Hi dear, i am working on a project of stm32. Where i configured it as cdc class device...i am able to send and receive the data, but i want it to interrupt the host first and then send the data...i am stuck at that interrupt part. Can you please help me in this.?
This is just going off my head at the moment. but have you reset the interrupt bit. So interrupts have a higher priority over the main loop. If you don't clear that bit in the NVIC it will loop in that interrupt because it has the highest priority.
@brendenadamczak9283 👋 thanks for the reply...I just figured out after couple of days...in STM32 we use USB_LL_Trasmit function....which will send the particular data at particular endpoints. For eg if ox82 then it's Interrupt IN endpoint for the host...so the host will always take this data as Interrupt and can be resolved on priority basis as well
Thank you so much - As usually: Amazing video that Google did not yet recognize. I am looking to reverse engineer Teams Devices (Jabra Headsets) communication and videos about USB and HID are very sparse out here compared to the billions of devices using is 😂 ...
Very interesting. So what do you plan to do with this information? Also note that a semi complicated device like the jabra headsets going to have multiple types of usb descriptions. One for audio and probably one for HID to control muting the audio and stuff like that.
Can you perhaps tell me how to tell the Linux Raspberry Pi Zero system that it should not start a login service when connecting to a USB ACM device (actually a serial USB port of a controller). I only want to access the serial device.
Hi my mobile is bricked and in fastboot/bootloader mode but no pc can detect my device as a device it says device descriptor request failed. I need ur help in configuring the issue thanks for ur valuable information.waiting for ur reply.
Very informative. Thanks for spending time making this content!

You can probably make a rule with udev on Linux
Спасибо! Подписался.

I'm sorry i don't think i know how to help you? I'm not entirely sure where the problem fault lies either?
