Thank you for bearing with me. To reiterate: I was trying palm/uppc-kmod on amd64 6.2 with standard USB stack. attach routine had the following line: err = usbd_set_config_index(dev, UPPC_CONFIG_INDEX, 1); where UPPC_CONFIG_INDEX is defined to 1. It failed with: kernel: ucom0: failed to set configuration, err=STALLED kernel: device_attach: ucom0 attach returned 6 My only change was from _index to _no and then it started to work.
