Will this device work from serial bus power alone.

It will function without external power. Using external means there is less drain on your (Laptop) power.

Yes. Mine has been working for 4 months with no problems, but the power is necessary.

I don't think so I tried running a couple of devices directly off the cable and it actually would fail, it works great connected to a powered usb hub

No. The unit is powered from a permanently sealed battery with 10 year life and cannot use external power, so there would be no point in doing so.

No-- the device essentially turns a single usb port into a multi function peripheral that is feeds the appropriate signal back into the primary cpu. It has its own power supply and remains on even when computer is powered down.

To power the unit, you must plug two "pigtail" USB plugs into a computer. I don't think it could really be used on much else since the software has to be compatible.

USB means Universal Serial Bus, so if you have a USB jack then it will work.

I really don't know. I use it for standard serial communication and it just works.

No, the Pi is powerful enough to power this. I've used this successfully in two Pis so far.

It will work, but you have to use your own USB power cord to connect to this device.

It should only need bus power. I have used this drive as last in chain to a powered desktop drive (FW800) then into a MacBook Pro without using an external power supply on the G-Tech drive.

Yes. You are going to need an online fuse to operate the device. I personally would not try to use it without.

Possible, but if your computer is working well otherwise to be honest your power is probably fine. It's cheap enough to try.

I haven't done it myself, but it should work fine. I have one of these. Once installed, the device appears to Windows 7 as a serial port device. If you install two of them, they will appear as two separate serial ports.You just need to make sure to wire them up appropriately.

Yes that should work, though you would be limited to the power levels delivered by a single USB port.

I have used this on a mac mini, asus mini computer, hp netbook, and my tower workstation without installing any drivers to read from it. To write to it you will need to install a burning sotware and that's it. It doesn't even require power, but it comes with it.

I can't be sure, but I would assume it would work unpowered. Every hub I've had did.
