That does not look like a printer, but like a standard usb mass storage device,
maybe your printer has a build in hub and shows up as multiple devices?

Once your printer shows up in lsusb in the client, then the client should
redirect it without issues. If you think filtering is the problem try
going to File -> USB device selection, the filter only influences auto-redirection,
you can always manually redirect. Also note that auto redirect only works
if the remote-viewer window has focus while the device gets plugged in.
