scanner not recognized any more

[David Jansen]

Since rebooting my FC4 system with the latest kernel (2.6.16-1.2096_FC4smp)
my scanner, a HP scanjet 5300C connected through usb, is not recognized
any more. When plugging it in I get:

usb 3-1: new full speed USB device using uhci_hcd and address 2
usb 3-1: configuration #1 chosen from 1 choice
usb 3-1: can't set config #1, error -71

and of course, this results in no device that sane can use. Rebooting
back in kernel kernel-2.6.15-1.1833 makes the device work again.

However, sane-find-scanner reports:
  found USB scanner (vendor=0x03f0, product=0x0701) at libusb:003:002
so the device is not completely missing. Only question is: what do I do
to make sane see it, or, what changed in the last couple of kernel
updates?
