+## Probing for Unrecognized Devices
+
+Sometimes you may need to do a little extra work to support devices which
+usb-serial-for-android doesn't [yet] know about -- but which you know to be
+compatible with one of the built-in drivers.  This may be the case for a brand
+new device or for one using a custom VID/PID pair.
+
+UsbSerialProber is a class to help you find and instantiate compatible
+UsbSerialDrivers from the tree of connected UsbDevices.  Normally, you will use
+the default prober returned by ``UsbSerialProber.getDefaultProber()``, which
+uses the built-in list of well-known VIDs and PIDs that are supported by our
+drivers.
+
+To use your own set of rules, create and use a custom prober:
+
+```java
+// Probe for our custom CDC devices, which use VID 0x1234
+// and PIDS 0x0001 and 0x0002.
+ProbeTable customTable = new ProbeTable();
+probeTable.addProduct(0x1234, 0x0001, CdcAcmSerialDriver.class);
+probeTable.addProduct(0x1234, 0x0002, CdcAcmSerialDriver.class);
+
+UsbSerialProber prober = new UsbSerialProber(customTable);
+List<UsbSerialDriver> drivers = prober.findAllDrivers(usbManager);
+// ...
+```
+
+Of course, nothing requires you to use UsbSerialProber at all: you can
+instantiate driver classes directly if you know what you're doing; just supply
+a compatible UsbDevice.
