NRF52840 USB stucks after while

[martin.richter.supervag]

Hi,

i am checking NRF52840 for USB behaviour. I'm using example usbd_cdc_acm. But USB receiving stucks after few bytes (between 0 and 50) and does not receives nothing more.

I corrected the buffer size as recommended in devzone.nordicsemi.com/.../

Hi,

Please provide some more information.

• What SDK version are you using?

• What version of the nRF52840 PDK are you using? It should be printed below PCA10056 on the sticker on the kit.

• Do you have more than 1 nRF52840-PDK you can test with?

• Do you have custom boards using "engineer samples" ?

If you are using engineer samples:

• How many of these custom boards with engineer samples do you have ?
• What is the build code on the engineer samples?
