- * E: Error code. I'm not sure about these, but gpm's sources,
- * which support this mouse, too, tell about them:
- * E = [0x00 .. 0x1f]: no error, byte #3 is button state
- * E = 0x3d: button error, byte #3 tells which one.
- * E = <else>: other error
+ * E: Error code. If it's in the range of 0x00..0x1f, only some
+ * minor problem occured. Errors >= 0x20 are considered bad
+ * and the device may not work properly...
