Do I need to purchased an additional self powered usb hub since it the power output of the antenna exceeds the 500 mw limitation of usb devices?

Not necessary. All you have to do is be able to load the disk to your computer(that has WiFi) and plug in ANTENNA to any usb port. Wala! its working. That easy...

No, the supplied hardware is all you need. This is a great antenna for rang but they do make faster usb adapters now.

no i just pluged mine to usb on my pc and it works fine the best on the market but remember works best near a window you can point it to the direction the wifi is

I have used my Crane Super USB antenna for a bit over a year; absolutely NO complaints using the single antenna, with dual USB connections on a laptop. As I said, I do connect using the 15-foot extension cable; makes antenna placement much easier. I agree with the comment below regards two antennas, but will readily admit that I'm NOT a techie; just a satisfied user. I put this product in the increasingly rare category of "works-as-advertised". Good luck with it, and post your results!

Depending on the drive.. Some smaller (2.5", 1.8", etc) drives enclosures require no additional power and if they are capable of using a single (or sometimes dual) USB ports for operation, you will have no trouble using them with this hub. However, larger drives (3.5") enclosures must be plugged in to external power source (they usually come with power adapters). For those you will not be able to operate them with this hub only, without external power source.

It has a standard USB connection, it should power it. I don't know if the 350 has live traffic , that is what the built in antenna is for.

I know this isn't answering you question, but I don't know. I don't even use mine anymore because it wasn't so great. I recommend getting a Belkin USB hub.

USB ports can only supply limited DC power. Sometimes a two or three port passive (no power supply) USB hub can be useful, but don't expect a seven port hub to operate without a separate power supply. If you're inventive, you can construct a battery power supply with parts from Radio Shack so that you can occasionally operate away from utility power.

That other answer is not entirely correct. A powered hub can operate on USB power only. It does not NEED to be plugged into AC. It will work the same as an un-powered hub, which will limit you to a total of 500mA of current draw from all ports combined. However, if you use the AC adapter then you will have up to 500mA per-port (2A total). So if you are only going to connect low powered devices, or self powered devices, then the AC adapter can be considered optional. If you need to connect devices that draw more power (portable hard drives, USB powered scanners, burners, etc.) then you would need to use the AC adapter to supply the additional power.

I found it to work fine with only one port. I ended up getting a longer USB cable so I could raise the antenna up higher to get a strong signal...

Make sure you have the USB driver fully up to date and if you are using a USB hub that is have enough power for it.

Yes, there is a USB port on the device which will supply ample power to usb devices. I am using the 12 volt output to power a small Amateur Radio. (Approximately 2amps through the 12v output) The 5v USB out should handle everything, even tablets.

If your TV has a USB port, the antenna is powered by it. No other power source is needed.

Even if you use modified cables to get it connected, the device doesn't have enough power broadcast. I believe that the best option is to use a reapeater that has an SMA connector. I'm not sure about your application, but your solutions may deffer based on budget. Let me know if you have questions? adam.rce [at] gmail.com

It includes a micro-usb cord that powers the device from your computer and transmits data from the built in USB hub. You can buy the extra power adapter, but it is not necessary.

yes I have not had any problems with this hub powering all manor of USB devices.

I just tried mine without the power plugged in, and it worked OK with the track ball that is plugged into it. However, I suspect that any device that requires power from the USB bus (like an self-powered hard drive) would NOT work unless the hub itself is powered.

Experimentation tells me that the answer is NO. My experience with bus powered USB hubs has been problematic. Commonly you get a "power fault" on one or more of the devices involved and restoration is very difficult without rebooting (ugh).

There is nothing else attached to the unit...it's a completely stand alone device. The only exception is if you have something plugged into one or both of the USB ports (i.e. external hard drive, printer, etc.) or if you have a computer "hard wired" to one of the 5 gigaports on the back of it. None of the previously mentioned devices are required to extend the signal.
