Hi, Just upgraded the Keil 5.10 to 5.11 to have STM32L0 support.
When trying to debug my application I get: "st-link usb communication error" and debug fails.
I have no problem connecting to my board using ST-Link Utility.
The 5.10 works fine - no issues with connecting to the ST-link.
I use the latest ST-link drivers and firmware (STLinkUSBDriver.dll v4.3.3.0, ST-LINK Firmware version : V2J21M5)

Anyone can send in bug reports. A bug in an evaluation version will be just as important to close since 1) People hurt by it will think twice about buying a commercial license. 2) The bug is likely to also exist in the commercial editions.
The only problem is that the support is likely to receive a huge number of user-error reports - and much more such reports from students using the evaluation version and lacking experience with programming.
Thank you for your suggestions.
I submitted the issue as a bug report. Bogdan
