insmod error - no such device
Hi Everyone,

I am relatively new to Linux. After about three months of trying to compile a driver for a ESDCAN card, I finally found a version and kernel that worked. I am running Slackware V12.0 with kernel version 2.6.24.5-smp. When I use insmod to insert the driver file (esdcan-pci331.ko), I get an error that says -no such device.

Can anyone provide me with some guidance so I can finally get this card up and running?

Thanks,

Brian

Instead of insmod, use "modprobe", which will load any dependencies, and possibly correct and identify any IRQ settings as required. If that fails, then either (1) the card is dead (does it work for another platform??) or (2) the driver does not work (does it work with another card??) or (3) you need to manually specify options with insmod/modprobe, options which are dependent on the driver itself.

For (3), look in the source code for the possible argument strings (getstrparam() I think). You might have to, for instance, specify which IRQ and/or bus to use. To get such info, run /sbin/lspci -bv to find your device and its IRQ lines. (IRQ stand for "Interrupt Requests").
