Dongle compatibility

[Ted Lechman]

I've discovered incompatability between the ModelSim dongle and
certain notebook computer's printer ports: They are

1. Toshiba Satellite S150s (I would suspect all Satellites). I've
experienced this personally. I had to returnthis notebook and get a
CompaqPresario 2500 in its place to make sure the dongle works.
2. Sony notebooks ( my local distributor has had this problem).

The rumor is that its a voltage incompatabilty issue, but I'm not
sure.

Did you verify that you had your port settings correct in the
laptop's BIOS?

Unfortunately, parallel and serial port dongles aren't really
compatible with *anything*. They inevitably work by stealing power
from the interface they're plugged into, and it's a matter of pure
chance whether that will work at all, since the PC isn't obliged to
provide power in this way. Not surprisingly, laptops are frequently
problematic in this respect.

I would have thought a competent company should be able to supply a
USB dongle, which may legally negotiate to draw up to 500mA from the
port.

Alternatively, you might try wiring in an external PSU of some sort to
supply the dongle? Ugly, but it might get you going.

Personally, I avoid dongles like the plague they are, but I realise
there isn't always a credible alternative.

Yes, of course - I spent the entire 14 day return period doing nothing else.

Well, had to ask. But 14 days? This should have taken about 1 hour
max, assuming you tried ECP and bi-directional, and didn't know how to
get into your bios, and had to search around for the book...
