non-storage USB support?

    Not being able to search the forum for 'USB' is frustrating - I hope this is not a duplicate post...

    I know Tomato does not include USB support, and frankly, having some experience with the sl54 Hyperwrt builds, I would not want Tomato to even *think* about adding Samba etc..

    But there are other very interesting things one could do with the (sl54) USB port, and I wonder how hard it would be to include the level of USB driver support needed...

    For example: Many DSL and cable modems include both Ethernet and USB ports. It would be handy to be able to plug one into the router's USB port to provide a second WAN interface.

    There are two cases here:
    1) A seperate external modem (eg, you have both DSL and cable modems)
    2) Use both ports on the same modem (with differant external IP addresses)

    Case (1) would probably add lots of complexity to the software (multiple routing paths, QOS issues etc), unless it was primarily used as a failover facility.

    Case (2) is of greater interest to me, and probably something that would get broader use.

    In this case, I would be interested in two options:

    a) The USB port WAN interface to the modem could be assigned to a DMZ machine. Thus, you could create a DMZ assignment without having to disable all the other systems.

    b) The USB port interface to the modem could be used to provide a segregated WAN interface to the wireless network, thus limiting them to the same access to the wired network as the 'rest of' the internet.

    I am sure there are other interesting possibilities, including what might be done with a USB-Ethernet adapter...

    Wouldnt it be easier to add another router with a different IP and make it a DMZ? I would say the USB would probably overheat the processor worse than happens in some cases of tweaking.

    Also, I have installed plenty of modems. Most with USB support never work properly.

    Getting a wrt54g to work as a firebox is not probable.

    I agree with LeonPhelps (I hope no relation to the notorious Phelps family): Just use another box.

    I bought a router (a WRK54G) plus a decent 802.11G card for US$5 after rebate last week. Similar routers are now available for free after rebate (-tax & shipping).

    With those economics in mind it’s pretty pointless to try and hack something similar using the USB port. I understand it may pain some folks to have a feature unused, but honestly do you think the investment in time & effort could possibly pay off more then just getting a cheapie, a free, router?
