We are using STMFlashLoader on a Windows 7 machine to download firmware to an STM8 device. We are migrating from XP. What is happening is that download often just hangs. And when that happens the port being used is hung and all the other USB ports on the machine act weird as well (eg, discovery stops). Using an HP EliteBook. There is no way to recover I've found short of rebooting the machine. Our application is to provision devices in a factory environment and this behavior (download hanging, USB ports not working) is a blocker problem. Has anybody else seen this behavior? Any idea what is causing it and how to overcome it?
