nrf52840 PDK USB HID examples not working on Linux Host

[thomas malcher]

Hi,

I have a problem with the usb HID examples in sdk v15.0 on a nrf52840 Preview DK.
I cannot get them working together with a Linux or WindowsCE based USB Host, with Windows10 Host everything works as expected. The CDC example works on Linux and Win.

For a Linux host I did some investigation with wireshark. Everything looks good until HID Get_Report request. Then the nf52840 does not respond with the Report Descriptor, it does so with a Win10 Host.

Could this be a problem of the HW (Peview DK v0.9.2), or does anybody have any idea what I'm doing wrong?

Thanks, thomas

Hi,

 

I recommend that you use the latest version of the nRF52840 to develop on.

v0.9.x has engineering A mounted on it, and this one has many erratas on the USBD peripheral and workarounds for this has been removed from SDK v15. 

 

Best regards,

Håkon

Yes that was the problem. The examples from SDK v14.2 work (not always but sometimes).

Thank You,

Thomas
