I regularly use the 9 pin serial ports on my pc for bringing in external data. Can anyone confirm that USB ports are already opto-isolated?

Not certain; but you can get optoisolated USB hubs.

I use both win2k and linux fedora but didn't thnik the os made any difference?

thanks diodorus. I know I can get isolated hubs but thought i'd heard that ports themselves were isolated. could be wrong i suppose - why else make isolated hubs?

No, the OS doesn't make a difference here.

Only google might be able to give an answer one way or another I suppose...

Thanks Dio. I'll keep looking around.
