I am doing a Nordic project, that need to be a USB host. May I know how to make nRF52840 to be a USB host ?

I have found that the nRF52840 is not capable of being a USB host, it's peripheral only. I've concluded that from this devzone post and this infocenter entry.
You can use a microcontroller with USB host functionality and another communication protocol compatible with the nRF52840 or a USB bridge IC. I'm doing the same thing at the moment using an SPI to USB bridge.
guys do you have tried the Vinculum-II? I also want to connect a nRF5840 to a CDC Modem using AT commands a give it cellular functionality. at the moment no luck to make work the Vinculum II
I have not.
I am using a MAX3421E, this does not have a programmable microcontroller though.
Thanks @KevinL I am going to give a look to that one :)
Hello KevinL,
Can you help us understand the settings that were done for MAX3421E to be configured for USB host? Does the SPI on Nordic have to configure the MAX3421E chip ? We are using the same but facing issues in interfacing it to Nordic. Thanks for the help.
