Unitek USB Extension Cable with Micro USB Charging Power Port, Portable USB 3.0 4-Port Data Hub Extender Cord for Oculus Sensor, Gaming Controller, Logitech HD Laptop Webcam, Printer, Scanner (4ft)

I picked this up over higher quality hubs because of its portability. It fits nicely into a pocket. But it fried my Logitech C920's USB bus controller and seriously overheated the power cable on an IDLE blu-ray reader before I smelled the smoking hub and unplugged it. This thing is a total piece of junk. It worked fine for a couple weeks, hooked up to a high end PC's NON superspeed port. Pretty much out of nowhere a VRM (i think) overheated and ruined my camera. It could have been sitting there overheating for hours or even days before it finally produced a noticeable odor. I'll have to return the camera now too. I'm not sure what specifically caused it to overheat. The power draw from the devices was completely idle, so I can only guess that a controller in the USB hub failed to recognize the devices were asleep. I'm not going to open it up and look at the PCB inside because I don't want to give the vendor or manufacturer an excuse to deny a return. I've confirmed all the ports on my PC are good. No problems with any other devices or any other hubs (externally powered or not, and with more ports) so I can only conclude that a component in this specific hub was defective. This is apparently a pretty common problem for cheap hubs without AC adapters. But I'm not sure how you could protect your devices. It's not a matter of use case, since the devices I had connected were asleep and do not even draw substantial power when they're fully active. It's difficult for me to prove that there's nothing wrong on my end, but if that is the case, what are the odds that the only VRM producing smoke in my whole setup is this little cheapo hub? And what are the odds that all the other devices I plugged into the same port would have no issues?Even if I'm wrong, why take the risk? Save yourself the hassle and just get a higher quality hub.

Works fine for me. I use it primarily for hardware 'keys' such as Steinberg's dongle for it's professional series of DAW software. I don't have to go behind the racks to get my dongle now if I want to use Cubase Pro 9 on my Macbook Pro instead of sitting in the control room. (For those that don't know - licensed Cubase [and some other software] installations ping the dongle for the license, and if you want to use more than one computer at a time, you have to buy another dongle/license...but if you are using just one instance of Cubase at a time, you just plug the dongle into whatever computer you are using at the time). So, anyway, now the dongle resides in this fine usb hub on the console instead of in the back of the DAW. I have also transferred data between portable hard drives and my main studio computer, with USB 3, and I have not run into any issues with the wireless mouse, wireless keyboard or United Audio Apollo interfaces all using USB 3 and running on a HP Z400 Workstation PC. My wire is about 4 feet long. This does exactly what I want it to so I am happy with it.

First this has the SLOTS correctly oriented so you can put flash drives in without them touching and crowding. Second it's the only one with a long cable allowing it to be accessed from a desktop with the computer below on the floor; no more bending over! 3rd it provides power to the ports allowing my keyboard, mouse and scanner to all work; the cable gives all these enough extra length to be accessible on the desktop with my computer on the floor!!! It just doesn't get any better!HOWEVER, thankfully, MY UNIT HAS the STANDARD USB PLUG for my computer, not a "micro-USB"shown in the review window, that standard USB plug is also shown on this product's sales page. LOL

This product is spotty at best for me. I bought this to make using my graphics tablet and various game controllers more convenient, but it simply refuses to comply. Constantly tells me the USB device is not recognized no matter how many times I've tried reinstalling the drivers. It's not an issue with the devices, as plugging them directly into my computer works just fine. It'll work for a bit if I plug the hub back in with these already plugged into it, but once they are unplugged, the same issues begin again - completely defies the convenience this should have provided. The extra power with the micro USB seemed to make no difference in this occurring. All around has been a total unreliable headache for what I need it for - it feels like I got a defective product. Contacted the manufacturer and haven't heard a single thing back for over a month now. I wish I returned it while I could.

I used this hub for several months. It literally sat in one spot and wasn't moved or had any kind of strain of any kind. It just decided to stop working one day. I tried plugging it into other computers and it just wouldn't work. I would maybe use this thing once or twice a week for a few minutes at a time. So disappointed. Note-to-self, spend a little more on a better hub.

I bought 2 of these, they work fine with regular flash drives, but with the new usb3 high storage like 128gb or 64gb, Samsung and SanDisk it desconects on-off-on-off, sometimes pulling the drives a bit out works. Same in both units.

My computer is on the floor under my desk so getting to the USB ports is a chore; I wanted this with a long enough cable to run up the back to my desk surface - it's great for that! Nice to have multiple ports without bending over. Since I'm a long-time tech I'm always plugging and unplugging USB devices. This solves the problem!

This is the first bargain USB 3 hub I've found in four years of searching that doesn't randomly disconnect/reconnect after a few days of use.I very much like this and will probably be buying one or two more for my other PC.
