1.0 out of 5 stars Mac Snow-Leopard WARNING
Reviewed in the United States on August 30, 2010

I have had a few of these since they were first released. However, Keyspan (now Trip-Lite) seems to have lost interest in continuing support - particularly for the Mac and Snow-Leopard. While the 10.5.x drivers might work on 10.6.0 - 10.6.3, they DO NOT WORK ON 10.6.4!!! Some people have also reported problems on 10.3.9, so some issues may be related to the specific device. However, on 10.6.4 although the USB devices show up in the Keyspan USB server management software window, they cannot actually be used.

I called Keyspan and they verified that 10.6 is not supported, that they have no plans to support it and that they are not even sure if they will continue to produce this product.

YOU HAVE BEEN WARNED.

2.0 out of 5 stars Not Working with Canon Multifunction (MF Series), Causes BSOD
Reviewed in the United States on August 9, 2007

You have to disable ALL firewalls (both Windows or any 3rd party firewalls) to be able to install the server correctly. It shouldn't be necessary (I remember several other software/hardware would just trigger firewall dialog automatically when they are installed, and you just click "Yes" or "Authorize"). You have to open some ports on your firewalls (both TCP and UDP). Not too convenient in my opinion.

Once it's installed, it will see the attached device.

For my case, I wanted to use Canon MF5550 (multifunction Printer/Copier/Scanner/Fax). It detects as soon as I plugged it in, but when I install the drivers, it gives me a BSOD. Not sure whether it is my Windows, or my printer. But it sure is not pleasant. Eventually, I'm unable to install the printer on my PC.

I then tried to install the server and printer on my laptop. It installs fine now (both the server and the printer). But the printer keeps saying "Offline". Usually, I just need to unplug the printer and plug it back so it will be "Ready". It doesn't work this time (I have even also set the server to "Auto-connect" to the printer, still to no avail. Power off the printer and power it back on doesn't do anything as well. I guess it's my printer..

So, my suggestion, if you have the same Canon Multifunction (MF series), I'm afraid it won't work with this server. Not sure with other multifunctions..

3.0 out of 5 stars A word of caution

This is a nice device so long as you have a firewall you can manage. You MUST be able to manage your firewall if you use one. Otherwise don't be surprised to find this has no value to you. I bought this to use my home printer and network with my company PC. The firewall prevents the company PC from even seeing this device. Works great on the home PC after a few easy steps learning how to manage the firewall. Unfortunately, that is not why I bought it. The information on Amazon did not have this limtation. Also, the Amazon information does not indicate you must release USB devices from one PC before you can connect with another. If you can manage these issues, this is a slick device.

Hi. I find this product to be very good, but also could find features that need improvement.

First of all, I bought this stuff last year and returned it because our laptops couldn't recognize it in the netwrok. Later, I remembered that XP SP2 patches had been installed on our machines just before I tried to use the keyspan server. Since SP2 automatically turns on XP's firewall function, our laptops perhaps failed to recognize the USB server because of this. I wasn't wrong. When I re-bought and installed the USB server later, I reconfigured the security options of XP on my laptops so that the firewall doesn't block the port used by USB Server. Voila, I could see the list of the USB equipments connected to this little gizmo.

Once I configured it right, I found out that this thing is very convenient for just everything. Here are my equipments attached to it: a CDRW, an FDD, an external HDD, and a printer. All these gadgets are working seamlessly now.

However, besides the above configuration problem, I have experienced one or two problems so far. (If I haven't, I would've given 5 stars to this stuff.) When my EPSON 5200 all-in-one died of clogging problem and I purchased for Lexmark 5270, the autoconnect function of Keyspan USB Server didn't work with the new all-in-one very well. I strongly suspect that it's because Lexmark's poor device driver; however, it's true that Keyspan USB server is incompatible with some all-in-ones. I returned Lexmark 5270 and bought epson stylus c82. As a matter of fact, I believe that usually this goes along with epson printers and all-in-ones.

Bottom line: I recomment this machine to anyone who wants more than one PC and USB equipments. However, you need to check your PCs' firewall configuration and, when you buy this stuff or buy another USB equipment, keep your receipt for a week or two. You may have to return this stuff or, if you already have one, your new USB gizmo because of compatibility issues.
