nrf 52840 usb max speed configuration

[quae]

hello i'm using nrf52840 dk board for communication with windows pc.

in nrf 52840 datasheet usb max speed is 12Mbps but my project based on "usb_cdc_acm" usb speed is 4Mbps. i want to increase usb speed to 8Mbps. Is there another way to satisfy 8Mbps?

thank you.

Probably not.

Its difficult to read this from the PS, but the USB peripheral does not have double buffered endpoints for USB bulk transfers.

That lowers the achiveable transfer rates to somewhere around 300KB/sec.
