2 out of 5 eggskinda works - would not actually recommend it though.

Pros: works well to connect and run all of the multiple functions on my HP 2820 color laserjet/scanner.

Cons: did not work to access my Formlabs Form1+ printer, nor access a simple USB disk remotely.

Other Thoughts: Got in touch with TrippLite, and they blamed Formlabs. Formlabs blamed TrippLite. Typical male cowfeces. In the end, it was probably more Microsoft's problem. They have a generic USB driver (WinUSB) that developers can use, but it's junk. That's what Formlabs (and no doubt many other products) used. TripLite's extender has no clue how to deal with this. Not sure any of the available extenders are worth much actually.

1 out of 5 eggsOnly works in Windows... if you can manage to log in.

Pros: Once the drivers are installed, and you're logged into Windows, it works fine.

Cons: The extender does not work outside of Windows. It doesn't work in the BIOS screen or in the boot process. But what makes it nearly useless is that you can't use a keyboard with it to log into Windows, nor can you use a mouse on the login screen.

Other Thoughts: If you are planning to use this for a device other than a mouse or keyboard, and only intend to use it within the Windows environment, then it should work fine for you. Using it with a keyboard and mouse is all but useless, and I'm surprised that they aren't as up-front about this flaw.

Manufacturer Response:

We apologize for the experience you have had with the B203-104. What you have described is a limitation of the product. If you are looking for alternative models that would be more appropriate for the application you are describing, we would recommend the B203-104-PNP or the U224-4R4-R USB 1.1. We encourage you to reach out to our Chicago-based Presales Applications Team at 773-869-1773 (M-F 8AM-6PM Central) or email to discuss your application in detail and determine what the most appropriate solution would be.

4 out of 5 eggsGreat alternative

Pros: I was skeptical buying this product. Havent had the best luck with Tripp Lite stuff. Also all USB 2.0 extenders I looked at were $400 and up. Why was this one cheap? Well I can see why, its not flashy, its heavy and bulky. But who cares? It extends my USB 2.0 over CAT 6 just fine. Transfer speeds are acceptable and does everything I expected. Important note, its not natively supported by the OS, you need to install drivers, for my tricaster 8000, this was a bit of a bummer, but it still works. Occasionally 1 USB port stops working, but a quick power reset fixes that. Worth the $300 savings all day. Ready to buy another.

Cons: As mentioned, needs drivers, 1 USB port is flakey.

Other Thoughts: Don't drop 589.00 on the Geffen USB tools unless you like to waste money. This does the same thing for $300 less.
