Hello,
i use the Modem (Home Page Obsolete products) Fastrack M1306B.
Unfortunately i lost the USB driver for that and this isn’t to download in your Home page.
Maybe the question relates to a 3rd party driver for a USB to RS232 cable converter. If it does, that’s not an accessory provided by Wavecom so you’d need to get the driver from the USB2UART converter supplier web site or buy a new converter as they’re dirt cheap!
