This is generating a lot of grief and appears to be unnecessarily
strict. Common USB sticks with a MaxPower value just above 100mA, for
instance, typically work fine on unpowered hubs supplying 100mA.
Is a more user-friendly solution possible? Could the shortfall
information be passed to udev, which would allow rules to be written per
device?

Yes, it sounds like we're being non-real-worldly here. This change
apparently broke things. Did it actually fix anything as well?
I think a far more sensible approach would be to just ensure that the
total current draw for the (unpowered) hub and all connected devices,
stays below the 500mA allowed. So a 200mA device could coexist with
a 100mA device on a hub which itself steals 100mA.
Cheers
