+USB 7-Segment Numeric Display
+Manufactured by Delcom Engineering
+
+Device Information
+------------------
+USB VENDOR_ID   0x0fc5
+USB PRODUCT_ID  0x1227
+Both the 6 character and 8 character displays have PRODUCT_ID,
+and according to Delcom Engineering no queryable information
+can be obtained from the device to tell them apart.
+
+Device Modes
+------------
+By default, the driver assumes the display is only 6 characters
+The mode for 6 characters is:
+        MSB 0x06; LSB 0x3f
+For the 8 character display:
+        MSB 0x08; LSB 0xff
+The device can accept "text" either in raw, hex, or ascii textmode.
+raw controls each segment manually,
+hex expects a value between 0-15 per character,
+ascii expects a value between '0'-'9' and 'A'-'F'.
+The default is ascii.
+
+Device Operation
+----------------
+1.      Turn on the device:
+        echo 1 > /sys/bus/usb/.../powered
+2.      Set the device's mode:
+        echo $mode_msb > /sys/bus/usb/.../mode_msb
+        echo $mode_lsb > /sys/bus/usb/.../mode_lsb
+3.      Set the textmode:
+        echo $textmode > /sys/bus/usb/.../textmode
+4.      set the text (for example):
+        echo "123ABC" > /sys/bus/usb/.../text (ascii)
+        echo "A1B2" > /sys/bus/usb/.../text (ascii)
+        echo -ne "\x01\x02\x03" > /sys/bus/usb/.../text (hex)
+5.      Set the decimal places.
+        The device has either 6 or 8 decimal points.
+        to set the nth decimal place calculate 10 ** n
+        and echo it in to /sys/bus/usb/.../decimals
+        To set multiple decimals points sum up each power.
+        For example, to set the 0th and 3rd decimal place
+        echo 1001 > /sys/bus/usb/.../decimals

 There also are a couple of utility routines drivers can use:

 The conventional usage pattern is that a driver calls
 usb_autopm_get_interface() in its open routine and
 usb_autopm_put_interface() in its close or release routine.  But
