I'm working on a re-install of Win98SE and I seem to have two pieces of hardware that are finicky to install:

- Logitech cordless mouse (Cordless Access Duo)
- Agfa SnapScan Touch Scanner

When I install MouseWare for the mouse, the MouseWare detects it and lets me configure everything I need to. The only caveat is that the mouse does not update from Microsoft PS/2 Mouse (with a yellow question mark, code 10, I believe) in the device manager. I have to explicitly update the driver by selecting the appropriate INF file. I don't remember having to do this the first time I installed MouseWare. The only thing I can think of: when I installed it the first time, I had a different set. Now I am installing MouseWare for a different logitech set which is newer than the version of MouseWare I'm installing. Could this cause an adverse effect such as the one I just described?

As for the Agfa scanner, I install the software (Scanwise), and plug in the scanner, and it shows up as a flagged item (yellow question mark) in the device manager. Once I remove it from the device mgr., then the scanner is detected properly by Windows (and also detected again at first reboot, but NOT duplicated in the device mgr.) and the flag in the device manager goes away. I can't think of any reason why it might do this other than possibly buggy software.

Both of these incedents are isolated and independent from eachother. And everything works properly once this is all done - but it sure is annoying the beans out of me why it's doing this.

Does this kind of thing just happen with some manufacturers' driver software?

FYI, I've also installed other hardware (a USB hard drive and a Palm pilot) without any problems what-so-ever...so I know that it's not my internal USB hardware, chipset, bus, etc.

Try booting into safe mode and removing all instances of the two devices from device manager and then rebooting. If you have MS Intellipoint software installed remove it before the above actions. Scanners don't seem to like sharing with other devices that use the twain driver. If something else is already linked to that driver there could be a conflict. Sometimes all it takes to get past that yellow mark is to say to enable the device, or instead of re-installing, just update the driver at that point using the same driver.
