Digital cameras usually identify themselves as mass storage devices on the USB bus and this will work fine with the Subway. Another indication is whether the camera needs special drivers for Windows. If it does not, it probably will work with the Subway.
Ethernet adapters won't work. You should rather use a PCMCIA NIC which works well if you take one which is supported by the drivers.
