July 15, 201015 yr This evening I have assembled a new system to host unRAID ... a Core i3, in an H55 chipset motherboard. One of the features of the H55 chipset is that it provides 12 usb ports. I wasted a fair amount of time trying to work out why my network was unreachable - even ping localhost told me network unreachable! Eventually I did a quick search on this forum and discovered that the error was due to my usb stick not being mounted. I tried other usb ports and found that everything works fine when using other ports. I haven't done an exhaustive check on all available usb ports but I deduce that the maximum number of usb ports supported by unRAID/slackware is more than 7 but less than 12. What is the actual number supported, and can it be increased to 12 in order to prevent other people being caught out in the same way that I have been? Once I have completed the system build, and run it for a few days, I'll report my configuration in the 'Motherboards' section.

Once I have completed the system build, and run it for a few days, I'll report my configuration in the 'Motherboards' section. I've not checked if Slackware has a limit, but I do know my C2SEE BIOS has a config option for how many USB ports to enable. You might want to check your BIOS to see if the higher numbered ports are enabled at all. If they are not, it could be why Slackware did not see them.
July 15, 201015 yr It's also possible that your USB ports aren't all provided by the same chipset; for example, 8 may be via the onboard USB chip, and 4 more may be an extra chip, or the like. Are any of them USB3.0? I'm gonna guess that one of the two chipsets providing USB connectivity on your board isn't supported by the unRAID kernel, and so you only see the ones that are.
July 16, 201015 yr Author The H55 supports 12 usb ports itself - there is no other support chip. All the ports are enabled ... perhaps I should have described the symptoms more fully: The usb stick is seen, bzroot and bzimage are loaded from it, slackware boots, but fails to mount the flash drive, so that none of the configuration files can be found. Anyway, I have completed the build, moved the drives from my old machine, and all is up and running. So far, I am very pleased - the system seems to be extremely fast (subjectively ... I know that others have performed measurements on an i3 530/H55 system). It is also whisper quiet - the WD drives are the loudest aspect. I have no qualms about situating it right next to my Home Theatre system.
July 16, 201015 yr Author Okay, it was a bug in the BIOS ... just updated to the latest version, and the errant usb ports are now working fine!
