I forgot to add some logs from dmesg ! usb.c: registered new driver usbscanner scanner.c: USB scanner device (0x03f0/0x0101) now attached to scanner0 scanner.c: 0.4.12:USB Scanner Driver Many: usb_control/bulk_msg: timeout And something strange: ESSCOM: III=> not our interrupt Buffer over turn (many) usb-uhci.c: interrupt, status 3, frame# 61 scanner.c: read_scanner(0): funky result:-84. Consult Documentation/usb/scanner.txt. usb.c: USB disconnect on device 00:11.2-2 address 2 hub.c: new USB device 00:11.2-2, assigned address 3 scanner.c: USB scanner device (0x03f0/0x0101) now attached to scanner0 hub.c: new USB device 00:11.3-1, assigned address 2 I will do another run without the ESSCOM module loaded (ESS 2839 driver) to be sure... And try the hp_scan.c test from Documentation/usb/scanner.txt -- Yves Martin
