My U3-LV runs u3allio correctly when executed using the terminal command:
However, when I issue an execution command (shell_exec("./u3allio");) from a php script running on a linux server, u3allio executes, but I get the following error message:
Open error: could not find a U3 with a local ID or a serial number of -1
If I understand the u3.c code, this really means that a call to OpenDevice returned a NULL.
I note that errno = 13 (incorrect permission).
I would appreciate comments and/or a solution. Thanks in advance. blh3620.
