<i> &gt; Looks like you have the Mac version of the QuickCam, which is</i><br>
<i> &gt; indeed a serial device, of sorts. The qcam driver is for the PC</i><br>
<i> &gt; version which is a parallel port device, and the driver directly</i><br>
<i> &gt; flips bits on the parallel port, which is why it needs the port</i><br>
<i> &gt; address. So, I'd say you're kind of out of luck from that</i><br>
<i> &gt; perspective.</i><br>
<p>
<i> &gt;&gt; From what I remember, the Mac version used a special synchronous</i><br>
<i> &gt; feature of the Mac serial port, whereby the Mac could clock data</i><br>
<i> &gt; in/out of the port at some high rate, like 1Mbps or so, which is</i><br>
<i> &gt; why the Mac version couldn't be used on a PC (and hence no</i><br>
<i> &gt; x86-linux driver for the Mac version, that I ever heard of).</i><br>
<p>
True, I have looked high and wide for other drivers and to no<br>
avail. And I am not the only one looking...<br>
<p>
Thanks Matto... this bad news is good news in that I can find<br>
something else to do this weekend... unless I want to learn C, boost<br>
my IQ a notch or two and reverse-engineer my own driver!<br>
