I've run into this problem a few times. When I plug in a USB mass storage device, such as my Kindle or my iPhone 4, it will show up as a device and I can mount it, and everything is great. However, if I unmount it and unplug it, and then plug it in again, it isn't detected by the USB system. I have tried different cables to no avail. I've tried to modprobe -r modules like usb_common and usb_core but am not able to because they're in use. I imagine I would need to track down all of the USB activity on my system and remove all of the various modules being used in sequence, and then re-add them again. Is there an easier way to reset my USB drivers without rebooting my machine? -Erik -- Erik K. Mitchell erik.mitchell at gmail.com
