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 dynamical
you can enable debug diagnostics for devices by using the usbd ctl file.
I don´t remember which ones are the strings (see the man, probably) but
I remember you can enable debug flags without restarting it.
You could try to locate them and enable debug for that, plug the disk
again, disable

Try 'cat /dev/sdU0.0/ctl' to see if usb/disk has got the
geometry wrong.

Try invoking ext2srv with '-v' to get more diagnostics.
Try 'dd -if /dev/sdU0.0/data -of /dev/null' to see if usb driver
is having trouble reading

It appears you have no partition table
