[Libusb-devel] Help! usb_find_busses() error in ARM linux

[Daly Y. <dal...@ya...>]

Hello,
    
    I am developing an application to drive an usb
device on an embedded linux ARM board (AT91RM9200,
Linux 2.4.27-vrs1). I downloaded the libusb-0.1.12,
cross-compiled it in redhat-linux 9.0 (Linux 2.4.20-8)
with arm-linux-gcc 3.4.1, then download to the ARM
board, but the function call usb_find_busses() return
-2, what is the meaning of the error code -2? Please
help, thank you very much.
 
Best regards, 
Daly
