RE: What am I doing wrong? IBMCAM not found

Looks like Dmitri saved me, the software didn't get the information from the
driver, but everything else was working fine.  I did the manual route for
the snapshots and all works great.  

Thank you all.  I should have tested with other tools first.  

I am running Stock RH 7.2 and just the basics.
	P233 MMX 
	ATI Mach64 Based 2Mb Video Card
	ASUS Motherboard of some type.


The good news, It works.  I am happy about that.  But the USB driver is Slow
to respond.  I'll have to look into why, and how to increase the size.

Just out of curiosity... Are you running RedHat 7.2?  If so what are
your hardware specs for your motherboard, processor, video card...?
