Would this operate properly plugged in to a non-powered hub?

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.

I quit using the iPod on my trucks receiver and plugged this reader into the USB port on the back of the receiver. I now just use Sandisk 32Gb SDHC card for my music. It makes it easier to manage my files than the iPod.

I just plugged mine in to check, and the answer is no. Mine is powered up and functional with my battery pack out.

I can't see why not as this is just a basic USB hub that should work with any USB jack, and due to the ability to plug in to home power source I have run 4 or 5 items at a time with this hub with no problems!

I don't know for certain if the computer connection is cut off. I do know the power is cut off which in most cases would cause what you have connected to not function. I often use the hub in conjunction with a couple of led lamps as makeshift desk lamp when travelling.

No. It is *not a powered hub* and for the record, this is not just a "hub" in the normal sense. This is to switch up to 4 USB devices between 2 computers. I use it for a mouse, keyboard, and microphone and for those devices it works fine. This includes a Razer mouse that does not fully work with at least some other KVM solutions.

No, it does not. It won't function as a hub without the power source either (at least not to devices that require power, eg, my WiFi card)

Genevieve, I would think it would fine as long as the devices on the USB hub don't require much power to operate, but any device that gets its power only from the USB port and has no power supply of its own could suffer, but I just don't know for sure since all I used it for was a printer and the printer has its own power of course. I wish I could give you a definitive answer on the power part, but I'm sure it would work with a USB hub just fine, especially if the hub has a power supply for itself.

It does require a direct connection since it does not require any software to run it. As far as I know, it will not work in a hub.

The recommended way is to use a powered USB hub. The Pi is a bit power hungry requiring up to 700 mA to operate. Many use a small cell phone charger to operate it and a lot of them are only 1 amp, which doesn't leave a lot of excess power to run the other components. If the Pi doesn't get adequate power there can be some intermittent operating problems. The answer that Noel provided below is using an external 4-port hub, which I assume has its own power supply. Spend a few $ and get a powered hub!

I use the USB switch with a powered hub. (The switch has no external power.) If you need a powered hub, I don't know. I changed to using a powered hub and have found the hub more reliable than a non-powered hub.

Yes you sure can however be advised that I think you should use a powered USB hub... I have a wireless mouse and keyboard, a gigabit wired network adapter, and I have hooked up external drives to it... No issues... However one issue I have noticed: if you leave this thing unplugged for too long it forgets itself and you have to perform a reset up of all your stuff.. On the flip side if you leave it plugged in all the time it is frozen and you have to reset it.. I'm thinking about putting a timed outlet controller on it so it resets daily to prevent that..

no ... it plugs into a receptacle ... you should have to use a switched receptacle

Yes, depending on its configuration ...but your devices will take a long time to charge. I would use several chargers instead of a hub....but that is me.

yes. It's a fairly high powered hub. Works best if plugged into a USB 3.0 port on a computer.

Obviously the unit needs to be powered for it to be function. The top left "input" on the unit is for 12v in. The wall power adapter that comes with the unit needs to be plugged in, coax from that right into that port is how you accomplish that. I hope that answers your question.

Should work as long as the device not being used is completely powered off.

The manufacturer says this: When the hub's power adapter is not connected, the hub is capable of running purely from bus power (from the host PC). When a hub reports itself as bus powered to the OS, the OS looks in the USB descriptors for every attached device, sees how much power the device reports that it needs reserved for it, and pops up a error (and possibly disables devices) if the total amount of power requested exceeds what a bus-powered hub in theory can count on pulling, which is 500mA for USB 2.0/1.1. We recommend always using the power adapter for best results.
