Just out of curiosity, what items are you trying to plug into the card?
Card readers need to have the card inserted to be seen, the device won't show up otherwise.
Which card is it? It couldn't by any chance be for USB 2.0 could it? I know they are supposed to be backwards compatible but not all are suitable for older machines. I once bought a 2.0 USB card and installed it into my 9600 only to spend the next several hours trying to bring my mac back to life. In the fine print on the box it said the card was only compatible with factory G4 macs, thank you very much.
This from Apple:
"Important: Mac OS versions 9.1 and later include a later version of this software. Installing USB Adapter Card Support 1.4.1 over Mac OS 9.1, 9.2 or later could result in the USB adapter card not working.
Important: This software supports only USB cards that comply with the Open Host Controller Interface (OHCI) specification and may not work with every USB adapter card. Contact the manufacturer of your USB adapter card if necessary to verify that your card is OHCI-compliant and supported by this software. "
I'm also thinking if you tried to install the 1.4.1 you may have to do a reinstall of 9.1 to get back whatever might have been screwed up in the attempt?
Jennie, in the other thread you said the card reader had to be powered up to be seen by the system? My Lexar is connected to a hub which is externally powered so technically it has power although it doesn't get the green light until the system starts to load , but before the desktop appears. You might want to try it with an externally powered hub. Also, as I said in the other thread, the reader needed the mass storage support extension to work.
