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:
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!
