Is the device compatible with a powered USB hub?

Yes. I use mine to download DSC fire & security panels. Just make sure that you donload and install the Tripp-Lite drivers that are on the CD that came with it. If you can't find them, let me know and I'll send you a set.Jim RaposaCOMMSOUND Company jim@commsound.net

As far as I know, it is. I have used it at several sites with a powered hub that I keep in my "bag of tricks" since my Netbook only has 2 USB ports and it worked fine.Jim RaposaCOMMSOUND COjim@commsound.netps.. Make sure you install the Tripp LLite drivers that comes with the Keyspan on whatever computer you are using it with.

Yes, I bought one and use it to power a USB hub that my printers are connected to. Works great, no problems

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.

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.

yes, but but external drives suck up too much power for most hubs, like this one. Mouse, keyboard work fine, so try to connect external drives directly to computer.

It's a powered hub, but I don't know that it's THAT powered. I would NOT take the chance

You have to have a usable USB port in order to utilize this hub. It could work with a "weak" USB port, but it may not support too many devices.

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

Yes. The manual clearly states that external power is required at all times. USB 3.0 ports are supposed to provide up to 900 mA, each, so requiring an external power source for hubs is pretty much written in stone. Also, it is worth noting that older computer systems probably do not have USB 3.0 ports built into them. My own laptop is a 2011 ThinkPad, and I had to buy an adapter card to get the support.

Only if you want to provide power to a USB device that you plug into the hub.

Yes it is. Assuming you don't run it from a USB hub as possibly won't have enough power then.

It depends on its power usage. It may require the full 500mA coming from your computer's USB port. A hub shares its power limit across its ports. As long as no other devices attached to the hub require port power, it should work fine attached to it. If there is any doubt, don't do it as you are running the risk of data loss and physical damage to the card(s) and/or reader.

No. It has neither the connectivity nor the power. Any single USB device up to 2.1 amps, and 3.1 amps max output for multiple devices.

I'm not the seller, sorry. I'd suggest looking up some installation guides because it can be a little tricky I had to buy a powered USB hub when I got mine.

In general, I have found that the USB hubs that supply a wall-wart for power to the hub, do indeed NEED the power to the hub.Dick

It worked when connected directly to my laptop, but not when connected to a USB hub. It may require more power than available from a non-powered hub port. Good luck.

i do not recommend buying a USB powered Hub for external drives. Buy the one with external power. The USB powered one will turn off your HD sometimes and it is annoying esp if you are downloading files.
