+This serial driver currently only works with the Belkin and Peracom USB 
+Serial devices. It should also work for the Etek converter, but I do 
+not know the vendor id and device id of that device (if anyone does, 
+please let me know.)
+
+If your device is not compatible with the above models, you can try
+out the "generic" interface. This interface does not provide any type
+of control messages sent to the device, and does not support any kind
+of device flow control. All that is required of your device is that
+it has at least one bulk in endpoint, or one bulk out endpoint.
+To enable the driver to recognize your device, build the driver as
+a module and load it by the following invocation:
+	insmod usb-serial.o vendor=0x#### product=0x####
+where the #### is replaced with the hex representation of your device's
+vendor id and product id.
+
+The driver can handle enumerating the device, and sending and receiving
+data from the converter. However, since I do not have a spec for the Belkin,
+Peracom, and eTek devices, and the raw dumps from the Win98 driver are 
+confusing, and eTek keeps giving me the run around, no control signals are 
+currently handled, and the data will most likely come through on a baud
+rate that you are not expecting. So if you have these devices, do not 
+expect the correct data to show up at either end. 
+
+The major number that the driver uses is 188 so to use the driver, create
+the following nodes:
+mknod /dev/ttyUSB0 c 188 0
+mknod /dev/ttyUSB1 c 188 1
+mknod /dev/ttyUSB2 c 188 2
+mknod /dev/ttyUSB3 c 188 3
+
+then plug in a device and use your friendly terminal program to see what
+happens.
+
+If anyone has any problems getting the device to enumerate, or data to 
+flow through it, please contact me.
