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...).

> https://github.com/texane/stlink This is a port to linux, which is a different story...
