     uvisor — USB support for the PalmOS based PDAs


     To compile this driver into the kernel, place the following lines in your kernel
     configuration file:

           device usb
           device ucom
           device uvisor

     Alternatively, to load the driver as a module at boot time, place the following line in



     The uvisor driver provides support for USB based PalmOS PDAs, like Handspring Visor, Palm
     Mxxx series, and Sony Clie.

     The device is accessed through the ucom(4) driver which makes it behave like a tty(4).  The
     device has several ports for different purposes, each of them gets its own ucom(4) device.
     The attach message describes the purpose of each port.

     The usual Pilot tools can be used to access the attached device on the HotSync port.


     The uvisor driver supports the following devices:

        Aceeca Mez1000 RDA
        Handspring Treo
        Handspring Treo 600
        Handspring Visor
        Palm I705
        Palm M125
        Palm M130
        Palm M500
        Palm M505
        Palm M515
        Palm Tungsten T
        Palm Tungsten Z
        Palm Zire
        Palm Zire 31
        Sony Clie 4.0
        Sony Clie 4.1
        Sony Clie 5.0
        Sony Clie PEG-S500C
        Sony Clie NX60
        Sony Clie S360
        Sony Clie TJ37


     /dev/ttyU*       for callin ports
     /dev/ttyU*.lock  corresponding callin initial-state and lock-state devices

     /dev/cuaU*       for callout ports
     /dev/cuaU*.lock  corresponding callout initial-state and lock-state devices


     tty(4), ucom(4), usb(4)


     The uvisor driver was adopted from NetBSD 1.5 in August 2002.  This manual page was adopted
     from NetBSD by Tom Rhodes <> at that time.


     The code to provide multiple ucom(4) instances has not yet been ported from NetBSD.  It is
     unclear whether this driver works in its current state.
