If you are asking can it be used as a conroller to interface with the powerline like a PLC or PLM, no.

In my discussion with homeseer, where I was having PLM hanging issues as well, they pointed out that I had checked in device manager under "USB controllers" to allow computer to manage power to these devices. I uchecked and that made it so I could go a couple of days before the 2412U hangs and freezes PH, with corresponding "cannot communicate on com3" when restarting PH. I will try powered USB hub.
I am on my second 2412U, my third computer, (dell opti 270) and second HA software. (I tried homeseer with same results". So its definetly not the HA software, but the SH hardware. Does moving to a serial interface fix these issues? I've about had it with this freezing issue. There is no hope of selling this to other people with this poor state of reliability. Thanks to everyone who has commented on this issue and the PH community in general. Drew.

I've been running with a Serial PLM since PH2 Beta (not the Alpha) came out and have never had a PLM hangup that I can remember. Others seem to run okay with a USB PLM. May well be the type of USB connection on a given PC.
Hopefully others will jump in with their USB and Serial PLM experiences.

As I have said before I run a serial PLM with a USB to serial adapter. Mine is rock solid like Lee’s, BUT I have seen PH lockup when there has been a loss of communications between PH and the PLM. PH seems to go into endless error recovery although I don’t think it is the same problem. The problem Drew is having sounds external to the native computer systems. Either the same software is loaded on all the systems and is causing a glitch as in a driver is replacing Smarthome drivers, or there is something on the powerline which is unlikely.

I have a serial PLM (no usb adapter). I use an 8 port serial card. My PLM has been solid. All I can say is that in general, I like serial devices over usb type devices...to me, there seems less to go wrong.
My usb CID modem sometimes gets flaky, but I think it might be because of a loose fitting usb connection...

My battle seems to be over. I returned my second 2412U for a 2412S (serial) and have been running now for a week without a crash.
I went through two usb (2412U's) and tried a powered USB hub with no luck. Thankfully that frustration is now over - I even had a spare serial port so did not need to buy anything else. Keeping fingers crossed but seems like I have a working and stable Insteon system again.
The 2412U seems to work for some but if you have a choice (you have an open serial port), I'd stay away from it and stick with the serial version. I think it (usb version) has a serious design flaw (not sure if SM will admit and fix it or not).
Thanks everyone for the input and help on this. It was your comments on the serial version that led me to try it and finally resolve a year of Insteon frustration (which started with a failing 2414U, two 2412S, usb hub, lots shipping costs, etc.).
Happy 2010!

Yep welcome to the club.  I'm glad the saga is over. Now onto bigger and better adventures.

Interesting information on this forum. I recently purchased PH2, 2414U and about 12 Insteon devices. I eventually plan to expand my entire house and office with these devices. IF I CAN GET IT TO WORK. I have spent hours before I came across this forum. It makes sense about the USB hub and I will try that. I also have another question. I currently have my 2414U plugged into an AC outlet next to my computer. The other recepticle has an APC 1400 UPS plugged into it. I could not get PH2 to discover any of the three devices currently attached to that phase. When I moved the 2414U to another outlet (on the same phase) outside the room, it did discover, but I have freezing problems and all kind of unknown devices linked. Any ideas?
Thanks Anthony

A UPS is often a source of Insteon signal attenuation. The power supply does a good job of cleaning up the powerline so noise does not make it through the UPS. Unfortunately the Insteon signal looks like noise. The PC power supply can have the same affect. Generally a Smarthome FilterLinc between the UPS and the outlet solves the problem. It is a good idea to put all the peripherals on the FilterLinc so you may need a 10A version. You can temporarily put the 2414U on an extension cord and plug it into a circuit in another room which is generally a different circuit and far enough away to eliminate the problem. The sales page for the 2414 recommends the use of a FilterLinc.
Not sure this will resolve the freezing problem. That may be a USB related problem rather than a powerline noise problem.

The other thing that may explain the strange links is that at times devices are received with active links already in the device. You will find several posts about this on the Smarthome forum. It is a good idea to factory reset any new device before beginning to use.

I found this thread and a similar one from 2007 expressing the same problem. In the previous one Dave mentions that he would try a fix in the next version, but I guess that did not work. I've had problems with freezing off and on - requires a cpu reboot to fix - maybe once a month in the past, but have seen several of these in the last few weeks. In my case I lose both the USB serial port and the Com 1 serial port. I am using Eltima Serial port splitter software, so my com1 is a virtual port.
At first I thought the freezing were occurring because of the macros I had that sent data to the com1 port in response to a keypad/paddle press, but I tried a "rats on speed" test (rapidly toggling the keypad button), and PH performed beautifully will all serial commands getting to the controller just fine.
So I'm giving up on my USB PLM and swapping it for the serial version (dual band). Just thought I would check to make sure this is still the prevailing wisdom on this problem - has it solved the PH freezes for those of you who had this issue? Wish I had read this thread before I got the USB version.
