FTDI not working in rear USB Port

Hello,
I’ve installed kmod-usb-serial-ftdi package and then connected a Hardwario Radio Dongle to the rear USB port of my Omnia and it wasn’t recognized as a TTY port. And also nothing was listed in lsusb output.

In dmesg I see this output:

[ 1232.252294] usb 4-1: new full-speed USB device number 3 using xhci-hcd
[ 1232.433222] usb 4-1: unable to read config index 0 descriptor/start: -71

[ 1233.850150] usb 4-1: can't read configurations, error -71
[ 1233.855897] usb usb4-port1: unable to enumerate USB device

When I’ve connected a dongle to a front USB port, everything works fine and ttyUSB0 is available.
I thought that maybe that rear USB port is dead, but I tried to connect USB2 and USB3 flash drives and both of them have been recognized successfully even when connected to the rear port.

Omnia is running the latest TurrisOS 5.1.9 version.

EDIT:
I tried to rollback to a factory version (Turris OS 3.2.1) and the error when connecting the dongle to a rear port is the same one (error -71) as on TOS 5.

Is there anything to check, please?

It might be related to usb hubs. Some devices dont work after being connected to two usb hubs in a row. Just a lucky guess. Chceck dmesg -w when you connect to working usb port.
