Customer Reviews

Works with Linux, and works great!I only unpacked it today, but it works great out of the box and has a sturdy construction. I was hesitant when picking a KVM but from everything I read about this one, it seemed like it would fit the bill. I have one Windows box, and 3 CentOS boxes all connected and can switch through them. I didn't even have to replace my old Logitech K260 Keyboard mouse combo. The KVM just works, much better than some I have dealt with in the past.The biggest con is that the power supply for the USB hub isn't part of the package, but that won't be hard to find or pricey. Great product. I'll update on another date if anything changes, but I don't suspect that it will. 5Quality, features, and outstanding support: A KVM you will want to consider. (Not a sales pitch).When purchasing a product, you want to consider not only the features, look, and cost of that product. You also want to consider what support you will receive after the purchase and perhaps in advance of the purchase. I want to mention this first because it ties into why I purchased the SV431USBDDM. I wanted a KVM that would allow me to just use the USB functionality since I do not need the video switching function. I contacted Startech and they answered all of my questions and took the time necessary to fully understand my needs. This makes a big difference and they made it very clear that if I had any issues at all I should call. The customer service person even took time to describe the connections and layout of the device. So, the SV431USBDDM itself. It is a very well constructed and nice looking device. I am a Mac user and have three machines connected to the KVM and I have not experienced any difficulties with any USB functionality. Switching is fast, including devices connected to the two ports such as a USB microphone. The hotkey switching works perfectly and is very easy to change from the default shift key (double tap to activate KVM functions/switching consoles). For those with visual impairments, there is a beep (off by default) which can indicate when you are switching from one machine to another. Maybe there is a better KVM out there, but for what I needed this is perfect. I did not want audio and the video is not important to me. If you are looking for a high-quality KVM with excellent support, then I highly recommend Startech's products and the SV431USBDDM. 5easy to setup and rugged constructionThis is the best and longest lasting KVM I have purchased. I have been using one for over 5 years and had no problem whatsoever. Those who complain that it does not work on a Mac should read up on USB technology. A lot of old mac models do not provide a 5v power on any USB port even the ones directly connected to the tower. That is the fault of Apple not Startech. I use a generic DC power supply from Radioshack. The person who claims that a 2amp 5v DC block is hard to find did not do enough research. It is readily available at Radioshack stores.The best part I like about this KVM is that it does not limit the number of consecutive key repeat strokes unlike other KVM. Try and hold down a key on a Belkin or other brand KVM and the keypress will stop after a few dozen repeats. That is bad for gaming where you have to depress a key for a long time (especially for FPS games). This KVM also recognizes higher resolution displays 1900x1200 and up. Other KVM will max out at 1600x1200. 5Works great and allows me to finally use all of my ...Works great and allows me to finally use all of my devices easily. The keyboard switching works perfectly as does the video switching. In comparison to the cheap KVM devices I have used in the past the difference is night and day. It costs a lot more than the cheap KVMs, but you get what you pay for. In particular, the KM emulation (basically makes all devices think that a keyboard/mouse is always plugged in, regardless of which device is in control) is a lifesaver when working with servers. No more issues with restarting devices and constant reinstallation of drivers or driver warnings. 5Great SwitchI do not use the video portion of this switch as I have a need to see all PC monitors at all times so have 7 monitors on my desk. The use of the switch for mouse and keyboard were my chief reason for purchasing this switch. It switches between PC's in 1 to 2 seconds every time and I switch 20-30 times a day without a hitch. I have found that the built in USB hub also is very useful and a plus ... I switch put a USB hard drive on the hub and it takes about 20 - 30 seconds for the PC to recognize the drive after I switch but is great for moving files between PC's as they are on different networks and I cannot transfer between them over my network connections. I have 1 PC running XP, 2 running Win7 and one with Win8.1. Although I can not tell anybody how the video portion works if you have a need to switch keyboard and mouse between multiple PC's this is a great unit. 5I have enjoyed thisI have 3 computers hooked up to one Monitor making it very easy to switch from one to another. I wish I could figure out how to change computers without needing to safely remove my external drives. Other than that it is great. 5Really easy to set up and use; Great Design, Quality and PriceTop quality design, really easy to use, and small and compact. I didn't use/need tech support so no rating on that. Only thing to know is that the special cables needed are not included with the product but are also available on Amazon and for a really good price. 