If you are looking for SB4200 modem driver in Motorola website, you will not be able to find the driver download link because Motorola has not listed or removed the link for SB4200 usb driver.

As of time of writing, the only available USB drivers for download are for SURFboard® Cable Modem SB5102/SB5101/SB5120, Cable Modem SB6100J, Wireless Cable Modem Gateway SBG900 and Netopia® 2210-02 ADSL2+ Residential Gateway.

I think these models are never thus Motorola make the driver available for download on its website. As for older models, such as SB4200, the download links are taken down.

As usually manufacturers do not actually delete the existing driver file, they only taken down the link, thus with a little guess work, I am able to find the readme.txt for SB4200.

From the readme file, the following information is gathered and since the readme says that SB5101 driver file ( is the one same with SB4200 ( , and SB5101 driver is listed on the driver download. So we have found the driver for SB4200!
