#16 modprobe -v cbm -> insmod /lib/modules/4.9.0-5-amd64/misc/cbm.ko -> modprobe: ERROR: could not insert 'cbm': No such device

[Gabriel Sailer]

Hello,
after a few years doing nothing with my c64 emulator, i upgraded my hardware (xu1541 to xum1541).
My xu1541 did not work very fine with the opencbm-0.4.99.94 version i previous had installed. So i deinstall my old debian packages 'dpkg --purge libopencbm0 libopencbm0-dev opencbm opencbm-dkms opencbm-modules-source opencbm-xa1541 opencbm-xu1541' and installed the new 'opencbm-0.4.99.99' version (following the pdf install document) on my debian 9 (kernel 4.9.0-5-amd64).

The compiling and installation works fine i used the commands:

$ make -f LINUX/Makefile opencbm plugin-xum1541 plugin-xu1541 plugin-xa1541
# make -f LINUX/Makefile install install-plugin-xum1541 install-plugin-xu1541 install-plugin-xa1541

Every thing seems ok (no error occurs), but i cannot load the cbm modul ..

The cbm module is found and both devices i tried a identified correct:

The module:

# modinfo cbm

But the modprobe

Any hint what is going wrong?
Or do i miss some addidtional packages to install?

Many thanks

Are you actually using an XA1541 cable? Does your PC actually have a parallel port?

You say you followed the instructions. However, I see some important deviations from it. Or didn't you use the official instructions, but other ones?

Anyway, the instructions clearly tell you to build only the plugins that are needed. You are speaking about xu1541 and xum1541, thus, I assume you have these two, but not the xa1541 one. Thus, you also need only the corresponding plugins.

The cbm.ko kernel module handles the xa1541. For the USB based cables, it is not used at all.
It is also clearly stated at http://opencbm.trikaliotis.net/opencbm-8.html that the insmod command is only needed with the XA1541 (and XM1541) cable.

You have two options to fix your things:

1. either uninstall OpenCBM, and install it again, or
2. leave it as is, but do not try to modprobe the cbm.ko module.

Hello Spiro, sorry. It's my fault. After uninstall and 'install install-plugin-xum1541' everything works as expected.
My be my old installation leave some old parts ..
Please close the ticket.

Thank you for the fine work ;-). Now i can take a look on my old c64 floppy disks (about 100 old games and more ;-)).
