did a google search none of the links worked.

I installed st-link_v2_usbdriver.zip, ST-LINK_Utility_V2.2Patchv10.zip

I searched my computer for STLinkUSBDriver.dll and could not find it.

I was able to install the STLink dongle that shows up in my device list.

    In general, I'm aware of two problems that might cause your trouble.

    One is a 32 Bit / 64 Bit driver issue.

    The other, more probable, is ''Addon'' software that some PC/Notebook distributors install.

    If your host is a notebook, and has lots of preinstalled software, try to deinstall suspicious stuff.

    If you want to dig in, I could recommend the ProcessExplorer and DependencyWalker.

    it is a 32 bit Net book with only 50% real memory allocated.

    Win7 starter.

    I have drivers for Ardrino, Maple installed and working.

    when I plug in the STM32F4 Discovery I see the ST Link as a hub.

    the directory STMicroelectronics\st_toolset  was added but no files.

    I did a file search and did not find the file

    STLinkUSBDriver.dll

    anywhere on the system.

    is there a place I can get the STLinkUSBDriver.dll ?

    As far as i know, it usually comes with tool suites that support the stm32f4.

    Atollic and Keil MDK have their versions copied somewhere intheir folder subtree.

    Crossworks wants you to set a link to an existing DLL, at least under Windows. The linux version supports stlink V2 out of the box.

    If the STLink utility does not come with this DLL, I could only suggest download and install one of the tools mentioned above (and not forgetting IAR...).

    This is a port to linux, which is a different story...

    only at the linking level, I did a diff of code and just show the August date an RC1, otherwise the same. I did not check the make files.
