Sierra 7355 help

Check the USB IDs it reports with: usbconfig -d ugen1.2 dump_device_desc

It shows as a Dell device so it will probably require setting to a different USB composition. You will need to do that in Linux or Windows if so.

@stephenw10 it shows ugen1.2: <Sierra Wireless, Incorporated Dell Wireless 5808 Gobi 4G LTE Mobile Broadband Card> a, 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

Yes that's a Dell Vendor ID and a Product ID that isn't known:

You will need to update the USB composition and identity. Similar to this:

EDIT - GUIDE BELOW - POSTING ALSO IN MAIN FORUM POST (MC7355 INFORMATION WAS EVERYWHERE SO I WILL PUT THE STEPS BELOW TO HELP SOMONE)

1. Load Windows 10/11
   2.Go here - https://zukota.com/posts/sierra-wireless-em7455-how-to-enable-com-ports/. - Download the .IMA and make the USB as the guide describes and follow the steps.
   3.Back to windows - Follow the the BELOW guide up to the point where it says to connect to the COM port in windows via PUTTY
   https://zukota.com/posts/sierra-wireless-em7455-how-to-make-it-work-with-an-older-lenovo-laptop/
   4.Type the following in Putty once connected to the com port AT!UDVID=1199 and AT!UDPID=9041 and then at!reset
2. back to PFSENSE, it should now show at least

I assume you found the correct port for the AT interface?

@stephenw10 It now shows 4 options in Pfsense, do you have any information on finding out which one to set as the gateway/interface in PPP?

I actually had a read of your old posts here, any idea why after it shows connected with "cu -l /dev/cuaU0.2" I cannot type anything after? I have to close the SSH session?

I now have 4 options /dev/cuaU0.0, /dev/cuaU0.1, /dev/cuaU0.2 and /dev/cuaU0.3

and it now shows as ugen1.2: <Sierra Wireless, Incorporated MC7355> at usbus1, 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 = 0x1199

@nanoken said in Sierra 7355 help:

It might just not be configured to reflect back the characters you're typing. Try just entering: at at that port and see if it returns OK.

If you run usbconfig dump_all_config_desc against the device you will see the descriptions of each interface.

@stephenw10 I have no idea why but now it won’t show it as a option again in interfaces. So I have no ‘dev//cua.. option at all.

ugen1.2: <Sierra Wireless, Incorporated MC7355> at usbus1 shows Still though so it’s defo connected.

I thought this chip was the easier one to be honest, shame as I bought the aerials and wanted it all in one box. If it comes to it do you know any mpcie that just Works with eu sims?

[stephenw10]

Did you change the USB IDs? Is i still showing as those?

The USB serial devices in /dev are created by u3g when it recognises a device. So if it isn't creating them it's not seeing a device it supports.
