cannot syncronize palm with jpilot

[Igor Anikeev]

I used to do it by including modules usbserial,visor, and usb-storage 
(to get use of my memorystick) - now it doesn't work.

I tried to include the following to modprobe.conf:

install visor /sbin/modprobe --ignore-install usbserial
install usb-storage /sbin/modprobe --ignore-install usb-storage; 
/sbin/modprobe

Doesn't work either. On the other hand I also have an IrDA USB adapter 
attached and lsusb says:

Bus 002 Device 001: ID 0000:0000
Bus 001 Device 003: ID 066f:4200 SigmaTel, Inc. STIr4200 IrDA Bridge
Bus 001 Device 001: ID 0000:0000

Does anyone have any ideas on how to resolve it and what (/dev/ttyUSB0 
or /devttyUSB1) I should map as /dev/pilot?

Igor
