I believe that kernel > is enough (the problem is in the kernel stage, not in mounting or any > other user-level stage). I am using 4.5 RELEASE, which is not that old... As Brooks has said: there can be problems with running a newer kernel with an older world (userland). I don't know if USB will be affected, but it's possible, as you will be using an older usbd. > I'll see what I can do :) Some notes on this: * See LINT for the various options that can be set. * Setting "options USB_DEBUG" compiles debugging code into the kernel, but does not enable it. To enable it, you have to write a C program that calls the USB_SETDEBUG ioctl() (see sys/dev/usb/usb.c). * You could try setting "options UMASS_DEBUG", as this might give you enough information. Note that this option, unlike USB_DEBUG, both compiles in debug code *AND* enables it. On a side note, are you using the uhci or ohci device? I'm using uhci without any problems, and I've heard that the ohci driver isn't as good as the uhci one. -- Darryl Okahata darrylo@soco.agilent.com DISCLAIMER: this message is the author's personal opinion and does not constitute the support, opinion, or policy of Agilent Technologies, or of the little green men that have been following him all day.
