ok, i have tried to comment out calls sanei_usb_claim_interface and sanei_usb_release_interface with patch below
but it didnt help, device usb reinit still occurs in dmesg (as in my first post) any other suggestions or ides? thanks for your patience patch: diff -r -u sane-backends-1.0.20-orig/backend/hpljm1005.c sane-backends-1.0.20/backend/hpljm1005.c --- sane-backends-1.0.20-orig/backend/hpljm1005.c 2009-03-20 15:41:47.000000000 +0100 +++ sane-backends-1.0.20/backend/hpljm1005.c 2010-04-07 17:38:15.000000000 +0200 @@ -526,15 +526,19 @@ } /* Claim the first interface */ + /* ret = sanei_usb_claim_interface (dev->dn, 0); if (ret != SANE_STATUS_GOOD) { sanei_usb_close (dev->dn); + */ /* if we cannot claim the interface, this is because someone else is using it */ + /* DBG(1,"Unable to claim scanner interface on device %s\n",name); return SANE_STATUS_DEVICE_BUSY; } + */ #ifdef HAVE_SANEI_USB_SET_TIMEOUT sanei_usb_set_timeout (30000); /* 30s timeout */ #endif @@ -557,7 +561,7 @@ do_cancel(dev); } - sanei_usb_release_interface (dev->dn, 0); +// sanei_usb_release_interface (dev->dn, 0); sanei_usb_close (dev->dn); } > ------------ P?vodn? zpr?va ------------ > Od: m. allan noah <kitno455 at gmail.com> > P?edm?t: Re: [sane-devel] scaner on HP LaserJet M1005 MFP > Datum: 07.4.2010 16:51:00 > ---------------------------------------- > Scanimage itself does not send any usb packets, this is the domain of > the backend.
