Does what is supposed to

By: TheMadOne! on 05/16/2016

It works, but had initial problems with installing the drivers & such on the included media, few little PC bugs. Had to do some research on the "Error 1603: A fatal error occurred during installation" problem. Solved it with a little cleaning up, resetting & restarting, but still a PIA. Windows 10 Pro System.. the old Windows "Plug & Pray" scenarios are still just a prevalent on the latest greatest Windows OS as they have been since I started with Windows 95 all those years ago!!

My issues with this product

By: StarFishMan on 04/23/2014

I have other USB hubs from CoolGear and they are great. Pricey but great industrial strength hubs. In this case this device has not worked out for me. My goal was to use this with several USB devices for example USB to RS-232 adapters. And also some higher end USB cameras. Unfortunately in my case I have not been successful using any make/model USB to RS-232 adaptor (and the manufacturer states these devices are not supported). Nor have my cameras worked either. Often times I get a the BSOD (Blue screen of death) trying to connect to this device. Simply put this product is not for me!However, it works great with memory sticks, USB thumb drives, I have to assume USB printers too. But, outside of anything but basic USB devices like these I have found it doesn't foot the bill for me. I was surprised out how few of the devices I tried would actual work but I am not your average or normal user either.Again the company puts out great products for the most part so this is not a reflection on them in anyway. Just this particular product was far too limited for my applications.

Conveniently allows VMs to have USB support from anywhere.

By: SSDguy on 11/03/2013

Allows you to have USB support from your virtual machines (I run VMware ESXi Hypervisor), from anywhere in your home network.So in other words, if your hypervisor machine is buried in your basement, you can have this unit up in your office, and have devices like scanners, printers, flash drives etc, plugged in at your desk and access your VM over remote desktop on your laptop to make it seem like that pc is right next to you.

Drivers crash often

By: Lowenna on 05/02/2013

When it works, it works well, hence giving 2 stars. Streaming audio from a VM under Hyper-V just fine, as the old Digi USB 1.1 USB-Over-IP box I had just couldn't cope with the throughput. However, the drivers for this device are dreadful. Expect daily crashes for no apparent reason, and almost always crashes when unplugging a device. Cannot find any online drivers which are newer. Running Windows 7 32-bit. If the drivers were stable, this would get 5 stars.Driver version as came with mini-CD in the box: "Nu (Network USB) USB Server Version 8 July-13-2011. PSM DLL Version December-08-2008. Copyright 2011 USB Server. [...]"-----After writing the review above, I did some more searching. It seems there are later drivers and firmware available if you know where to look. [...] Looks like you need the E2868/E3868 firmware, which as of writing, latest was 2.055, 14th June 2012. The unit was shipped with firmware version 2.032. The latest Windows 7 32-bit update (Referred to as WHQL 11.1027.0050 on that site) moved up to USB Server Version April 09 2012. PSM DLL Version, December 8-2008 (same date as!). There are also beta WIndows 8 drivers available. Can't comment on how much more stable this will be yet...
