Finally I found some time to setup a FreeBSD VM and check the libusb0 issue. It is now fixed. The problem was that I was using pathconf function to set my _PATH_MAX variable. pathconf returned 255, but the PATH_MAX in the limits header file is 1024. Now it should work. I believe the Max OSX issue is the same, and also other BSDs should suffer from the same problem. Could someone with access to Mac OSX check what's the value of PATH_MAX macro? We need to know that value for NetBSD and OpenBSD (does libusb 0 run under NetBSD and OpenBSD?). -- Best Regards, Wander Lairson Costa ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
