Hi,
I have implemented USB audio (on my project) which is based on the memsmic1 example project.
The MCU i am using is STM32L496x, under keil IDE.
the device is recogined by window as audio device but, when i disconnect and reconnect again, I am having an Error Code 43,because a request for the USB device descriptor was failed.
did someone had this problem before? is there a way to solve it beside shutdown the device
?
Thanks, Avi

Hello,
Check the state of the DP and DM signal lines.
May be you have swapped USB D+/D- lines.
Thanks
Imen

Hello,
but it's not happening in HID or MSD profile.
