Hi,
I am working on a battery powered device that collects data, save it to files and go to sleep, when it is not connected to a laptop via USB. When connected, the device just become a "usb sd card reader" that shows the files, the sensors are disabled and the device never goes to sleep. I have based my application on the MSC sample, I can read the SD when I connect to a PC with no issue. My problem is when not connected to USB, on a "fresh" boot I can save data files fine but after waking up from sleep I get an initialisation error from usb_msc and a system reset, the next boot works fine (data can be written on sd) until the mcu is sent to sleep again and the loop repeats. It seems that I need to disable/uninit the mass storage before going to sleep somehow. However wouldn't CONFIG_USB_MASS_STORAGE=y keep the mass storage enabled, is there a way to only have Mass storage activated when connected with USB?
I found this post but it is using a older ncs sdk and this post that suggest to change the USB descriptors at runtime but I couldn't figure out how to edit the descriptors at runtime.
I am using nrf-sdk 2.6.1 on VS code, a nrf5340 custom PCB.
Any help would be greatly appreciated.
