Hi,
I'm working on porting my software projects from NCS2.9 to NCS3.1.1 and run into the problem that the thumbs
nrf52840-dongle and arduino-nano-33-ble are not booting anymore.
Curious, the nrd52840dk works great after fix up all obsolete functions (specially for the openthread coap)

I had looked around to see if the dfu-loader for the PCA10059 (v2.1.1 2022) needs to be updated?
Same for the bossac loader of the Arduino with the nrf52840.
The PCA10059 shows in the Linux kernel log a new hi speed device and timed out with a read64 error and restart after a while.
The Arduino keeps rebooting and the kernel log shows the usb-device disconnect/reconnect.
Anything you can tell me?
