USB devices and PCIe "freeze", lsusb -t hangs

I have a PC running RaspbianOS (I have to) that has a PCIe card connected to it, the PCIe card has 4 USB controllers for 4 ports(StarTech PEXUSB3S44V).

I have a Sipolar industrial 10 port USB hub connected to 1 port and then I connect 10 Huawei 4G USB modems to the hub. I reboot all of the modems every minute using a script I wrote, using their WebUI.

When I connect the hub into 1 particular port, it works flawlessly, however, when I connect the hub to a different port, some modems disappear after a few hours (around 20) of rebooting.

This is the part in my /var/log/messages that stands out since it never appears for 20 hours and after it appears some of the modems never come back again.

Some things to note:

1. lsusb works, lsusb -t hands forever, can't even ctl-c to stop, have to close terminal window and open a new one.
2. I have tried resetting the PCI using echo 1/0 to/reset and /power, the commands hangs with the same behavior as lsusb -t.
3. Restarting the PC makes the missing modems come back.
4. Tools like hub-ctl, usb-reset and uhubctl hang with the same behavior as the rest.

At first, I thought it was the specific USB controller that this port belongs to, but the rest of the modems work fine and they are connected to the same controller, this makes me believe that this is actually a software problem.

Any ideas?
