BTW, is there a database or repository to check on existing drivers before buying a device? My understanding that in most cases Linux drivers aren't provided by manufacturers but mostly by a community. I found numerous discussion forums for Ubuntu and some HCLs.
And, is there an issue of using old drivers with newer versions of kernel, or they are compatible? It's my understanding that 64-bit and 32-bit require different drivers.
Are Linux drivers universal and fit into all Linux flavors or let say Fedora needs one driver and Debian another?

Hi all!
I am trying to register a device in an existing device class, but I am
having trouble getting the pointer to an existing class.
I can create a class in a module, get the pointer to it and then use
it to register the device with:

sbp_targ
SBP_TARG(4) BSD Kernel Interfaces Manual SBP_TARG(4)
NAME
sbp_targ -- Serial Bus Protocol 2 (SBP-2) Target Mode devices driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file:
device sbp_targ
device firewire
device scbus
device targ
Alternatively, to load the driver as a module at boot time, place the following lines in loader.conf(5):
firewire_load="YES"
cam_load="YES"
sbp_targ_load"YES"
DESCRIPTION
The sbp_targ driver provides support for SBP-2 target mode. This driver is supposed to work with cam(4), targ(4) and firewire(4). You also
need to use scsi_target(8), which can be found in /usr/share/examples/scsi_target, to provide actual devices.
EXAMPLES
# mdconfig -a -t malloc -s 10m
md0
# scsi_target 0:0:0 /dev/md0
(Assuming sbp_targ0 on scbus0)
SEE ALSO
cam(4), firewire(4), targ(4), camcontrol(8), fwcontrol(8), kldload(8), scsi_target(8)
AUTHORS
The sbp_targ driver was written by Hidetoshi Shimokawa.
BUGS
This driver is currently under development. It does not work correctly in multi-initiator environments or after the bus topology has been
changed.
