Problems with Prolific driver – Solution.

This entry was posted on Dec 08 2010
We are currently working on our Bachelor thesis where we are developing a TUI module for task status visualization. During this process we stumbled over a annoying problem with the Prolfic / LogiLink USB to serial (RS232) adapter which we wasn’t able to use on several Windows 7 computers resulting in the following error in device manager: “This device cannot start code 10 error”
After several hours of googling we found that the only driver working on W7 was the Windows Vista driver (v2.30) which can be downloaded from
We would like to link to cooldriver’s previous page with links to the driver, but they removed this, forcing us to link directly to the zip file.
Hope this saves all of you for a lot of wasted time 🙂
Update: Thanks for all the comments on this post. The driver has now proven to also work for Dynex DX-UBDB

    Windows tries to check online for new drivers, cancel the process and choose from installed drivers.
