Review on 💪 Enhanced Plugable USB 2.0 7-Port High Speed Hub - Boosted with 15W Power Adapter by Joshua Follansbee

Arkview Aquagate and Replacement 7-Port USB 2.0 Hub Overview 7 Model USB2-HUB-AG7 SN 9901002A03183 This information is located on the bottom of the case. The test report is written for both products, as they only differ in two rather minor aspects. They have the same form factor, contain the same PC card, and use the same NEC hub chips. They have different wattage power supplies, and the plug-in has a diode that prevents the 5 volts on the hub from being sent back to the main computer. I didn't find any other differences. Hubs have hub chips NEC stamped upd720113 and registered as NEC chips in numbering at launch. This doesn't prove they're real, but they probably are. In any case, they work very well. If they are fakes, they are good fakes at the moment. However, everything can change. It's easy to open the case and look at the chips. Inexpensive consumer devices like this are often the target of fraudulent sales replacing another product that doesn't even look like the picture. If you receive such an item, you should immediately leave stinging negative comments about the seller and request a refund from Revain. I received the Arkview Aquagate from a seller who claimed to have sent me a device with a pluggable USB 7 port. The Arkview power supply is 2 amps versus 3 for the pluggable. This means that Arkview 4 devices such as B. Bus-powered hard drives at full power, each using its full quota of 0.5 amps. Plugable can power up to 6 devices. If a 2 amp power supply will meet your power needs, you can use Arkview and save a few bucks. If you need more power later, you can easily replace the power supply with more power. USB 2 hub chips are complex processors, unlike the USB 1.1 hub chips that preceded them. A relatively unknown fact is that once a hub is connected and a high-speed connection is negotiated, the speed is locked at that level. To be compatible with older full-speed USB devices (and most audio devices use full speed), the hub must connect to the device at full speed and then use what is known as "split transactions" to communicate with the host processor to communicate. . Transaction splitting is done at high speed, which allows many full and low speed devices to be connected without significantly slowing down high speed transfers with things like a hard drive. TT) and usually has one for each four-port hub chip. If more than one full-speed or low-speed USB device is connected to the same hub, the translator must service both devices individually. When multiple full-speed devices require the best performance, it is important that each is connected to its own USB 2.0 hub so that it has a dedicated transaction converter. to adjacent port connectors since you are most likely plugging both devices into the same hub chip, which will then use its TT for both devices. Attach them to the hub as much as possible and you'll be fine. Sure, it's best to dedicate a 4-port 2.0 hub to each audio device. The advantage of NEC (now Renesas) chips is that they are well designed and able to maintain the connection without accidental breaks. High-speed USB sends 480 million relatively small signals per second over a cheap set of cables. If something disrupts this flow, the host processor restarts the hub (and all devices on it), renumbers, and then reconnects everything. This can take a few seconds and cause all sorts of problems when data is being transferred to the hard drive at high speed. Cheap hubs tend to share ICs, which I find problematic. I connect my hubs to an inexpensive USB 4-port mechanical switch that allows me to switch between any of the four computers. I have no problem with the switch with these hubs. When using a switch with cheap no-name hubs, I get spontaneous shutdowns and very unreliable performance. The mechanical switch degrades the signal as it is routed to the PC card traces and then back to the other connector. This setup requires the best hub chip. Check ALL ports when you first receive the device. I found a few dead ports on one of mine and sent it back for a replacement. Test each port with a keyboard or mouse, and then with a high-speed device that consumes full power, such as a laptop. B. a portable hard drive. Look at the label of the power adapter and make sure it meets your expectations (2 amps or 3.5 amps depending on the model). Plugable is sold by Plugable for $20. As mentioned above, the main difference from Arkview is the smaller power supply. Normally it shouldn't matter as most don't try to run more than 4 devices at full power at the same time from a single hub. I don't have a huge preference for the form factor. There are situations where it is more convenient to have all of the device's ports on the front, while the host port and power connector are on the back. But I also like two vertical ports and a combination of front and rear horizontal ports. To me this is cheating. In summary, I think the $14 Arkview Aquagate hub is a very good buy as it is well made with quality parts. If you're going to use USB with some kind of mechanical host switching mechanism, I recommend any of these hubs unreservedly. Plugable has a great return policy and you might find it worth the extra few bucks. If you tested your device on arrival and purchased free shipping with Revain, you can return any defective device within 30 days.
