Looks like you have the Mac version of the QuickCam, which is indeed a<br>
|
|
serial device, of sorts. The qcam driver is for the PC version which<br>
|
|
is a parallel port device, and the driver directly flips bits on the<br>
|
|
parallel port, which is why it needs the port address. So, I'd say<br>
|
|
you're kind of out of luck from that perspective.<br>
|
|
<p>
|
|
feature of the Mac serial port, whereby the Mac could clock data<br>
|
|
in/out of the port at some high rate, like 1Mbps or so, which is<br>
|
|
why the Mac version couldn't be used on a PC (and hence no x86-linux<br>
|
|
driver for the Mac version, that I ever heard of).<br>
