USB device and licenses

Hello!

 I'm trying to get my STM32L USB device to communicate with PC. Actually i'm stuck at just building the project files for ported (STM32L) HID example project and I've come across a problem already. I use MDK-ARM and the error message is:

.\Flash\HID.axf: Error: L9937E: RL-ARM is not allowed with this license

 I have MDK-ARM Standard license. So, does that mean I can't use USB device if I don't have pro license? I don't use RTX (BTW: it is possible to use USBd without RTOS/RTX, right?)

 Thanks for answers.

You'd need to discuss this with Keil support. Otherwise you'll need to use ST's firmware library examples.
