Not All USB Zip Drives Found (BugID 4453787)

If four USB Iomega zip drives are attached, prtconf indicates that no driver is loaded after the system has booted. drvconf starts a system probe that finds only two of the four USB zip drives.

Running cat on the /dev/usb/hub0 file causes the system to add the two zip drives.

Workaround: Do not use more than two zip drives in the current release.
