I was wondering if it is possible to have two [or more] ULINK devices running on the same PC ?
I 'expect' [hope] to be able to launch two Keil IDE's and run two Target Boards using two ULINK devices.
Is that possible?

I had problems using just one uLink on my Toshiba SatellitePro laptop: http://www.keil.com/forum/docs/thread14502.asp
I remain unconvinced as to whether it was the PC or the uLink (or its drivers) at fault...
Since my origional post, I've had to drive down to the Department of Motor Vehicles, twice: 13 miles each way in traffic.
Hence my long durations between posts. TWICE !! (Both of those were because of the STUPID DMV People not getting their ducks in a row: my wife had to sit there for three hours, and I needed to sign two documents--of which I had previously been to the DMV to sign a bunch of documents before! Oh, yeah... and here's another one--drive down. Ah, another! drive back)
Anywho, I usually suspect the USB drivers that are sold as add-on cards to a PC. I've seen some that don't/won't handle the 500mA requirement: I've reversed engineered the devices (e.g. looked at the parts) and it turns out that they cannot supply 500mA at all.
With such flakey electronics, it wouldn't surprise me if these cards had flakey drivers.
But, Andy, your point is well taken.
P.S. Oh, I can hardly wait for Obambi-Care to kick in. </rant>
I think there's some ambiguity as to whether you're using "drivers" in the hardware or software sense there...
Captain,
The problems I mentioned are strange, and apply only to design surrounding the LPC2478 chip - a similar one that uses a LPC1768 has no problems at all. It must be a routing problem of some kind (it has nothing to do with the double chip design - it happens on another product using a single chip) - often, if a program is stepped through control is lost - it can also happen if the debugger is started. It is very disturbing, but related directly to our hardware. The good news is that the product(s) are almost done...! No setting in uv4 seems to alleviate the situation. In the future, we'll probably mainly use Cortex based chips, but first NXP have to release the Cortex M3 equivalent of the LPC2478 (LCD controller)...!