5Outstand USB KVM valueI wanted to add a USB KVM switch to my computer network, replacing a PS/2 KVM switch. One key desire was a rack mounted switch to clean up the work surface. I researched various switches and selected the StarTech KVM since the multi-star reviews were positive, and the few 1 and 2 stars were focusing on the lack of some features those people needed. Since I didn't need those features (hot switching via keyboard) the StarTech was my choice...and a great choice it was.Construction wise it is rock solid...heavy gauge metal - not plastic. The optional 1U rack mount kit worked perfectly. Assembly and setup was smooth as silk.A few items of note:This KVM switch uses standard video and USB cabling between the switch and the computers...The USB cable is A-B type connectors, and the VGA is standard 15-pin M-F cable. You can buy the StarTech cable sets (6' worked well in my rack) but you can also use your own cables. The StarTech cable sets are heavy duty and somewhat stiff - so if you need flexibility or less than 6' (such as a desktop) then roll your own cables.Also, the optional power supply is to power the USB hub (USB 2) if you're going to switch USP peripherals between computers/servers other than the keyboard and mouse.For me, this was a great find and fulfilled a desire to neaten up my basement rack.UPDATE: Decided to order a second StarTech 4 port switch especially since it didn't require any special cables...just an A-B USB cable and a M-F VGA cable. In this case, a non-rack application, using shorter 3 foot cables. I'm very pleased!UPDATE2: Continue to be very satisfied with this KVM switch and highly recommend it. 5Easiest KVM I've usedAt first I was confused as to why there was no power supply included in the box but then I realized it was powered by the computer itself. This was probably the easiest and most affordable KVM I've used. Works great. 5Expensive once you add up the price of required "accessories"Half a star off for cost. The problem is this requires cables to work, and maybe a power supply, plus ears if you want to mount it in a rack. The good of this is you can choose your cable length: 6 foot (p/n SVUSB2N1_6), 10-foot (p/n SVUSB2N1_10), or 15-foot (p/n SVUSB2N1_15). Other brands come with attached cables--lower cost, but you're stuck with a fixed length.This unit contains a four-port hub, which means you can plug in more than just a keyboard and mouse. If all you use it for is a keyboard and mouse then you probably don't need to add a power supply (p/n SVUSBPOWER). However if you add other accessories that get their power from the USB connection, then get a power supply. Any 5 volt DC regulated power supply will work. That StarTech supply is 2 amps, their instruction booklet mentions 1 amp, and I'm using an old Cisco line-lump style supply that's 2.5 amps. What matters is the supply puts out enough amps to run your scanner, camera, hard disk, or whatever extra you plug in. What's nonnegotiable: 5 volts DC regulated, connector diameter of 5.5 mm, and that it's positive center (all modern wall warts are positive center).Finally are the rack-mount ears (p/n SV431RACK). I'm not fond of StarTech's split lacing bar (it's too fat) and although my target machines are in a rack, I put the switch on my desk and so didn't bother to buy ears.Another half star off because it's persnickety when you switch from machine to machine--for best results you must wait a few seconds before using keyboard or mouse. Think of it this way. You have a hub plugged into your PC with a keyboard and mouse plugged into the hub. You yank the USB cable out of that PC and plug it into another. It'll take a few seconds for the new PC to recognize the keyboard and mouse, wake up the proper drivers, etc.I've had an 8-port StarTech PS-2 KVM switch for about 12 years. What a colossal pain PS-2 was. You cannot hot-plug it like you can USB, which meant StarTech had to put a tiny processor on each port to fake out the PC and fool it into thinking your PS-2 mouse and keyboard always remained plugged in. This led to tons of problems if the tiny processor got mixed up (CTRL key stuck on, or whatever). They didn't have a clean way to reset those processors, and power-up of the switch and the servers it connected to required a strict sequence. Power cycling servers to get your KVM switch un-confused is unacceptable. This new "yank out the USB cable and plug it into the next machine" is an advantage over power cycling.Dumb StarTech + smart USB specification is an acceptable compromise, even if it's a pain in the butt. I put a sticker on the front of my new KVM switch that reads, "Count to 5 S-L-O-W-L-Y". My USB mouse was failing and the count trick worked, even when the mouse got so bad it ceased to work when plugged directly into a computer's USB port (got a new mouse, which works much better). Oh, and I scrapped my old PS-2 KVM switch.To make this work properly you need to set a couple of things in your BIOS. StarTech details this in their little manual.Positives:Extremely rugged.StarTech really gets their VGA right (their specs claim 1920 x 1440) and they have great cables so I suspect 15-foot cables would still look awesome.Four-port hub rather than just a two-port hub like everyone else. It'd be terrific if you had a scanner or something. I've successfully used thumb drives (beats crawling around inside my rack with a flashlight to find the USB port on the back of a server). And I tried a DVD drive. The DVD drive works fine once the server is booted, but it didn't work to boot off the DVD (bummer, but it kinda makes sense). Because of the tight spacing of the cables and the location of the monitor's VGA cable two of the USB ports are harder to reach (I use those for the keyboard and mouse).Important note about the USB hub: Because the switching technique is "yank and plug" it's critical that you dismount your USB accessories *before* you switch. The keyboard and mouse are okay (don't forget the BIOS setting), and there's a setting in Windows so you can yank thumb drives without first ejecting them (must eject on Mac), but everything else needs to dismount.Finally, there is no traditional on-screen-display to facilitate switching with the keyboard. According to the manual there are some new keyboard commands, but as I have this switch on my desk I haven't bothered to learn the new commands and just push the buttons instead. Oh, and for my new servers I'm going with IPMI v2, which is KVM and remote media over a dedicated Ethernet port (works at the BIOS level). Someday I'll retire this switch.That's about it. The StarTech SV431USB isn't perfect, but pretty darn good for what it is. 4
