Similar to Nirmal's DVD writer USB question, you need to first see
whether your system is aware of the device's presence at all.

Run dmesg after plugging the device is connected and see if the kernel
registers any message about the device. If it doesn't, then there is a
lower level problem which we'll have to figure out.  If it does, that
message might give you some clue about what's going on.

Is there a reason you picked ttyUSB1?  Have you tried ttyUSB0, etc.?

Also, which kernel are you using?  You will likely need at least 2.4.18,
but I would recommend 2.4.23.

You can get your kernel version by typing uname -a.

Also, I think you the usbserial driver as well for the /dev/ttyUSB*
devices to work.

You may want to try usb-ohci rather than usb-uhci.

Those are some hints to get started. Let us know if you solve it...
