Re: [njbfs-bugs] Support for 2.4.18-26.8.0 kernels?

[Danish Q. <dx...@nj...>]

Hi Neil,

I have been able to patch my njbfs module against this problem, and load
the module into a 2.4.20 kernel. The core reason is rooted with the minor
device numbers when the device is registered with the USB subsystem.

Here's a quick unified diff patch that should get you up and working while
we investigate the problem.
