A way to stop/restart USB support without rebooting?

Is there a way for me to stop and start USB support without rebooting?

I have a multi card reader that I've managed to get working perfectly ... as well as the system doesn't get rebooted. Sometimes, after a reboot, when I try to mount the flash card in one of the slots, the system hangs, my caps and num lock leds start flashing and I have NO ability to input anything.

usb mass-storage is loaded at boot, as is multi LUN support

The only way I've been able to solve this is by unplugging the USB cable, booting without it, and then plugging it back in and letting the system detect it.

So I'm thinking ... is there a way to shutdown and restart the USB support without having to reboot? I want to see if that solves the problem.

Oh, R.H. 9.0 with Gnome.

you probably have kernel 2.4.xx?

just shut down the usbd. do it nicely with the3 start stop scripts you have in /etc/init.d somewhere, or just send a SIGHUP (or even SIGTERM) to the usbd process. if you send sigterm, you must restart the daemon again...

Thanks for your quick reply.
I'll give that a shot the next time the error happens.

Thanks again for your time.

(It says member now ... but I sure feel like a newbie still!)
