I bought a new powered hub.
Its documentation claims that it can do 500ma per port.
blinky still doesn't blink.
I've got both boards connected to the hub,
but only one shows up:
[root@localhost gdm]# lsusb

Bus 001 Device 006: ID 1fc9:0009 NXP Semiconductors
On the LPCX board, the connector is the one beyond the base board.
On the base board, the connector is the device connector next to the host connector.
From dmesg:
