Please help, does RHEL support user space drivers?
Please forgive me for being impatient. I have a 3:30EDT (19:30UTC) meeting today where it's important to know the answer. I haven't been able to find the answer through my searches.
Does the latest version of RHEL support user space drivers? I may need a user space character driver. My research suggests that in other versions of linux, this is associated with a set of patches nicknamed CUSE. [EDIT: Or maybe it's an lkm FUSE with CUSE extension. Doc is hard to come by.]
More details about my usage appear at:

Thanks VERY much,

Had never heard of this, but:
CUSE was added to FUSE in 2008, so it will be in all later kernels: https://lwn.net/Articles/308445/
We have a
cuse.cin the kernel: https://access.redhat.com/labs/psb/versions/kernel-3.10.0-862.el7/fs/fuse/cuse.cWe have the compile option turned on as a loadable module:
# grep CUSE /boot/config-3.10.0-862.el7.x86_64
CONFIG_CUSE=m
I've loaded third-party FUSE modules before (sshfs) and that worked fine.
So if you have a userspace character driver which follows the CUSE API, it should work too.
