I recently upgraded my IBM X20 notebook to Red Hat Linux 7.2
and would like to use a couple of serial
<br>devices that work fine when the computer is booted into WIN2K.
<p>1) When a Targus PAUM003 USB mouse is plugged in, the following
is printed /var/log/messages:
<br>
<blockquote>Dec 12 13:38:25 mike-laptop kernel: hub.c: USB new device connect
on bus1/1, assigned device number 2
<br>Dec 12 13:38:25 mike-laptop kernel: hub.c: USB hub found
<br>Dec 12 13:38:25 mike-laptop kernel: hub.c: 2 ports detected
<br>Dec 12 13:38:25 mike-laptop /etc/hotplug/usb.agent: ... no drivers
for USB product 451/2036/101
<br>Dec 12 13:38:26 mike-laptop kernel: hub.c: USB new device connect on
bus1/1/2, assigned device number 3
<br>Dec 12 13:38:26 mike-laptop kernel: input0: USB HID v1.00 Mouse [KYE
Genius USB Wheel Mouse] on usb1:3.0
<br>Dec 12 13:38:26 mike-laptop /etc/hotplug/usb.agent: ... can't load
module mousedev</blockquote>
What needs to do next in order to use this mouse from Linux?
<p>2) When a USC-2000 USB serial converter is plugged in, the following
is printed in /var/log/messages:
<blockquote>Dec 12 13:42:35 mike-laptop kernel: hub.c: USB new device connect

<br> </blockquote>
What needs to do next in order to use this USB to serial converter?
<p>Thanks for your help,

Sorry I can't quote your email, but it was sent in html format, which is
not a nice thing to send to mailing lists.
Anyway, it sounds like these are general Linux USB questions, and the
Linux USB Guide and FAQ should answer them:

thanks,

Did you verify that you can't use it? If "mousedev" is statically
linked into your kernel, you should be able to use it already.
I often get that message when I connect a USB mouse; it's
still usable
So far as I know, there's no standard way for the hotplug
scripts to tell when the reason a module can't be loaded
is that it's been statically linked. "lsmod" only shows the
dynamically linked modules, not the statically linked ones,
and "modprobe" fails when it can't be dynamically linked,
even if the module is already statically linked.

For the USB case, parse /proc/bus/usb/drivers?
Maybe we can come up with equivalent for other hotplug systems during 2.5? The
work on conversion to driverfs and other gucci vfs things could probably be
expanded to other subsystems.

That one wasn't a "usb" driver, it's an "input subsystem" driver.
An early USB-only version of the hotplug scripts did look at the
/proc/bus/usb/drivers file, and knew how to work around the
fact that some driver and module names don't match. (One
that comes to mind is "keyboard" vs "usbkbd".) The current
version doesn't ... maybe because after converting to use
the "modules.usbmap" file, it wasn't usually an issue. (The
"mousedev" module in question uses "usb.handmap" to
work around the "no input hotplug" issue.)

I'd rather see a generic solution that's not specific to
drivers, myself. It's not the sort of thing every driver
subsystem should need to re-invent, IMO.
