I was redoing the kernel cause found IOMMU support disabled my agp when booted up. SO, tried the above idea and works! Scanner was recognized and XSane found scanner. Was able to actually scan a document. Did it on both 2.6.14 & 2.6.13 kernel. The only thing could tell that was different was that the one did on 2.6.14 was lighter and looked better. Don't know why, maybe if rescanned again on both it would show it was somewhat random and due to Sane. Anyway. When recompile the kernel on 2.6.14 did get these errors (but didn't stop it from working): drivers/usb/image/microtek.c: In function `mts_debug_dump': drivers/usb/image/microtek.c:217: warning: cast from pointer to integer of different size drivers/usb/image/microtek.c: In function `mts_int_submit_urb': drivers/usb/image/microtek.c:376: warning: cast from pointer to integer of different size drivers/usb/image/microtek.c:376: warning: cast from pointer to integer of different size drivers/usb/image/microtek.c: In function `mts_transfer_cleanup': drivers/usb/image/microtek.c:402: warning: cast from pointer to integer of different size drivers/usb/image/microtek.c:402: warning: cast from pointer to integer of different size drivers/usb/image/microtek.c: In function `mts_transfer_done': drivers/usb/image/microtek.c:411: warning: cast from pointer to integer of different size drivers/usb/image/microtek.c:411: warning: cast from pointer to integer of different size drivers/usb/image/microtek.c: In function `mts_get_status': drivers/usb/image/microtek.c:425: warning: cast from pointer to integer of different size drivers/usb/image/microtek.c:425: warning: cast from pointer to integer of different size drivers/usb/image/microtek.c: In function `mts_data_done': drivers/usb/image/microtek.c:438: warning: cast from pointer to integer of different size drivers/usb/image/microtek.c:438: warning: cast from pointer to integer of different size drivers/usb/image/microtek.c: In function `mts_command_done': drivers/usb/image/microtek.c:455: warning: cast from pointer to integer of different size drivers/usb/image/microtek.c:455: warning: cast from pointer to integer of different size drivers/usb/image/microtek.c: In function `mts_do_sg': drivers/usb/image/microtek.c:496: warning: cast from pointer to integer of different size drivers/usb/image/microtek.c:496: warning: cast from pointer to integer of different size drivers/usb/image/microtek.c: In function `mts_usb_probe': drivers/usb/image/microtek.c:715: warning: cast from pointer to integer of different size Just thought would let you know.
