I use kernel 2.4.21 with scanner module that came with that kernel. I have an Epson CX5200 printer/scanner/copier device. As of right now I load all my needed usb modules on system boot. What often happens is the scanner doesn't respond when xsane tries to scan. I have to wait for xsane to time-out and unload/reload scanner.o. Sometimes this fixes the problem. When it doesn't work, reloading usb-uhci does help half of the time. I suspect it might be a bigger usb problem than just limited to scanner.o. I haven't tried using libusb, but since the problem doesn't seem limited to scanner.o, I don't think it will help. The only diagnostic message given by the kernel is: kernel: usb_control/bulk_msg: timeout Please tell me what else I can try, or what other information to provide. And out of curiosity, is there a reason why usb devices don't work with alias char-major-..... in /etc/modules.conf?
