  • how to effectively use usb ports?

    I have a mobo with 4 usb ports (no pci/agp/mini-pci/pci-express):

    The question is how to connect the following list of devices in the most cpu effective way:
    1. touch screen (usb)
    2. obd reader (usb)
    3. radio (usb)
    4. webcam 1 (usb)
    5. webcam 2 (usb)
    6. wifi (usb)
    7. gps (usb)
    8. bluetooth (usb)

    I guess I need the usb hub and plan to connect them in the following way:
    1. USB1: touch screen
    2. USB2: radio
    3. USB3: gps
    4. USB4: HUB: obd reader, webcams, wifi, bluetooth

    Does it make any sense re cpu load and the whole system balance?

    There's no issue with CPU load as far as what device is connected to what USB port.
    USB is USB is USB.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

      There exist combo wifi/bluetooth adapters - can save you one port.

      FWIW,

        With so many devices, you should use a powered USB hub. I had problems with a regular unpowered hub on my home PC with less than that amount.

          My advice; if you're half way technically savvy then it might be an idea to (a) use powered hubs and (b) modify said hubs so they'll ONLY be powered by the external power and not through the PC. This keeps the load down on the PC and keeps your potentially long USB cables from screwing stuff up.

          I'm doing similar. My mobo has 2 USB ports and I have two 4-port powered hubs I'm installing. One of these is going to run from the trunk (install location of the PC) all the way to the dash of the car, the other's going to be mounted next to my PC. Both hubs will have external power, neither of them will use USB power from the PC.

            Important is only to separate it according to bandwidth they need.

            Radio should be on a separate port (also a usb soundcard, usb hdd, and probably webcams), the rest makes no difference.
            Also I would think of what i want to use together...

                  Looks very interesting!
                  Price is not bad either.

                  Don't know if it supports Widcomm though.

                    I found wifi didn't like hubs much - but gps is low bandwidth and is fine on a hub.

                      Just bought one for my home PC. It comes with BlueSoleil software, so, given Broadcom licensing policy, I doubt you will be able to use it with Widcom/Broadcom stack without some hacking.
