Hi all, I'm new in this list and i'm approaching libusb programming. Trying to write a sane backend for my scanner, i do the following steps:
open the device with scanner = usb_open(dev); set the device configuration with usb_set_configuration(scanner, 1); claim the device with usb_claim_interface(scanner, 0); when i try to send any data to the device: usb_bulk_write(scanner, 81, cmd, length, 1000) returns -22 (Invalid argument). I'm wondering what is the "Invalid argument" referred to? ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
