Hi Amanda,

Our usecase is, usb seems to be using DMA, I'm sending fixed number(255) of bytes from PC to NRF. What I want is, incase the the host pc failed to send 255 bytes, let's say only manage to send 250, a timeout will trigger and will reset the usb_cdc_read. howeverer, calling another usb_cdc_read doesn't seem to work.

Thanks,

Miguel

Hi,

Could you elaborate on your need? Maybe present to us your use case? We already have non-blocking API in CDC ACM (app_usbd_cdc_acm_read_any and app_usbd_cdc_acm_rx_size functions) that should do what you need. You wouldn't need to use the blocking API then cancel it.
