[Mono-list] System.DllNotFoundException, but dll is there.

Wed Oct 21 00:54:55 EDT 2009

Well.. The libsub was reinstalled and the msg bellow has gone. 

> Mono-INFO: DllImport error loading library './libUFScanner.so: undefined
> symbol: usb_bulk_read'. 

The App loads normal until the btn that initializes the scanner is clicked,
then the mess has start! :_) 

Chris got the point, the UFScanner.dll is used to manager the Scanner and it
does not work. 

I have a file named libUFScanner.so that I think be a Linux compiled version
of UFScanner.dll. But I don't know how to use it. May you give me a light ??
