Can this hub work without the power adapter plugged in (i.e. work off the computer usb connection)?

Yes, it works just fine plugged into a workstations USB port. I use the end port (power) to charge my phone while I'm at my desk.

Dear Annabelle, Unfortunately, our Premium 4 Port USB Hub is not powered, and will not power an external Superdrive (which is the case with most USB hubs) as they require over 500mA. The total amount of power going to the hub may not exceed 500mA. If you have any other questions or concerns please let us know. Thank you,Satechi Technical Support

Yes. I had an SSD drive connected to the back of a server's USB 3 port for weeks without issue with no external power adapter.

It does not require the use of the AC adapter, it will work without the AC adapter being plugged in. It will only work, however, as good as any non-powered USB hub, meaning, there would be a limit to the amount of power that can be used by the devices connected, some devices will require the additional power, that is the advantage of the additional AC Power source.

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 doesn't need a separate power supply, it can draw the power from USB port on a laptop. If you intent to connect it to an USB hub, make sure that the USB hub can provide sufficient power. Non/low powered USB hub will not work.

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.

No, the power adapter is for the IDE/laptop hard drives. I have recovered data from SATA drives without the adapter in place although I normally leave it connected for convenience sake.

The hub can be powered by the AC adapter and or USB. I have one and I use it to dj. It is nice because if my computer looses power my controllers stay on because the hub is plugged directly into the wall. Don't get the USB 1.0 version I have it and it is terible. I went back and bought the 3.0 and it works great. I run a USB powered light of it so the on off switches are nice. Hope this helps.

Definitely no! Without power it's totally dead - like a stone! You must connect it to power and then you can expect it to work - if there is no anything other wrong. If you don't want to use power, you can check another model - http://www.amazon.com/Anker%C2%AE-4-Port-Portable-Aluminum-2-Foot/dp/B00IJ331WY/ref=sr_1_2?ie=UTF8&qid=1416424283&sr=8-2&keywords=anker+usb+3.0+hub. It has only 4 ports and cannot charge devices, but it's more compact and doesn't power connection at all.

Yes. However it depends on the device you are plugging in. If the device is BUS powered, then you will need this HUB to be plugged in a power source as it will need to send power to the bus powered device (for example flash drives or USB powered Mics) If the device has its own source of power (like a camera or a powered external hard drive) then you do not need to plug the HUB into a power source and can serve as a pass through.

This hub isn't for doing that. It's for adding USB slots when your computer's USB slots are filled. I have USB lines from two external drives, a printer, a mouse, and a cooling pad hooked up to my hub. You'll still need to plug your external drives power adaptors into a suge surpressor.

Depends on what devise you have plugged in. A usb stick should work without the power cable, external drives would not.

It should work but u may need a powered usb hub as this adapter is power hungry

I haven't tried either, but it should work. Since the hub takes up more space in a small area that I like, I don't use with my laptop.

Hi Nicolas Raddatz, No, this hub is self-powered, so it needs the AC adapter is plugged to ensure stable performance. Anker Team 1-800-988-7973 support@ianker.com Mon-Fri 9am to 5pm(pst)

The hub shouldn't need a driver, could it be something plugged into the Hub it's not recognizing?
