Hi guys. I have a device[1] that is recognized on Linux by the generic CDC-ACM driver and I'm trying to do the same on FreeBSD current with umodem (4). But, as you can see, I had no success:
Jun 1 20:00:54 BARAD-DUR kernel: uhub_reattach_port: port 1 reset failed, error=USB_ERR_TIMEOUT Jun 1 20:00:54 BARAD-DUR kernel: uhub_reattach_port: device problem (USB_ERR_TIMEOUT), disabling port 1 Jun 1 20:00:55 BARAD-DUR kernel: ugen0.3: <www.recursion.jp> at usbus0 Jun 1 20:00:55 BARAD-DUR kernel: umodem0: <www.recursion.jp USB-232, class 2/0, rev 1.10/1.00, addr 3> on usbus0 Jun 1 20:00:55 BARAD-DUR kernel: umodem0: data interface 1, has CM over data, has no break Jun 1 20:00:55 BARAD-DUR kernel: device_attach: umodem0 attach returned 6 Jun 1 20:00:55 BARAD-DUR kernel: umodem0: <www.recursion.jp USB-232, class 2/0, rev 1.10/1.00, addr 3> on usbus0 Jun 1 20:00:55 BARAD-DUR kernel: umodem0: data interface 1, has CM over data, has no break Jun 1 20:00:55 BARAD-DUR kernel: device_attach: umodem0 attach returned 6 Have you some tip for me to make this work on FreeBSD? I had put some 'printf' at the source code and noticed that umodem_attach() failed at line 378 [2]. The main reason is basically that the usbd_transfer_setup() got an endpoint [3] with 'ep->methods == NULL' [4] and this leads to "USB_ERR_NO_PIPE" on [5]. Thanks.
