If you're running a sufficiently new version of Linux, I believe /etc/modprobe.conf will do what you want. Use the install primitive to give a command line type argument for what you want. In your case, probably modprobe the prerequisite module followed by modprobing usbhid. When you modprobe usbhid you probably want to use the --ignore-install switch so you don't get into an infinite loop. I've even seen a sleep command put between the two modprobes. Separate the commands with semicolons like you would do in bash.

I am no expert on this (which is why I didn't put something specific between code tags), but I think this is the general direction you want to go.

but usbhid is allready getting loaded somewhere... (?) and it's not in /etc/modules

i'm running debian so there's no /etc/modprobe.conf - only /etc/modules and /etc/modprobe.d (dir)

A thousand pardons! I was not at a Linux machine when I typed that. On Ubuntu (which is based on Debian) there is indeed not a /etc/modprobe.conf. (Although perhaps one could be created and it would work???) But the files in /etc/modprobe.d are treated as if they were part of modprobe.conf.

As an example, when I needed to alter the behavior when the em28xx module was loaded, following directions I found on the Internet, I created the file /etc/modprobe/dvbstick:

Code:
$ cat /etc/modprobe.d/dvbstick 
install em28xx /sbin/modprobe --ignore-install em28xx; /bin/sleep 2; /sbin/modprobe em2880-dvb
Now this installs an additional module after the specified module rather than before, as you want, but the basic method is the same.

In your case, I don't know what is loading usbhid, but as I understand it, if whatever it is is using modprobe to do so, the behavior can be altered with a file in /etc/modeprobe.d.
