Description
I am having an issue using the TTGO T-Display device with the Jade on Android. When connecting via cable using the latest Blockstream Green software, the connection is not established. The Jade remains on an infinite "check-in" screen until a network error or timeout occurs.

Version
Jade firmware: 1.0.32
Software: Blockstream Green (latest version at the time of testing)

Steps to reproduce
Connect the TTGO T-Display device and the Jade via cable to an Android device.
Open the Blockstream Green software.
Attempt to establish a connection with the Jade.
Expected behaviour
The connection should be successful, allowing access to the device.

Actual behaviour
The Jade gets stuck on an infinite "check-in" screen, resulting in a network error or timeout.

Screenshots
N/A (issue not directly related to the GUI).

Device or machine
Device: TTGO T-Display
Operating system: Android
Jade firmware version: 1.0.32

Additional info
The Bluetooth connection works perfectly in the same environment and with the same device, indicating that the problem is related to the cable connection.

I've had this problem occurring to me since mid-March/April (maybe earlier). This problem occurs not only with me, but also with friends of mine. These friends who did not buy the device in the same place as me, that is, the problem is not with the device, but I believe it is some part of the firmware that does not recognize the cable for data transfer, even if it is a high-quality cable or a cell phone.

I use the same hardware on my Jade DIY wallets, TTGO T-Display.

I connect it to my Android Phone with a USB-C to USB-C male to male cable. And this power up the device.
But when I try to use the Jade DIY. It asks me for the PIN. And then stays in "Check in" and that's it.
When I use BT on that Jade it works fine. No problem at all.
I tested this with more that one TTGO T-Display and USB cables.

Maybe it's related with the device being powered by the phone itself.
