I have an HP SCANJET 4500c scanner. It works well under Windows but I want get rid off such operating system. I found my scanner is supported by SANE development source using HP5590 backend. When I issue the command sane-find-scanner it returns:
This is sane-find-scanner from sane-backends 1.0.21cvs # sane-find-scanner will now attempt to detect your scanner. If the # result is different from what you expected, first make sure your # scanner is powered up and properly connected to your computer. trying libusb: <device descriptor of 0x03f0/0x1205 at 001:014 (Hewlett-Packard hp scanjet scanner)> bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 255 bDeviceSubClass 255 bDeviceProtocol 255 bMaxPacketSize0 64 idVendor 0x03F0 idProduct 0x1205 bcdDevice 2.00 iManufacturer 1 (Hewlett-Packard) iProduct 2 (hp scanjet scanner) iSerialNumber 12 (CN25SS10YB) bNumConfigurations 1 <configuration 0> bLength 9 bDescriptorType 2 wTotalLength 39 bNumInterfaces 1 bConfigurationValue 1 iConfiguration 0 () bmAttributes 192 (Self-powered) MaxPower 10 mA <interface 0> <altsetting 0> bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 3 bInterfaceClass 16 bInterfaceSubClass 1 bInterfaceProtocol 0 iInterface 0 () <endpoint 0> bLength 7 bDescriptorType 5 bEndpointAddress 0x81 (in 0x01) bmAttributes 2 (bulk) wMaxPacketSize 512 bInterval 0 ms bRefresh 0 bSynchAddress 0 <endpoint 1> bLength 7 bDescriptorType 5 bEndpointAddress 0x02 (out 0x02) bmAttributes 2 (bulk) wMaxPacketSize 512 bInterval 0 ms bRefresh 0 bSynchAddress 0 <endpoint 2> bLength 7 bDescriptorType 5 bEndpointAddress 0x83 (in 0x03) bmAttributes 3 (interrupt) wMaxPacketSize 1 bInterval 8 ms bRefresh 0 bSynchAddress 0 <trying to find out which USB chip is used> checking for GT-6801 ... this is not a GT-6801 (bcdUSB = 0x200) checking for GT-6816 ... this is not a GT-6816 (bDeviceClass = 255, bInterfaceClass = 16) checking for GT-8911 ... this is not a GT-8911 (check 1, bDeviceClass = 255, bInterfaceClass = 16) checking for MA-1017 ... this is not a MA-1017 (bDeviceClass = 255, bInterfaceClass = 16) checking for MA-1015 ... this is not a MA-1015 (bcdUSB = 0x200) checking for MA-1509 ... this is not a MA-1509 (bcdUSB = 0x200) checking for LM983[1,2,3] ... this is not a LM983x (bDeviceClass = 255, bInterfaceClass = 16) checking for GL646 ... this is not a GL646 (bDeviceClass = 255, bInterfaceClass = 16) checking for GL646_HP ... this is not a GL646_HP (bDeviceClass = 255, bInterfaceClass = 16) checking for GL660+GL646 ... this is not a GL660+GL646 (bDeviceClass = 255, bInterfaceClass = 16) checking for GL84x ... this is not a GL84x (bDeviceClass = 255, bInterfaceClass = 16) checking for ICM532B ... this is not a ICM532B (check 1, bDeviceClass = 255, bInterfaceClass = 16) checking for PV8630/LM9830 ... this is not a PV8630/LM9830 (bDeviceClass = 255) checking for M011 ... this is not a M011 (bcdUSB = 0x200) checking for RTS8822 ... this is not a RTS8822 (bDeviceClass = 255) checking for rts8858c ... this is not a rts8858c (bDeviceClass = 255) checking for SQ113 ... this is not a SQ113 (bDeviceClass = 255) checking for HP4500C/4570C/5500C/5550C/5590/7650 chipset ...
