xsane error : Device busy with Espon 1260 if libsane-extras is installed.

[Julien Gilles]

scanimage works fine.

scanimage -L gives :
device `plustek:libusb:002:002' is a Epson Perfection 1260/Photo USB flatbed scanner

With libsane-extras, xsane fails with "Device Busy" error.

Using SANE_DEBUG_DLL=1 SANE_DEBUG_PLUSTEK=30 xsane ends with

[plustek] usbDev_getCaps()

Without libsane-extras : the line "[dll] load: dlopen() failed
(/usr/lib/sane/libsane-hp_rts88xx.so.1: undefined symbol:
sanei_scsi_find_devices)" is not present, and xsane works fine.

In fact I do not need libsane-extras, so my solution is to not install
libsane-extras, but it should works with it.

I don't know if the problem is in xsane or in libsane-extras, I can send more traces if needed.

Does this still happen in current Dapper?

[Scott James Remnant (Canonical) (canonical-scott)]

Please test the upcoming dapper Beta release; and reopen if this still fails.

Works fine with or without libsane-extras in Dapper.
