            But :
    - keyboard has to be plugged on an openprom compatible USB card ;
    - OpenPROM has to support USB keybord (and I'm not sure that
    OpenPROM 3.xx supports this kind of keyboard...) ;
    - your adapter has to be compatible with your PCI bus (2.2 or 2.3
    for Blade 2k, maybe only 2.1 or 2.2 for your U5) ;
    - you have to install a linux supported USB adapter.

            Your keyboard led flashes without any USB communication
    between U5 and keyboard. It only indicates it is powered and ready
    even there is no possible communication.

Oh dear, I didn't mean use a USB keyboard on a Sun U10 -- I just used simple things like flash drives. I would severely doubt that a U10 would "just work" for the reasons mentioned above.

The U5 does boot normally without the USB card. I want to use USB for a flash drive. The keyboard is a standard Sun type and is plugged into the normal keyboard connector.

The StarTech instructions say only PCI compatible (3.3/5V) and that the card is Linux compatible. I will try the card in a PC. I am sure the card is installed correctly. I tried it before with a previous version of Debian with the same result. I have a SCSI card that came from a Sun server that maybe can be used to test the PCI bus.

I doubt the OpenBoot monitor knows anything about USB but if this was the problem it would not have worked in Patrick Baggett's U10 either. I think OpenBoot would ignore the card if it didn't know what to do with it. Under Solaris one had to do a boot -r to get OpenBoot to recognize newly added hardware. Since Stop-a doesn't do anything I can't have OpenBoot probe the PCI bus.

Best regards,
