Thanks for the quick reply, Dave. Meanwhile I finally discovered a more [detailed description](https://www.st.com/resource/en/application_note/an5731-stm32cubemx-and-stm32cubeide-threadsafe-solution-stmicroelectronics.pdf) of what they are actually doing. The document does not specify to which version of STM32CubeIDE...

Upon closer inspection of their code and Application Note, their variants #4 and #5 seem to roughly correspond to the behavior one gets from Dave's code with MALLOCS_INSIDE_ISRs either defined...

I cannot comment on previous or current USB drivers, as I only ever used I2C, SPI, UART, GPIO HAL-drivers together with your MALLOCS_INSIDE_ISR-undefined variant, but I might now go ahead...

Well, for me and the iOS/swift code that I am currently working on, the renewal is still working without explicit such Cookie-Headers. Not sure why, because when I use curl...
