Hello there, I want to get a data from my usb device using libusb. I think I should use usb_control_msg to get data from usb device, Should I use:
1. usb_control_msg(my_dev, 0xC1, 0x00, 0x0000, 0x0521, buffer, 0x0001, 5000) or 2. usb_control_msg(my_dev, 0xC1, 0x00, 0x0000, 0x0521, NULL, 0x0001, 5000) ? I guess I should use 1, since data from usb will be stored in buffer, am I right? Thanks. Regards, Joe. ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!
