Description Clark Tompsett 2001-10-29 20:24:25 UTC
From Bugzilla Helper: User-Agent: Mozilla/4.75 [en] (Win98; U) Description of problem: On a fresh installation of RH 72., upon booting, hotplug fails to load driver for Epson Photo Stylist 780 printer. Turning the printer off and back on or unplugging and replugging the usb cable allows the driver to be seen. Kernels 2.4.7-10, 2.4.9-7 and rawhide kernel 2.4.12-0.1 do not help. Installing the latest hotplug module from rawhide also does not work. This worked with RH 7.1 Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Install rh 7.2 2. boot with usb device on 3. check with usb device driver not loaded. Actual Results: usb device driver not loaded Expected Results: driver loaded Additional info:

Anything in /var/log/messages indicating the device has been run through hotplug?
Comment 2 Aleksey Nogin 2002-01-03 18:07:44 UTC
I believe this is happening because the hotplug package is missing the /etc/init.d/hotplug initialisation script. As a temporary work-around (that solved a very similar problem for me), you can add the following line: /etc/hotplug/usb.rc start to your /etc/rc.local

teg, I've just been debugging my own example where hotplug was failing to load modules at boot time. I'm not sure if it's the same problem the user here was having, but I traced my own problems down to the code elif find $MODULE_DIR -name $MODULE.o >/dev/null 2>&1 && ! $MODPROBE $MODULE >/dev/null 2>&1 ; then in /etc/hotplug/hotplug.functions. This fails for me because "find" is in /usr/bin/find, and I've got /usr mounted on a different filesystem. That's a valid config, but usb is initialised very early (to cope with usb keyboards and mice), and /usr is not yet mounted when usb first starts up so the find always fails. I've just removed the "find ... &&" clause entirely and usb startup now works perfectly. I also added a "-q" to the modprobe command to avoid too much noise if we do end up trying to load a non-existant module. btw, on a slight tangent, the hotplug.functions script has another bug which made debugging a bit harder: the conditional mesg() declaration at the top uses illegal bash syntax. # # for diagnostics # if [ -t -o ! -x /usr/bin/logger ]; is an invalid test --- "-t" takes a file descriptor argument, so I assume "-t 1" is correct here. The test fails unconditionally so debugging is forced to use syslog debugging in all cases, which is not what we want when trying to debug hotplug during boot when syslog has not started yet.

Is this still an issue with Skipjack2 or newer?
Comment 5 Trond Eivind Glomsrxd 2002-04-11 19:29:16 UTC
OK, find is no longer used and I coldplug successfully from a separate /usr myself with hotplug-2002_04_1-3.
Comment 6 Stephen Tweedie 2002-04-11 19:34:46 UTC
Works fine on a laptop here with separate /usr running 0409.1.
