Title:
HP Scanject 2100c not working on USB 3 root hub
Status in sane-backends package in Ubuntu:
Invalid
Bug description:
I have a HP Scanject 2100c which uses the Sane plustek backend for
comms. My PC only has a USB 3 root hub, when the device is connected,
either directly or via an external USB 2 hub, it does not work.
In general (although not always), 'scanimage -L' will detect the
scanner ok:
device `plustek:libusb:001:012' is a Hewlett-Packard Scanjet 2100c
flatbed scanner
however there is always about a 30s delay before the shell prompt is
returned. Scanning always fails however, using the suggested method on
the sane HOW-TO page:
scanimage -vvv -format pnm >outfile.pnm
Calling sane_exit
is the usual response. By enabling debug on the plustek backend, the
response I normally get results in the following:
[plustek] Vendor ID=0x03F0, Product ID=0x0505
[plustek] usbio_DetectLM983x
[plustek] * could not read version register!
[plustek] open failed: -1
[plustek] sane_get_devices (0x7fff0686dbc8, 0)
In an effort to try and diagnose this, I've build the latest SANE
backends from scratch and tried out the latest libusb none of which
has resolved the issue. My original kernel was a 3.5.x, I pushed it up
to 3.8.0-30 this also made no difference.
My guess based on what I've seen is that this is related to the USB 3
hub. The HP Scanjet worked ok on my old Linux box (a 2.6.27 kernel
with USB 2 hub). The key difference (aside from this being a 64 bit
flavour of Linux) is the USB.
