MiFi 8000 USB connectivity issues
« on: June 12, 2020, 08:07:32 pm »
I'm trying to attach a MiFi 8000 LTE hotspot (from calyxinstitute.org) to my fitlet2 (https://fit-iot.com/web/products/fitlet2/) running opnsense and use it as a fallback source of internet.
I am running OPNsense 20.1.7-amd64.

Whenever I connect it, for about 5 seconds I get the "ue0" interface, but then it immediately disappears.
The device itself will ask me if I want charging or charging+tethering. Tethering is the default when I plug it in and it doesn't seem to change.

This is the matching dmesg output:

ugen0.2: <Novatel Wireless MiFi 8000> at usbus0
cdce0 on uhub0
cdce0: <CDC Ethernet Control Model ECM> on usbus0
ue0: <USB Ethernet> on cdce0
ue0: Ethernet address: 00:15:ff:xx:xx:xx
uhid0 on uhub0
uhid0: <HID Interface> on usbus0
ugen0.2: <Novatel Wireless MiFi 8000> at usbus0 (disconnected)
cdce0: at uhub0, port 10, addr 27 (disconnected)
cdce0: detached
uhid0: at uhub0, port 10, addr 27 (disconnected)
uhid0: detached

usbconfig output:

Quote
# usbconfig
ugen0.1: <0x8086 XHCI root HUB> at usbus0, cfg=0 md=HOST spd=SUPER (5.0Gbps) pwr=SAVE (0mA)
ugen0.2: <Novatel Wireless MiFi 8000> at usbus0, cfg=0 md=HOST spd=SUPER (5.0Gbps) pwr=ON (224mA)

It seems that the code to support it was pulled in with 20.1.7: https://github.com/opnsense/changelog/blob/master/doc/20.1/20.1.7

Specifically this commit: https://github.com/opnsense/src/commit/f3b129a428da2600853c67667ce6229572207076

Anyone got an idea about why it might just disappear?

Hmmm... I wonder if that's the issue:

This is mine:

Code: [Select]
root@OPNsense:~ # usbconfig -d 0.2 dump_device_desc
ugen0.2: <Novatel Wireless MiFi 8000> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)

  bLength = 0x0012
  bDescriptorType = 0x0001
  bcdUSB = 0x0200
  bDeviceClass = 0x0000  <Probed by interface class>
  bDeviceSubClass = 0x0000
  bDeviceProtocol = 0x0000
  bMaxPacketSize0 = 0x0040
  idVendor = 0x1410
  idProduct = 0xb020
  bcdDevice = 0x0318
  iManufacturer = 0x0001  <Novatel Wireless>
  iProduct = 0x0002  <MiFi 8000>
  iSerialNumber = 0x0003  <0123456789ABCDEF>
  bNumConfigurations = 0x0003

This is the one from https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=245152
Code: [Select]
# usbconfig -d 1.2 dump_device_desc
ugen1.2: <Novatel Wireless MiFi 8000> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (224mA)

  bLength = 0x0012
  bDescriptorType = 0x0001
  bcdUSB = 0x0310
  bDeviceClass = 0x0000  <Probed by interface class>
  bDeviceSubClass = 0x0000
  bDeviceProtocol = 0x0000
  bMaxPacketSize0 = 0x0009
  idVendor = 0x1410
  idProduct = 0xb022
  bcdDevice = 0x0318
  iManufacturer = 0x0001  <Novatel Wireless>
  iProduct = 0x0002  <MiFi 8000>
  iSerialNumber = 0x0003  <0123456789ABCDEF>
  bNumConfigurations = 0x0001
Maybe the mismatch in idProduct is an issue?

Re: MiFi 8000 USB connectivity issues

The product ID (or idProduct) isn't used.  It is determined by the flags that are presented from the USB device.
Code: [Select]
/* Novatel Wireless 8800/8000/etc */
{USB_IFACE_CLASS(UICLASS_IAD), USB_IFACE_SUBCLASS(0xef),
USB_IFACE_PROTOCOL(UIPROTO_RNDIS)},
When the USB interface from the device presents itself and all of its options to the OS, it uses flags to communicate what functions it can perform.

That flag is there below in your full dump. 

Here are the same dumps from mine:

"Sharing" the internet via USB does have to be enabled in the modem.  If not, the interface will just disappear and not return until it is re-enabled (in the modem). 

Once it is re-enabled in the modem, in my experience, OpnSense won't just bring it up.  I have to manually bring the interface back either via a reboot or through the web GUI.  It is there, but won't be assigned its static IP or begin passing traffic.

Check out the post here: https://forum.opnsense.org/index.php?topic=16166.msg82675#msg82675

There is also a binary if_urndis.ko module that seems to work fine with the kernel in the 20.1.7 release.

Thanks.

Oh nice, thanks for the heads up!

Also: concerning that the patch was committed but the module was the old one O_o
