I have a kernel module that loads manually fine, but refuses to load on demand. What sort of things should I be looking for to fix this?
The module is for my Plustek scanner. I posted the below to the Plustek list a few days ago but didn't get any leads. Perhaps someone here will have an idea or two? ---original message begins--- After following the howto at http://www.gjaeger.de/scanner/howtos/NewbiePlustekHowto/NewbiePlustekHowto.html my scanner works if and only if I load the pt_drv module by hand. Upon boot, lsmod assures me that parport and parport_pc are loaded: parport_pc 14384 1 parport 13920 1 [lp parport_pc] If I now run scanimage -L I am told "No scanners were identified", and returning to lsmod shows me that running scanimage did not cause pt_drv to load. If I now cd to the /plustek_driver directory and make load, everything works (scanimage -L returns "device `plustek:/dev/pt_drv' is a Plustek 9636T/12000T flatbed scanner", lsmod returns in part "pt_drv 112544 0", and the scanner works)... until the next reboot. Then I have to load the module by hand again. I'm using Mandrake 8.1, kernel 2.4.8-26mdk (I've turned off IEEE 1284), and a Genius Color Page-Vivid Pro II Film scanner, which is a relabeled Plustek 9636T. During normal use I will want to plug my laser printer into the back of the scanner, but for now it is disconnected to avoid any conflicts. (I have tested this, however, and scanner and printer work fine together once the module is loaded.) /etc/modules.conf reads in part: alias char-major-40 pt_drv pre-install pt_drv modprobe -k parport options pt_drv lampoff=180 warmup=15 port=0x378 forceMode=0 mov=0 The only odd thing about my setup is the BIOS parallel port settings. The only options available are enabled, disabled, auto, and floppy. This doesn't make sense to me, and there is no mention of EPP or anything else normal. I've tried all settings with the same result. /proc/sys/dev/parport/parport0/modes tells me in every case "PCSPP", which I take to be standard (not EPP) mode. Any ideas, anyone? I'd really like to avoid having to make install every time I want to use the scanner. TIA, Warren
