Hey! I've a question regarding the epsonds backend. I'm trying to get my scanner working with the latest 1.0.25 release of sane-backends. I got it to a point where it now finds the scanner once when using
scanimage -L but after that it doesn't find the scanner ever again until I unplug and plug it back again (USB). Here is the debugging output of the scanimage -L command I've used (https://gist.github.com/walski/7117f69c9e70b1733c6b14c928050ada <https://gist.github.com/walski/7117f69c9e70b1733c6b14c928050ada>): *# First Run:* sudo SANE_DEBUG_EPSONDS=128 scanimage -L > [sanei_debug] Setting debug level of epsonds to 128. > [epsonds] sane_epsonds_init: sane-backends 1.0.25 > [epsonds] epsonds backend, version 1.0.35 > [epsonds] ** sane_epsonds_get_devices > [epsonds] probe_devices > [epsonds] attach_one_config: len = 15, line = usb 0x4b8 0x150 > [epsonds] user configured device > [epsonds] attach_one_usb: dev = libusb:001:006 > [epsonds] attach: devname = libusb:001:006, type = 1 > [epsonds] device_detect > [epsonds] open_scanner: libusb:001:006 > [epsonds] opened correctly > [epsonds] eds_lock > [epsonds] eds_control: size = 2 > [epsonds] eds_send: size = 2 > [epsonds] eds_send: FS X > [epsonds] eds_recv: size = 1, buf = 0x7eacc1ff > [epsonds] = gathering device information > [epsonds] esci2_cmd: INFOx0000000 len 12, payload len: 0 > [epsonds] eds_send: size = 12 > [epsonds] eds_recv: size = 64, buf = 0x7eacc1b0 > [epsonds] info_cb: nrd / NONE / 4 > [epsonds] eds_recv: size = 256, buf = 0x1e69ce8 > [epsonds] info_cb: ADF / TYPEFEED / 8 > [epsonds] ADF: sheet feed type > [epsonds] info_cb: ADF / DPLX1SCN / 8 > [epsonds] ADF: duplex single pass > [epsonds] info_cb: ADF / FORDPF1N / 8 > [epsonds] ADF: order is 1 to N > [epsonds] info_cb: ADF / ALGNCNTR / 8 > [epsonds] ADF: center aligned > [epsonds] info_cb: ADF / AREAi0000850i0001400 / 20 > [epsonds] ADF: area 850x1400 @ 100dpi > [epsonds] info_cb: ADF / AMINi0000200i0000205 / 20 > [epsonds] ADF: min 200x205 @ 100dpi > [epsonds] info_cb: ADF / AMAXi0000850i0003600 / 20 > [epsonds] ADF: max 850x3600 @ 100dpi > [epsonds] eds_set_adf_area: 0.000000,0.000000 215.899994,914.399994 100 > [mm] > [epsonds] info_cb: ADF / RESOi0000600 / 12 > [epsonds] ADF: basic resolution is 600 dpi > [epsonds] info_cb: ADF / RCVR / 4 > [epsonds] ADF: auto recovery > [epsonds] info_cb: ADF / OVSNd000d039 / 12 > [epsonds] ADF: overscan 0x39 @ 100dpi > [epsonds] info_cb: IMX / x000FFFFx000FFFF / 16 > [epsonds] info_cb: PRD / h008DS-560 / 12 > [epsonds] product: DS-560 > [epsonds] info_cb: VER / h010IPL 1.00ADF 1.05 / 20 > [epsonds] version: IPL 1.00ADF 1.05 > [epsonds] info_cb: DSZ / i0001536 / 8 > [epsonds] info_cb: DLS / / 0 > [epsonds] info_cb: S/N / h00AU6NZ019428 / 14 > [epsonds] serial: U6NZ019428 > [epsonds] esci2_cmd: CAPAx0000000 len 12, payload len: 0 > [epsonds] eds_send: size = 12 > [epsonds] eds_recv: size = 64, buf = 0x7eacc1c0 > [epsonds] capa_cb: nrd / NONE / 4 > [epsonds] eds_recv: size = 228, buf = 0x1e69ce8 > [epsonds] capa_cb: ADF / DPLX / 4 > [epsonds] ADF: duplex > [epsonds] capa_cb: ADF / DFL1DFL2 / 8 > [epsonds] ADF: double feed detection (high sensitivity) > [epsonds] capa_cb: ADF / EJCT / 4 > [epsonds] ADF: paper eject > [epsonds] capa_cb: ADF / OVSN / 4 > [epsonds] ADF: overscan > [epsonds] capa_cb: COL / LISTC024M001M008R001R008G001G008B001B008 / 40 > [epsonds] capa_cb: FMT / LISTJPG / 8 > [epsonds] capa_cb: JPG / RANGd001d100 / 12 > [epsonds] capa_cb: THR / RANGd000d255 / 12 > [epsonds] capa_cb: GMM / LISTUG10UG18 / 12 > [epsonds] capa_cb: GMT / LISTRED GRN BLU MONO / 20 > [epsonds] capa_cb: CMX / LISTUNITUM08 / 12 > [epsonds] capa_cb: RSM / LISTi0000300i0000600 / 20 > [epsonds] eds_add_resolution: add (dpi): 300 > [epsonds] eds_add_resolution: add (dpi): 600 > [epsonds] capa_cb: RSS / LISTi0000300i000060 / 19 > [epsonds] esci2_cmd: RESAx0000000 len 12, payload len: 0 > [epsonds] eds_send: size = 12 > [epsonds] eds_recv: size = 64, buf = 0x7eacc1c0 > [epsonds] resa_cb: nrd / NONE / 4 > [epsonds] resa_cb: par / OK / 4 > [epsonds] eds_recv: size = 1184, buf = 0x1e69ce8 > [epsonds] resa_cb: ADF / / 0 > [epsonds] resa_cb: COL / M001 / 4 > [epsonds] resa_cb: FMT / JPG / 4 > [epsonds] resa_cb: JPG / d090 / 4 > [epsonds] resa_cb: THR / d128 / 4 > [epsonds] resa_cb: GMM / UG10 / 4 > [epsonds] resa_cb: $%& / > '()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????BLU > h100 / 225 > [epsonds] resa_cb: $%& / > '()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????MONOh100 > / 225 > [epsonds] resa_cb: $%& / > '()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????
