Hi , all I'm writing a program to control one scanner via usb under linux.I use libusb to interact with usb .I write the program with following step: 1. usb_init 2. usb_find_busses 3. usb_get_busses and make a loop to find the scanner 4. usb_open to open scanner 5. usb_set_configuration to config the scanner 6. usb_claim_interface to claim interface 7. usb_bulk_write - write some command to scanner Now the program stoped in step6 and I got the following tips in KDevelop:Program terminated with signal SIGSEGV,Segme. What does that mean?Is there something I did wrong??Thanks for any help! |
