6 sane-mustek_usb - SANE backend for Mustek USB flatbed scanners
7
9 The sane-mustek_usb library implements a SANE (Scanner Access Now Easy)
10 backend that provides access to Mustek USB flatbed scanners (including
11 a clone from Trust). At present, the following scanners are known to
12 work more or less with this backend:
13 Mustek 600 CU
15 Mustek 1200 UB
16 Mustek 1200 CU
17 Mustek 1200 CU Plus
18 Trust Compact Scan USB 19200
19 More details can be found on the Mustek USB backend homepage
21 http://www.meier-geinitz.de/sane/mustek_usb-backend/.
22 The Mustek BearPaw 1200 and 2400 scanners are supported by the plustek
24 backend. See sane-plustek(5) for details. The Mustek BearPaw 1200F is
25 supported by the MA-1509 backend. See sane-ma1509(5) for details. Other
26 Mustek USB scanners are supported by the gt68xx backend, see
27 sane-gt68xx(5).
28 This backend can only work with scanners that are already detected by
30 the operating system. See sane-usb(5) for details.
31 If you own a Mustek (or Trust) scanner other than the ones listed above
33 that works with this backend, please let me know this by sending the
34 scanner's exact model name and the USB vendor and device ids (e.g. from
35 /proc/bus/usb/devices or syslog) to me.
36
39 This backend expects device names of the form:
40 special
42 Where special is a path-name for the special device that corresponds to
44 a USB scanner. With Linux, such a device name could be /dev/usb/scan‐
45 ner0 or /dev/usbscanner1, for example.
46 For FreeBSD use /dev/uscanner0.
48
51 The contents of the mustek_usb.conf file is a list of options and
52 device names that correspond to Mustek USB scanners. Empty lines and
53 lines starting with a hash mark (#) are ignored. If a device name is
54 placed in mustek_usb.conf, it must be followed by a line containing the
55 keyword option and an option specifying the scanner type. The following
56 options can be used: 600cu, 1200cu, 1200cu_plus, 1200ub. For the Trust
57 Compact Scan USB 19200 use `option 1200ub'.
58 Instead of using the device name, the scanner can be autodetected by
60 usb vendor_id product_id statements which are already included into
61 mustek_usb.conf. This is only supported with Linux 2.4.8 and higher
62 and all systems that support libsub. "vendor_id" and "product_id" are
63 hexadecimal numbers that identify the scanner. If this doesn't work, a
64 device name and the option specifying the scanner type must be placed
65 in mustek_usb.conf as described above.
66 The global option max_block_size can be used to limit the amount of
68 data acquired in one turn from the USB system. It may be worth trying,
69 if USB errors occur.
70 A sample configuration file is shown below:
72 # Comment
74 option max_block_size 1024
75 usb 0x055f 0x0001
76 /dev/usb/scanner0
77 option 600cu
78 The first line is ignored. The second line sets the buffer size to a
80 maximum of 1024 bytes. The third line tries to autodetect a scanner
81 with vendor id 0x055f and product id 0x0001 (Mustek 1200 CU). The
82 fourth line tells the backend to attach to /dev/usb/scanner0 and the
83 fifth line specifies that /dev/usb/scanner0 is a Mustek 600 CU.
84
86 /etc/sane.d/mustek_usb.conf
87 The backend configuration file (see also description of
88 SANE_CONFIG_DIR below).
89 /usr/lib64/sane/libsane-mustek_usb.a
91 The static library implementing this backend.
92 /usr/lib64/sane/libsane-mustek_usb.so
94 The shared library implementing this backend (present on systems
95 that support dynamic loading).
96
98 SANE_CONFIG_DIR
99 This environment variable specifies the list of directories that
100 may contain the configuration file. Under UNIX, the directories
101 are separated by a colon (`:'), under OS/2, they are separated
102 by a semi-colon (`;'). If this variable is not set, the config‐
103 uration file is searched in two default directories: first, the
104 current working directory (".") and then in /etc/sane.d. If the
105 value of the environment variable ends with the directory sepa‐
106 rator character, then the default directories are searched after
107 the explicitly specified directories. For example, setting
108 SANE_CONFIG_DIR to "/tmp/config:" would result in directories
109 "tmp/config", ".", and "/etc/sane.d" being searched (in this
110 order).
111 SANE_DEBUG_MUSTEK_USB
113 If the library was compiled with debug support enabled, this
114 environment variable controls the debug level for this backend.
115 Higher debug levels increase the verbosity of the output.
116 Value Description
118 0 no output
119 1 print fatal errors
120 2 print important messages
121 3 print non-fatal errors and less important messages
122 4 print all but debugging messages
123 5 print high level debugging messages
124 6 print medium level debugging messages
125 7 print low level debugging messages
126 Example: export SANE_DEBUG_MUSTEK_USB=4

140 This backend is based on the Mustek 1200ub backend from Mustek, main‐
141 tained by Tom Wang.

145 These devices have a hardware bug: Once data is written to them, they
146 can't be reset (toggle = DATA0). That means, any operation that tries
147 to reset the device will result in running into timeouts.
148 In earlier versions this backend failed when it was loaded the second
150 time in some configurations. The only choice was to replug the scanner
151 in this case. The backend uses a workaround for that bug now but it's
152 only tested on Linux. Reports for other operating systems are appreci‐
153 ated.
154 More detailed bug information is available at the Mustek backend home‐
157 page http://www.meier-geinitz.de/sane/mustek_usb-backend/.
