[clug] usb/serial help required

[David Murn]

Hello Eyal,

I have a few USB devices that I use directly within windows through
vmware (laser printer and GPS on occasion).  Within vmware workstation,
you can configure the host to share certain USB deveices with the guest
(windows) system.  Then your windows guest will simply pop up a balloon
saying a usb device is plugged in, and youll need your original UPS
windows software drivers, exactly as if it was running natively.

Also, I suggest if the device really is a usb/serial converter, that it
will be using a prolific 2303 chip.  Try modprobe pl2303.  My GPS uses a
usb/serial converter cable which then appears in Linux as /dev/ttyUSBn.

Hope some of this might be of assistance.

David
