Hello there! Sure, here is what I get if I use lsusb -vd 1519:0020

lg-p895:~$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux 6.16.0+ ehci_hcd EHCI Host Controller
Bus 001 Device 002: ID 1519:0020 Comneon HSIC Device
lg-p895:~$ lsusb -vd 1519:0020
Bus 001 Device 001: ID 1d6b:0002 Linux 6.16.0+ ehci_hcd EHCI Host Controller
Bus 001 Device 002: ID 1519:0020 Comneon HSIC Device
lg-p895:~$ lsusb -vd 1519:0020
Bus 001 Device 001: ID 1d6b:0002 Linux 6.16.0+ ehci_hcd EHCI Host Controller
Bus 001 Device 002: ID 1519:0020 Comneon HSIC Device

regular lsusb is added for reference.
