Hi.
I have seen this issue since december 2008. I have 3G EvDO modem
Novatel U-727. It fully supported by u3g driver except this issue with
replugging.
If I kldload u3g driver and replug modem i have the same messages:
> $ kldload u3g
> <plug in UMTS device>
> dmesg:
> usb_test_autoinstall:571: Eject CD command status:
> USB_ERR_NORMAL_COMPLETION usb_alloc_device:1781: Found Huawei auto-install
> disk!
> ugen0.2: <Novatel Wireless> at usbus0
> ugen0.2: <Novatel Wireless> at usbus0 (disconnected)
> uhub_reattach_port:440: could not allocate new device!
>
HPS:
Your patch resolved for me this problem. Thanks.
I tested replugging modem, device attach correctly,
