I need to maintain 2 network connections on a Windows Mobile 6.x. When I plug in with the second USB to Ethernet device, it disables the previous one after about 30 seconds. How do I keep both of them enabled?

I'm planning on building a cluster of 5 or more rpi4b (v1.1).
Tutorial for that: Build a Raspberry Pi Cluster Computer
All is fine and dandy except for the power supply for all the units.
I have no intention of having individual cords from each unit to the wall, so I thought of a USB hub power supply with multiple ports. This would also allow me to increase the unit count in the future will less hassle.
Also, assume an ethernet cable and a small SSD drive connected via USB per unit. No screen or HID device connected.
What would be a good fit for running the cluster 24/7?
I thought of these:
IWAIVON USB Wall Charger
Anker PowerPort Speed 4 Port
Anker PowerPort 10
RavPower Prime 60W 6 Port
Assuming that every USB port in the hub will be (eventually) connected and having in mind that RaspberryPi4B v1.1 specs states that it requires a 5v/3A power supply which none of these supply, what will be a good USB hub power supply? It doesn't have to be one I listed...
I have a RaspberryPi which is configured to automatically connect to my iPhone's wifi hotspot. I need to take the RaspberryPi to various locations for testing, and I often need to leave it at a location for extended periods of time (without my iPhone hotspot there). The RaspberryPi needs an internet connection in order to complete the testing properly.
I am trying find a solution which would allow me to SSH (or connect some other way) into the RaspberryPi while it is connected to my iPhone's wifi hotspot. This would allow me to add a new wifi network/password when I move to a new location (I usually can't get the wifi network/password in advance). In other words, I would move into a new location, the RaspberryPi would be connected to my hotspot and would begin testing, and once I obtain the wireless network/password for that location, I want to connect to the RaspberryPi to add that information so it can connect to the location's wifi network instead of my hotspot.
I don't have a portable monitor for the RaspberryPi so I can't just hook it up to a screen and make the changes that way.
Does anyone have any suggestions? Thanks in advance.
On the phone running this hotspot, I am assuming you can install apps that permit you to SSH into the Pi, headless? I'm doing this regularly, my choice app is JuiceSSH.
Alternately, a laptop connected to the same phone hotspot running an SSH client such as Putty can connect to the Pi across the same AP, also headlessly. You can update your WPA_supplicant file and reboot the Pi, making sure to bring down your hotspot before it fires up again and joins the new AP. I'm also doing this regularly.
Given the time (4 months) that's passed, you've likely figured this out already...
Got a Raspberry Pi 2 running Raspbian which shares its PPPoE Ethernet connection via Wi-Fi (basically, serves as a geeky home access point).
Is it possible to obtain this setup using Windows 10 IoT?
I heard you can do it with the right Wifi adapter (Windows 10 Iot drivers are limited):

I bought an Bluetooth ELM327 to read codes out of my cars diagnostic ports
I connect to it via Bluetooth in windows and it makes a serial-over-bluetooth com port 4
which any application running on my windows will connect quite happily.
I then found a few apps for the iphone and android etc that connect to these ELM gadgets via WIFI and not Bluetooth (because for some reason you cannot pair to these devices of iphone)
Now obviously I can buy a WIFI enabled ELM327 - but it costs £130 and my Bluetooth one cost £15
So after reading about this a bit I found out that the WIFI enabled ones you connect up as ad-hoc network and the smartphone(iphone) app tenets in port 23 that relays normal serial commands.
So obviously in the WIFI enabled one there must be some processor that runs an nano-os with telnet and some rs-323 translators and not sure what else.
How, using Windows 7 will i be able to relay any incoming WIFI requests for Telnet port 23 to my COM 4 that is connected to my Bluetooth ELM327 ..
As this is surely all that is needed by the Smartphone app.
You dont have to connect using a Bluetooth library like suggested ... because you are already connected to the device and have COM4 exposed to you. SO all you have todo is use a telnet library and translate and handle the handshake then realy the infomation as serial data.
There's no feature built in to Windows (or any other platform I know of) for such a scenario.
It would be fairly straightforward however to write a program to listen on port 23 and open a bluetooth connection when connected to, and then forward the data received on each connection out onto the other.
For instance one could use my .NET library 32feet.NET (e.g. http://32feet.codeplex.com/wikipage?title=General%20Bluetooth%20Data%20Connections etc etc) along with TcpListener from the .NET framework class libraries.
I want to monitor the HTTP traffic sent/received from my iPhone. The iphone is connected to the Internet via my wifi router.
I want to capture packets from my windows 7 station.
Thanks for your help.
You have a few options here:
If your wireless router has a port mirroring or port spanning feature, turn it on and point it at your workstation's IP. Use Wireshark on your workstation to look at the packets arriving on the interface assigned to that IP.
If your workstation has a wireless card, get Connectify for Windows 7 (turns wireless card into Wifi Hotspot). Connect iPhone through Windows 7 wireless, and workstation through ethernet to the internet. Your workstation will effectively act as a router for your iPhone and you will be able to record iPhone's packets passing through it.
Get an ethernet hub (make sure it is not a switch, you won't see all packets on every interface with a switch), and connect your workstation, wifi router and internet to it.
Get a switch with port mirroring feature, configure port mirroring to forward a copy of all packets to your workstation.
Another option that I wish someone would have mentioned to me is pfSense. This is an operating system based on BSD made to serve as a firewall. Top of the line routers have, say 400 Mhz of processing speed, and unimpressive amounts of ram. The lowest-end computer you'll find these days has better specs than that, and of course, it's upgradeable. You don't have to bother with those terrible Cisco licenses (no DHCP with no license, 20 DHCP users at one license level, 100 users at an higher lever? Ludicrous), etc. Best of all, you have "root' access to the system, so you can run whatever you want on it (including wireshark, say)!!
Make sure you have two sufficiently fast ethernet cards. You'll set your wireless router to not do NAT (because pfSense will be doing that), then you can get to work setting up your VPN server, etc. without thinking about cisco licensing, etc.
