Sorry, I wasn't aware of that. usbd(4) does describe setting
environment variables in plan9.ini to change the arguments for usb
drivers (I wasn't aware of that either), but doesn't mention that you
can also do it dynamically via usbdctl. For example
echo diskargs -d >/dev/usbdctl
before plugging in the device (or -dd, -ddd etc for more verbosity).
You may need to study the source of usb/disk to make sense of the
output.
