Thanks for the pointer!  It looks like I need to try a powered
hub:

laptop# usbdevs -v
Controller /dev/usb0:
addr 1: full speed, self powered, config 1, UHCI root hub(0x0000),
 Intel(0x0000), rev 1.00
port 1 addr 2: full speed, power 300 mA, config 1, USB 2.0 Ethernet
 adapter(0x1040), BayNETGEAR(0x0846), rev 0.01
port 2 powered

I'll scrounge up a powered one and report back.

Thanks again.

Andy
