo $BUSNO
 }}}
 
 Now the module can be loaded as such:
 {{{#!bash
-# modprobe nrc fw_name=nrc7292_cspi.bin bd_name=nrc7292_bd.dat spi_bus_num=$BUSNO spi_polling_interval=5 hifspeed=30000000
+modprobe nrc fw_name=nrc7292_cspi.bin bd_name=nrc7292_bd.dat spi_bus_num=$BUSNO spi_polling_interval=5 hifspeed=30000000
 }}}
 
 After several seconds due to the timing of firmware loading you should see a new wlan device under /sys/class/net. To find the correct wlan interface that is bound to the NRC7292 driver:
 {{{#!bash
-# WLAN="$(for i in $(ls -d /sys/class/net/wlan* 2>/dev/null); do if [ "$(basename $(readlink $i/device))" == "nrc80211" ]; then basename $i; fi; done)"
-# echo $WLAN
+WLAN="$(for i in $(ls -d /sys/class/net/wlan* 2>/dev/null); do if [ "$(basename $(readlink $i/device))" == "nrc80211" ]; then basename $i; fi; done)"
+echo $WLAN
 wlan0
