SIIG USB 3.0 Active Repeater Cable 33 Feet, USB Extension Cable for USB Flash Drive, Hard Drive, VR, Printer, Camera (JU-CB0611-S1) 10 Meters USB 3.0

Everything is good, worked as expected, bur we bought more powerful external adapter (2 Ah) as we have connected a usb 3.0 device with high power consuption.

I can extend a webcam with this cable. Other cables failed to give the webcam enough power, bu this one works even without the external power supply.

I bought this cable after seeing how successful Chuck Astrophotography on YouTube had been with two 20m SIIG cables. I connect to a remote Telescope with a Usb 3 router. It supports two ZWO cameras a SkyWatcher mount, a filter wheel and an electric focuser. The first time it worked perfectly fine, not one single issue but the second night out I had some difficulty first with the cameras then the focuser, then the auto-guiding. Astronomy is like this, so hoping it was just a trying night. I perservered and got everything I needed in retrospect. The alternative is to go wireless with an ZWO ASIAIR PLUS, but heyho, more cost! Thanks for the other candid reviews highlighting various problems, like the fragile powered usb connector! 20/3/22

My goal in purchasing this cable was to wrap it together with a 20 meter optical DisplayPort cable to make a super long extension for my Valve Index VR headset. The end result was unsatisfactory. I am able to use the headset with no lag, while on a different floor of the house from my PC, but the passthrough cameras do not work. If you're thinking of buying this cable you probably already know most of what you need to know about it, so here are some things I would have liked to know ahead of time: 1. There are 'repeaters', little AA battery sized bumps, every 5 meters or so. 3 in total on a 20M cable. Not an issue for me, but if you were trying to run this through a wall or a drilled hole you should make sure this is taken into account. Also, while the edges of them are round, there is a potential for them to snag. My cable is wrapped with another one inside a nylon mesh tube, so that takes care of this issue. 2. The cable does come with a power adapter. Didn't see that mentioned but I didn't look very hard and was expecting to have to use an adapter I already had. There was one in the box. Cool. 3. You do need the power adapter connected in order to get USB 3.0 speeds. 4. You may have to play with it a bit. My initial setup procedure was to plug the male end of the USB cable into the computer, secure the slack, then unspool the cable to where it needed to go and plug the rest of the stuff in. This resulted in the cameras not working. After plugging and unplugging both ends and doing various software resets, I found success a single time by rebooting my computer with everything connected. After that it detected just like I was in front of the PC. After that the cameras never worked again. So be prepared to mess with it, it's not a regular passive extension cable. Overall I definitely give it 4/5 stars. VR headsets are weird creatures, and with both bandwidth and latency sensitivity being very high I'm not that surprised it's tough to find a working solution.

It's working like a charm. So far it has not missed a beat.
