Linuxhelp _ Programming in Linux _ Read Caching

Posted by: beber Aug 14 2006, 04:22 AM

I'm trying to read from a USB device & need to cancel data caching completely.
I tried using the O_DIRECT flag when opening the device, but then the read operation fails.
Any ideas how I may do that?

I'm working on Fedora Core 4 (kernel 2.6.11).
