This is the output I get from Mandrake 9.0 which can get my scanner working. cat /proc/bus/usb/drivers T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 4 B: Alloc= 0/900 us ( 0%), #Int= 0, #Iso= 0 D: Ver= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=0000 ProdID=0000 Rev= 0.00 S: Product=USB OHCI Root Hub S: SerialNumber=e4933000 C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr= 0mA I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub E: Ad=81(I) Atr=03(Int.)

As I understand it, support for this device comes from the HP Office Jet project (hpoj). Does that sound right?
That's interesting - your USB scanner does not appear in the SCSI device listing. I had thought that all USB scanners interface with sane via the piggy-back SCSI driver.
hpoj seems right. If you go to www.hp.com search for linux scanner/printer support you get to a sourceforge page which gives all the details you need. I have tested the scanner under Mandrake 9.0 and it works perfectly via sane.
Okay, changing to an RFE for hpoj. A preliminary package for that can be found in rawhide.
