Great product I've been using my B022-004-R for a couple of years now, and haven't had even a single issue with it. Fully compatible. I have up to 4 computers that I use personally, as well as repairing most of my family and friends computers, and this switch is great for being able to switch computers around on the fly quickly and easily. I usually have 2 ports that I use for my personal computers, and the other two for quick connects for the other computers that I work on, or if I decide to use a third computer for something, and this switch is perfect for that. I would recommend this switch to anyone, and wouldn't hesitate to buy more Tripplite products after the great experience I've had with this one. September 6, 2013
Not USB compatible. This unit is not USB compatible, though the product description says it is. After reading the manual, looking at accessories listed on Tripp Lite's website I couldn't find the pigtail to allow me to plug a USB keyboard and mouse into the switch. I called tech support and after some time the agent told me to (I'm not kidding) search Google for a PS2 to USB converter and buy a third party's adapter. I asked tech support if Tripp Lite sells a USB KVM switch and after some time he admitted that the answer is probably no. The tech support guy was really nice and apologetic so high marks on customer service, but poor marks for this product. December 6, 2012
Works great, NO compatibility problems! I'm always changing my dozen or so computer systems around. This unit works so well, I forget it's there half the time, completely transparent. What more can you ask? I own 2 other Tripplite KVMs, but this 4 port unit beats them hands down. Used it with a dozen different PCs, including an IBM T42 docking station (which my other two KVMs don't work with!), and various kinds of mice, mostly a MS IntelliMouse 1.2a scroll mouse. No problems ever! I haven't tried it, but apparently it even supports USB PCs using different cables and an AC power adapter. Someone mentioned it not working with USB pcs, maybe he forgot the AC adapter? I imagine you can also use a USB keyboard and mouse if you get USB - PS2 adapters, most USB keyboards and mice should maybe support that. The ONE only small quirk, hardly worth mentioning, is sometimes the T42 won't boot, which means the KVM needs resetting. Power off ALL PCs connected so no lights on KVM, then start up again. Has happened about 6 times in the past 6 YEARS, so no sweat! I own 2 other Tripplite KVMs, an 8-port rackmount and a 2-port desktop with audio. Endless problems with both using scroll mice, just can't figure them out. Maybe they're defective, not sure. 5 stars, it works perfect! Why can't everybody make 'em like this......:^) November 4, 2012

[FAQ-892] Is it possible to use a USB keyboard with B020- or B022- KVM Switch models?

Currently these KVM Switches require a PS/2 keyboard. However, if your USB keyboard came with a PS/2 adapter, this may enable it to work with the B020- and B022- models.[Last Updated: Jun 19, 2013]
