I have a strange issue I started to see on RELENG11 and RELENG12 that I am not sure when it started or if its always been there. On an PCEngines APU3, with an LTE modem that works with the u3g driver, it will fail to attach if the box does not boot up fast enough. So I am guessing something gets messed up in initialization and timing ?
e.g. in loader.conf I have autoboot_delay=2 dcons_load="YES" amdsbwd_load="YES" u3g_load="YES" beastie_disable="YES" comconsole_speed="115200" console="comconsole" #hw.usb.debug=1 If I pause at the boot or make the delay say 10 seconds, the device often errors out. The device normally looks like this ugen2.1: <AMD EHCI root HUB> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA) ugen1.1: <AMD EHCI root HUB> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (0mA) ugen0.1: <0x1022 XHCI root HUB> at usbus0, cfg=0 md=HOST spd=SUPER (5.0Gbps) pwr=SAVE (0mA) ugen2.2: <vendor 0x0438 product 0x7900> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (100mA) ugen1.2: <vendor 0x0438 product 0x7900> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE (100mA) ugen2.3: <HUAWEI Technology HUAWEI Mobile> at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (500mA) ugen2.3: <HUAWEI Technology HUAWEI Mobile> at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (500mA) bLength = 0x0012 bDescriptorType = 0x0001 bcdUSB = 0x0200 bDeviceClass = 0x0000 <Probed by interface class> bDeviceSubClass = 0x0000 bDeviceProtocol = 0x0000 bMaxPacketSize0 = 0x0040 idVendor = 0x12d1 idProduct = 0x1573 bcdDevice = 0x0228 iManufacturer = 0x0002 <HUAWEI Technology> iProduct = 0x0003 <HUAWEI Mobile> iSerialNumber = 0x0004 <0123456712ABCA17> bNumConfigurations = 0x0003 But about 50% of the time with a longer delay, at bootup time I get uhub4: 4 ports with 4 removable, self powered usb_alloc_device: set address 3 failed (USB_ERR_STALLED, ignored) usbd_setup_device_desc: getting device descriptor at addr 3 failed, USB_ERR_STALLED usbd_req_re_enumerate: addr=3, set address failed!

Enabling debug will make it fail. Any idea what it might be or how I can tweak it to it more reliably initializes ? I first start to notice it when I added a few more klds at boot time. This made the boot up process that much longer that I would run into this issue periodically. ---Mike -- ------------------- Mike Tancsa, tel +1 519 651 3400 x203 Sentex Communications, m...@sentex.net Providing Internet services since 1994 www.sentex.net Cambridge, Ontario Canada _______________________________________________ freebsd-usb@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
