Tim, thanks for the reply.
I've removed the call to usb_set_configuration. The Error message went away. Now I am facing another problem. A call to usb_claim_interface returns 0 (meaning call was OK). The next call, after the usb_claim_interface, is a call to usb_control_msg. It returns -110 (aka it fails). What should I do to debug this ? Or, even better, what should I do to make this call pass ? Igor P.S: Reminder: I am running this on a CentOS 6.5 as the __guest__ using VirtualBOX on WIN7 as the host. Running the program on CentOS 6.5 on REAL hardware works flawlessly. ------------------------------------------------------------------------------ HPCC Systems Open Source Big Data Platform from LexisNexis Risk Solutions Find What Matters Most in Your Big Data with HPCC Systems Open Source.
