Re: T99W175 - enable AT/COM port

I just figured out that with "AT^CUSTOMER=1" it turns into a DW5930e and I'm now able to get a COM port on Windows. This still does require the very long Linux workaround to be able to execute AT commands in the first place though.

Re: T99W175 - enable AT/COM port

It works in my 5511 just fine, they don't seem to be model locked. I guess my issues must be down to the HP version having a different VID and PID. I recompiled the Linux kernel in drivers/bus/mhi/host/pci_generic.c and drivers/usb/serial/option.c(no idea if this one was needed) to include the HP ...

Re: T99W175 - enable AT/COM port

I'm on MM 1.18.8 with kernel 5.17, it only pops up as a wireless device in lspci and its not recognized elsewhere. On windows it acts as a USB hub and exposes the network adapter and GNSS interfaces as USB ports. I did try to force the VID and PID to be a USB hub on linux but I have no idea what I'm ...

T99W175 - enable AT/COM port

I've got a HP T99W175 X55 5G modem. How would I go about enabling the COM port so I can run AT commands? The modem only has driver support on Windows and it isn't recognized by ModemManager on Linux and exposes no tty ports there either.
