You may also find ftpd-topfield (FtpdTopfield) as a useful means of communicating with your NSLU2.
Originally developed to turn an NSLU2 into an Ethernet interface for a Topfield TF5000PVRt or TF5000PVR.
These days, puppy runs on a variety of Linux systems, including x86 desktops, amd64 servers, PowerPC
based CD players, and MIPS based wireless routers.

ToFu is a tool to allow the firmware in your PVR to be updated via a USB connection
from a Linux/UNIX system. The download link provides source code, which you will

Several new USB devices (especially high-speed WAN stuff, they're expensive
anyway) have their MS Windows drivers onboard; when plugged in for the first
time they act like a flash storage and start installing the driver from there.
After that (and on every consecutive plugging) this driver switches the mode
internally, the storage device vanishes (in most cases), and a new device (like
an USB modem) shows up. Some call that feature "ZeroCD".
