Question: Is there a keyboard HotKey to toggle between the two USB ports on this switch?
Document: Look folks, I'm going to give it to you straight. If you want a USB 3.0 switch to toggle the connected devices between two computers this just flat out works. This thing is tiny.Now, there are two design improvements that the manufacturer could do to make this crazy awesome.1. Those lights are WAY bright! Dim them down a bit, yikes.2.
This works well as a switch. I have it plugged in to a 3.0 USB hub. It works nearly every time I use it. I use the switch daily about 10-15 times. Perhaps once a week I have to restart the USB hub to get the keyboard and mouse to switch.
The SIIG USB switch does exactly what I was hoping it would. I'm currently using it to easily switch all my peripherals (Razer Mouse, Mechanical Keyboard, USB headset, External HDD, Bluetooth Adapter, HP printer, and Webcam) from my personal computer to my work laptop without having to unplug anything.
I use my work laptop and my home desktop computers with the same monitor, keyboard and mouse. My monitor will switch between inputs with the touch of a button and the KVM switches I've tried all had less than acceptable video. The Desktop has USB 3.0 but the laptop has only 2.0, but the switch works with both. I have a 7 port 3.0 hub with the keyboard, mouse, scanner, printer and a 3.0 thumb drive to transfer files between computers.
If you have a USB 3.0 device you need to switch between two computers, this is the way to go...Works perfect and switches instantly. I use a 1T WD PASSPORT to transfer files between two PC's and it is fast! Love it!
Works as advertised. Beats swapping cables manually. If you daisy-chain two of them you then have a nice 3 to 1 switch. Odd how there are so few USB 3.0 switches on the market. Now for the caveat ...These are unpowered units so note the following, taken from personal experience.1.
For two computers sharing peripheral devices connected by daisy chain USB.Purchasing a new computer often presents one with the old machine side by side with the new machine and there is a transition period between using only the old machine to only using the new machine. THIS is the time that having one of these USB Switches can be vital. With the click of a button the complete USB daisy chain responds to either one computer or the other. This Switch is great !
My rating reflects the misleading product description, which claims that this switch works with external hard drives (i.e., devices that can really benefit from 5GB/s data transfer rates). I purchased the switch to share a Western Digital My Passport hard drive between two computers and it failed. On the other hand, the switch seems to work with devices such as webcams, camcorders, video cameras, but those devices do not really take advantage of USB 3.0 superspeed, do they?
I'm using this to share a keyboard, mouse, printer and external storage among 2 PC's that both support USB 3.0, and it works great.Easy to install, and super easy to use.Highly recommended
I've been using this to share a keyboard, mouse, and USB digital audio converter between a Mac and a PC. It works perfectly with my monitor's built-in USB hub. I've tried it with a USB 3.0 hub, and there were issues, but I think that that was because the hub was going into a power-saving mode.
Answer: I don't think so. There is no driver to be installed. The only way to change between the two USB is pressing the blue buttons.
