Just tried a USB 2 port with a similar outcome:

kernel: usb 1-9: can't read configurations, error -32
kernel: usb usb1-port9: attempt power cycle
kernel: usb 1-9: new high-speed USB device number 23 using xhci_hcd
kernel: usb 1-9: unable to read config index 0 descriptor/all
kernel: usb 1-9: can't read configurations, error -32
kernel: usb 1-9: new high-speed USB device number 24 using xhci_hcd
kernel: usb 1-9: unable to read config index 0 descriptor/all
kernel: usb 1-9: can't read configurations, error -32
kernel: usb usb1-port9: unable to enumerate USB device

I also have Logitech Bluetooth mouse, an external harddisk, a Belkin USB-serial
adapter for my UPS, and a Canon scanner attached to other USB ports, all working
fine.

Those error messages mean that the device isn't responding to the
Get-Descriptor request.

I think a step back and checking the usb subsystem, in general, might be a good
idea:

Let's start with the full output of

lspci

and follow up with the full output of

lsusb

and lsmod

All commands should be run as root
