I tried to upgrade hplip-0.9.8-r2 to 0.9.9 but the configure complains : "error: cannot find libusb support" It's normal, I don't have any usb port on this box (very old motherboard), so I never installed it. But I have some HP printers (supported by hplip) on parrallel port, and accessed via Windows shares. I do need the ppd's files packaged with hplip. USE="cups foomaticdb ppds -X -qt -scanner -snmp -usb"

Hello, Indeed, it looks like libusb is now a mandatory dependency. I killed the usb USE flag for hplip-0.9.9 and 0.9.10 - now libusb will always be pulled in. This is from upstream... Thanks for reporting!
