+===== Finding  =====
+An IIO context can have multiple logical devices, and sometimes not all devices will have a specific register interface. To find out which IIO device support register access, try (remember that ''iio_attr'' supports a ''-D'' option to look for debug attributes).
+<xterm>
+# **iio_attr  -u ip:192.168.2.1 -D**
+IIO context has 4 devices:
+	iio:device0, ad9361-phy: found 179 debug attributes
+	iio:device1, xadc: found 0 debug attributes
+	iio:device2, cf-ad9361-dds-core-lpc: found 1 debug attributes
+	iio:device3, cf-ad9361-lpc: found 2 debug attributes
+# **iio_attr  -u ip:192.168.2.1 -D . direct_reg_access**
+dev 'ad9361-phy', debug attr 'direct_reg_access', value :'0x0'
+dev 'cf-ad9361-dds-core-lpc', debug attr 'direct_reg_access', value :'0x90162'
+dev 'cf-ad9361-lpc', debug attr 'direct_reg_access', value :'0x0'
+</xterm>
+From here you can see the three different devices that support the ''iio_reg'' tool.
