can you turn on some of the USB_DEBUG and other options

"vmstat -u usbhist" and then put the output from it
somewhere -- it will likely be large.
at least these i think, too:
UHCI_DEBUG
OHCI_DEBUG
EHCI_DEBUG
XHCI_DEBUG
UHUB_DEBUG
UMASS_DEBUG
UGEN_DEBUG
the default history is 50k entries, so it should be more
than enough, but if not, USBHIST_SIZE can increase or
decrease it.
What Matt said...
You might like to start with just usbdebug = 1 to see why
usbd_set_config_index failed
https://nxr.netbsd.org/xref/src/sys/dev/usb/usb_subr.c#684
I did put some instructions about USB debug on www.netbsd.org, but I
can't find them now. :(
