After detaching the mounted usb-flash device, no new usb-devices are detected.
USB controller is "device = 'SB700 USB OHCI1 Controller"
How-To-Repeat: 1) attach (vfat-formated, did not test with other fs) flash device, mount it
2) detach without umounting
3) try to attach another usb-device
4) see no new devices, no dmesg messages, nothing

debug support) i could not reproduce that bug. Before kernel-update it
has happened not every time, so i wanted to see what happens for a
couple of days.
