printer cannot be detected by Octoprint even it is recognized under lsusb (Bus 002 Device 005: ID 1a86:7523) and dmesg as USB Serial

I have an old LG Optimus G phone. The only way to get it to do OTG is to connect via a powered USB hub, which I confirmed to work with other USB devices including: mouse, keyboard and USB storage. All of them got detected without issue.

However, after octo4a is successfully installed and started, I plugged in the printer but it couldnt be detected by Octoprint, when I did lsusb under web terminal , I saw the HUB and the printer are on Bus 002:

bash-5.1# lsusb Bus 001 Device 002: ID 05c6:904c Bus 002 Device 002: ID 05e3:0608 Bus 001 Device 001: ID 1d6b:0002 Bus 002 Device 001: ID 1d6b:0002 Bus 002 Device 003: ID 05e3:0608 Bus 002 Device 005: ID 1a86:7523. <--- Ender-3 printer bash-5.1#

Is there a way to troubleshoot this? Does it has to do with the way I hook up the device (via a USB hub)?

dmesg shows:

[ 2097.854112] usb 2-1.1.3: new full-speed USB device number 4 using msm_hsusb_host [ 2097.968075] usb 2-1.1.3: New USB device found, idVendor=1a86, idProduct=7523 [ 2097.968380] usb 2-1.1.3: New USB device strings: Mfr=0, Product=2, SerialNumber=0 [ 2097.968502] usb 2-1.1.3: Product: USB Serial

how can I make this work?

hi there... any possible update on this? do you have a pointer if i want to try to take a look at this?

Again, OTG is working through a hub but octa4a wont detect the printer
