HP Scanjet 6200C USB vs FC2

[Martin Ewing]

Folks, a tale of woe...

My HP ScanJet 6200C was working fine with FC1, using USB. Under FC2, 
it's really weird. sane-find-scanner gives "found USB scanner 
(vendor=0x03f0, product=0x0201) at libusb:002:002" . So far, so good.  
But note that sane-find-scanner does NOT report the product/manufacturer 
ASCII info.

Now scanimage -L (run as root) gives one of 3 responses:
1. Segmentation fault
2. device `hp:libusb:002:002' is a Hewlett-Packard ScanJet 62x0C flatbed 
scanner (good!), or
3. No scanners were identified....

I get all 3 responses randomly as I retry 'scanimage -L'. I have tried 
reorganizing my USB ports, power cycling, etc. - same kind of thing.

/var/log/messages (after my su to root):
May 21 10:43:57 localhost kernel: ppdev: user-space parallel port driver

(here I power cycled my scanner)

All this is on an ASUS A7V8X-MX, Athlon 2000+, 1 GB RAM, etc., etc.

p.s. Here is my 'lsmod'

-----------
There was a hint that the latest sane/xsane packages might have fixed 
some HP problems, so I compiled them and replaced the FC2 RPMs.  No 
luck, same behavior.  Other people report that the current sane works OK 
with this scanner and USB -- so it's either a hardware problem or a 
Fedora/USB problem, I guess.

I have dropped back and connected the Scanjet via its SCSI port.  Works 
fine that way.
