A couple of people have reported to me that they see the following syslog messages:
Mar 22 21:51:41 titan kernel: usb_control/bulk_msg: timeout Mar 22 21:51:41 titan kernel: scanner.c: ioctl_scanner(0): control_msg returned -110 This for the canon630u backend -- but I'm wondering if anyone else with a USB backend that uses USB control messages has seen something similar. The scanners are connected and viewable through /proc/bus/usb and the usbscanner driver has asssociated with them. Changing the timeout value in scanner.c doesn't make a difference. Since I don't have this problem myself, it's been hard for me to do anything to investigate further. The two cases reported so far have been with scanner firmware rev 0.01 (/proc/bus/usb/devices P: Vendor=04a9 ProdID=2204 Rev= 0.01) My (working) scanner is rev 0.05 -- anyone else for whom it's working or not, please let me know your rev. -- [email protected]
