Hm,...yes after some deinstalling/reinstalling and kernel building 
now cups will find this:
	hp:/usb/Deskjet_990C?serial=ES0731D00XLG
But when I try to print the test page I get this error message:
	"/usr/local/libexec/cups/backend/hp failed"

(I am running hplip-3.9.8 backend.)

Any more ideas?

Thanks

Uli.
