I forgot to write I have all available serial drivers loaded, i.e. in
kldstat output

54    1 0xffffffff81ae9000     23a0 umodem.ko
55    7 0xffffffff81aec000     4d10 ucom.ko
56    1 0xffffffff81af1000     22a0 uchcom.ko
57    1 0xffffffff81af4000     2200 ucycom.ko
58    1 0xffffffff81af7000     21e0 umoscom.ko
59    1 0xffffffff81afa000     2aa0 uplcom.ko
60    1 0xffffffff81afd000     32e0 uslcom.ko
61    1 0xffffffff81b01000     2260 uvscom.ko

This is from a 13.1-STABLE system.

What you mean by configuration descriptor? Is it this:

# usbconfig -d ugen0.5 dump_all_config_desc
ugen0.5: <vendor 0x1d50 product 0x6141> at usbus0, cfg=255 md=HOST spd=FULL (12Mbps) pwr=ON (100mA)

# usbconfig -d ugen0.5 dump_curr_config_desc
ugen0.5: <vendor 0x1d50 product 0x6141> at usbus0, cfg=255 md=HOST spd=FULL (12Mbps) pwr=ON (100mA)

There is just this, nothing more. Could some usbdump help to identify
the issue? I have no experience with this, also no idea how an initial
device discovery could be catch with usbdump :(
