There are problems with bus mastering ISA and certain chipsets that show up
under Win 2K but not Win NT. I got myself PCI SCSI 4 years ago. "Tony" wrote in message ... HW setup: PC + Adaptec 1542CF + Adaptec 2904 Acer (now BenQ) ScanWit 2720S Filmscanner Microtek Phantom 336 Flatbed Both scanners connected to the 1542CF, film scanner first, then flatbed. then terminator. Both working flawlessly when I run with WinNT 4.0 (SP6a). Apparently there is no HW problem (?). However... running W2k SP4 I can't get them to work properly. Both devices are detected properly and I installed the latest drivers. |

Scanners and Windows 2000
Hi,
I'm having some troubles with my scanners... HW setup: PC + Adaptec 1542CF + Adaptec 2904 Acer (now BenQ) ScanWit 2720S Filmscanner Microtek Phantom 336 Flatbed Both scanners connected to the 1542CF, film scanner first, then flatbed. then terminator. Both working flawlessly when I run with WinNT 4.0 (SP6a). Apparently there is no HW problem (?). However... running W2k SP4 I can't get them to work properly. Both devices are detected properly and I installed the latest drivers. But when I try to scan anything (no matter which scanner) they start doing so, e.g. the film scanner is focussing, but after a while the procedure stops and some time later I get a timeout and the scnner isn't recognised anymore. After a power cycle the scanner regains consciousness and I can again start scanning but it hangs at the same step as before. What I've tried so far: *) Removed all TWAIN drivers *) Removed all SW that uses ASPI (surprisingly many) *) Tried about a half dozen different ASPI layers *) Tried TWAIN dll's from twain.org *) Removed one scanner (tried each) from SCSI chain And of course I have installed/uninstalled the drivers at all stages and rebooted every time. Also I made sure that when uninstalling the files really disappear (quite often there are leftovers) and that the registry is clean (?). The SCSI drivers in my system are aha154x.sys and aic78xx.sys (both from the W2k CD)I have re-installed these from the CD as well, but the files were identical and - of course - it didn't help any. And yes, I've tried Vuescan. Same story... I'm runnig out of ideas. Suggestions anyone? sigh Tony |

First, I'm no expert in this area; the following is my PERSONAL experience
with ASPI and Win2K (Folkert take note): I had similar problems writing to my CD writer using programs that require ASPI under Win2K... Win2k does not use the ASPI layer and does not (officially) support its' use, and installing it (ASPI) gives hit-or-miss results. I found that I can use the aspi driver under *certain* circumstances... under other circumstances it hangs my bus. Apparently there is some conflict with the aspi layer whatever newer protocol/transport/whatever Win2K uses... Here's some unverified info I found in another post that seemed relevant: Adaptec developed software drivers for their SCSI cards, the ASPI drivers. CD burners were initially SCSI-only devices, so other hardware and software makers could reasonably expect the ASPI drivers to be installed on any computers using their product. So rather than develop their own solutions, they took advantage of Adaptec's existing drivers. Fast forward to 2001. Microsoft produces two operating systems, Windows ME and Windows 2000, that don't support ASPI in some fashion or another. Rather than rewrite ASPI to ensure that it is stable, Adaptec made a business decision to drop ASPI and use the new built-in capabilities of Windows to instead. So they changed their SCSI card drivers and their software (ECDC) so that it doesn't need ASPI. (ECDC 4.02e runs fine on my Win2k machine without ASPI.) Now all of the software makers that hooked on to ASPI are hosed because Adaptec doesn't support it anymore under Win2k and Win ME. How is that Adaptec's fault? I've never seen Adaptec incourage other software makers to use the ASPI layer. I've never seen them push that as a standard. In fact, as we all know, they have tried to prevent anyone else from distributing it. "Tony" wrote in message ... Hi, I'm having some troubles with my scanners...

As you can see I have a PCI card in my system as well which serves
6 devices (disks, CD/DVD/ZIP drives). I have already swapped the two cables. That causes some reconfiguration to make all the disks work again (drive letters...) but the gain is zero, i.e.the scanners behave on the PCI card the same as on the ISA.

Maybe I should give a list of my ASPI trials...
1) The one that came with W2k I've checked the service packs. There is no update for these. 2) Adaptec v4.6 3) Adaptec v4.7 alpha 2 (anybody has any newer?) 4) Nero v2.0.1.45 5) LSI v1.7.1 6) ACARD (came with film scanner driver) They do not all behave the same way. Some do not generate the pop-up error message (timeout) but rather cause the program to hang. The error code also seems to vary with different ASPI layers. Nero is definitely the "best" because it doesn't even detect any scanners... BTW: scsi configurations are detected nicely with a tool called "aspi_you" I found somewhere on the internjet.

First, I'm no expert in this area; the following is my PERSONAL experience with ASPI and Win2K (Folkert take note): I had similar problems writing to my CD writer using programs that require ASPI under Win2K... Note that ASPI for Win2K has been updated at least twice in last few years. When W2K came out, you had to use the version that still worked on Win95 also. Now there have been 2 or 3 versions that are specifically for XP/W2K. They also work on 98/98SE/Me also, if one needs an update. If you are already using latest, 4.7something, disregard. Mac |

The latest drivers for the Benq do not work, I opened a ticket with Benq and
they told me to revert to the original drivers ver. 3.40 and the scanner works fine. MrC "Tony" wrote in message ... Hi, I'm having some troubles with my scanners...

Apparently there is some conflict with the aspi layer whatever newer protocol/transport/whatever Win2K uses... I really donīt know what to say upon that, because my scanner runs perfectly under Win2k with ASPI. Anyway here goes my system configuration, if it can help: Win2K SP4 Adaptec ASPI 4.60 (1021) HP ScanJet 4c scanner connected to Adaptec 1542CF ISA SCSI controller Asus P3C-LS motherboard (with embedded Adaptec AIC-7892 Ultra160 SCSI controler) 2 Plextor SCSI CD-RW drives 2 Seagate SCSI Cheetah HDs Just two notes: 1- Adaptecīs "ASPI Check" utility reports my OS as WinNT instead of Win2K. 2- The scanner does not works properly if connected to the SE segment of motherboardīs SCSI controller bus. Good luck, Rubens ------------------------------------------------------------------------------- (snip) |
