[sane-devel] SANE on FreeBSD 5.3

[Micah]

I've already found that libieee1284 doesn't work on the FreeBSD 5.x 
series and consequently my parallel port scanner will not work. (it 
works as a nice paperweight though)

Before going out and buying a new scanner, I was curious if anyone has 
had any luck getting USB scanners to work under FreeBSD 5.3.

Thanks,
Micah

libieee1284 problems on FBSD 5.2.1 (was [sane-devel] canon_pp does not work)

 Hi,
 
 Since there's been two independant reports of problems with parport
 stuff on FreeBSD 5.2.1, it seems like there may be a problem with
 FBSD 5.2.1 and the libieee1284 port.  I checked up the changelog to
 see what might have caused it, and this line makes me suspicious:
 
 ---
 The puc(4) PCI Universal Communications driver now supports connecting
 parallel ports to the ppc(4) driver.
 ---
 (http://www.freebsd.org/releases/5.2.1R/relnotes-i386.html)
 
 It's quite possible that something to do with that is breaking the
 direct access to the parallel port through /dev/io which libieee1284
 performs.  Unfortunately I don't have a FBSD machine handy to test this
 theory.. has anyone out there had any success in getting libieee1284
 access on FBSD 5.2.1 working?
 
 Cheers,

Hi,

The puc driver is supposed to support dumb parallel PCI interface 
cards.  I tried enabling it in the kernel (even though my parport is 
onboard), no difference.  Also, I'm not sure how new this is, but FBSD 
5.2.1 has a /dev/ppi0, which is supposed to be for ieee1284 device 
access.  Perhaps libieee1284 needs to try this instead of /dev/io?

I'm still working on this intermittently

[sane-devel] Problems with plustek_pp in FreeBSD

[Micah]

I'm not sure if it's a system config, porting, backend or libieee1284 
problem.  I'm trying to get a parport plustek opticpro 4800p working in 
FreeBSD 5.2.1-Release.  I have sane-backends 1.0.14 with libieee1284 
0.2.8 installed.

When I do a scanimage -L, I get the no scanners were identified 
msg.  I've attached the debugging output from it.  By the looks of the 
messages it seems to open the parport just fine using libieee, but dies 
during negotiation (after [plustek_pp] We're using libIEEE1284 I/O). 
Digging into the libieee code, the only way to get the Failed at event 
2 message is if it times out during a wait_status call in default.c.

I've looked at this off and on for several days and just don't have any 
more ideas left.

Thanks,
Micah
