Regarding pcibios, I'm sorry I should have worded that differently. When I said I don't have a pcibios device to disable, I meant to say: when I tried to disable pcibios it said I didn't have a device called "pcibios0." I tried this using the boot-up config (config -c at the boot prompt). Is this the same method you would use for disabling pcibios? I was trying out some different BIOS settings to see if I can make anything change, and one time I rebooted I received a different error message when trying to attach the scanner: uhci_idone: error, addr=0, endpt=0x00, status 0x440000<CRCTO,STALLED> usb_new_device: set address 3 failed uhub_explore: usb_new_device failed, error=SET_ADDR_FAILED uhub0: device problem, disabling port 2 After rebooting again numerous times, it seems this happens randomly and had nothing to do with my BIOS settings. Strange... Are you aware of a way to better debug what's going on? Thanks To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
