USBIP on native_sim not working with device_next

[henrikbrixandersen]

Describe the bug

USBIP support (CONFIG_USBIP=y) seems to work only with the existing USB device stack, not with the device_next stack. I have tested this on Zephyr commit 3b03595.

Regression

• This is a regression.

Steps to reproduce

Steps to reproduce the behaviour:

• west build -b native_sim/native/64 --snippet usbip-native-sim samples/subsys/usb/hid-mouse/ -- -DCONF_FILE=usbd_next_prj.conf -DEXTRA_DTC_OVERLAY_FILE=usbd_next.overlay
• west build -t run
• usbip list -r 192.0.2.1 hangs

With the existing USB device stack, the USBIP server starts listening on port 3240 and allows binding and enumeration:

• west build -b native_sim/native/64 --snippet usbip-native-sim samples/subsys/usb/hid-mouse/
• west build -t run
• usbip list -r localhost
• sudo usbip attach -r localhost -b 1-1

Impact

Functional Limitation – Some features not working as expected, but system usable.

and setup network on the client side e.g. ./net-setup.sh start

Thanks, that did the trick. The thing, that threw me off, was that using the usbip-native-sim snippet with the existing USB device stack showed up on localhost USBIP by default, but I now realise that's due to the design of the native USB DC driver implementation - the snippet is not even useful with the existing device stack.

Perhaps we could add some sort of Kconfig setting to the usbip-native-sim snippet causing it to be incompatible with the existing device stack to avoid similar confusion? Simply setting CONFIG_USB_DEVICE_STACK=n in the snippet or adding a dependency on this not being set for enabling CONFIG_USBIP would do the trick.
