   @wardog -- just a keyboard and mouse and it's all the Intel USB ports except for the socket on the board next to the power switch. There must be something special about that one.
@Xalter -- that's the clearest explanation yet. I don't need to reset the BIOS to factory defaults because I never change anything there but I tried that anyway . It requires a CMOS reset to get the Intel ports working again. So it's not the hardware itself. At this point it *seems* to be a combination of GRUB setting something it shouldn't and ASRock UEFI letting it do something it shouldn't. Thank you. You've been very helpful.

	What USB devices do you have plugged in? Where plugged into? USB 2.0 and or 3.0 devices acting this way? Which ones?

	Happy to try and help As I said in my last post, there are more functions available in the UEFI than are present in the UI. Many of these features are only accessible by the OS/bootloader and are not alterable by the user. All kinds of things are determined by the UEFI and many of these settings could damage the system if the user were able to access them and alter them. The issue in your case seems to be stemming from the intel USB controller that is built into the chipset. As it is chipset based it is far more intricately connected to the UEFI than the Asmedia controller which has its own separate IC. It has been a long time since I delved into the inner workings of the BIOS but if I had to guess, GRUB may be trying to alter a setting related to bootable USB devices. This change is obviously not working correctly with ASRock's UEFI, possibly due to outdated coding in the GRUB system or because compatibility for your board is not properly implemented. Once you clear CMOS after an update the system functions as it should until another update is required. This is a good thing as it means the issue is likely external, stemming from something GRUB is changing. It should be easy to test if it is GRUB causing the issue by setting a hidden UEFI flag incorrectly. Next time you perform an update and the issue occurs (it may not if the update includes a fix for the issue) try resetting to factory defaults within your UEFI. If this works then the problem is likely a setting you have missed as it will reset all user alterable values. If it does not work but clear CMOS does then you know for certain the GRUB is altering something you cannot access. Clear CMOS resets all data including hidden registers and variables. This is the reason both exist and the further battery removal method will additionally reset the Real Time Clock or RTC as it is usually referred to. If this is the case then your best bet is posting your issue on your distro's user forums and seeing if anyone there can help you. You can try Tech Support here directly and they may be able to help you but bare in mind they are not obligated to do so given the issue stems from an unsupported OS. Generally though ASRock's tech support is very helpful and eager to resolve user issues whenever they can. I hope this helps clarify how intricately connected the OS, bootloaders and UEFI are.

	Thanks for that reply. Really, I mean it. It's not so much as Linux as GRUB which gets updated. But here's the thing, even if GRUB is doing something wrong, which it may be, why can't I fix it even inside the BIOS config? And why does it only affect the Intel USB hub and not he ASMedia one? Or more generally, why is only USB effected? This is the cause of the slow boot BTW. The ports are there but they never respond.

	Lacking the understanding needed to help I saw no point in posting arbitrary non helpful advice. I am not familiar with the intricacies of how the linux kernl and boot loader operate and had nothing of use to offer. In your situation I would try and rule out hardware being the issue by doing as I stated, install windows and see if your ports fail there too. If that is the case then your particular board may have a defect or BIOS issue in which case an BIOS update or RMA would be warranted. Given the issue arises only when you perform an update it is fairly clear that Linux is making a change to the UEFI that is causing this problem. It may be enabling or disabling legacy USB support for example or any number of inaccessible, hidden controls within the UEFI that can only be set by the OS. I think the misunderstanding here is stemming from the fact that you were not aware of how much the OS interacts with the UEFI. We understand what you are saying and are trying to provide info as to what we *think* may be the issue. We sadly do not have any linux gurus here, or at least none that post regularly. You have to understand that this is not tech support, it is a support forum that is largely responded to by the community and on rare occasion a representative from ASRock's Tech department when there is a major update or common problem that they feel needs to be addressed, like the non-Z overclocking and windows 10 issues recently. This means that the advice shared is restricted to the knowledge base of the community. For dedicated Tech Support you should use the official support page to send a support request. The forums are a supplementary service that allows users to help each other out with common issues or non manufacturer based faults. Even the moderators here are community members, we are not in the employ of ASRock. Given your issue is regarding how the OS is changing settings in the UEFI, Tech Support may well be able to help you as it is UEFI related. I can't say for certain but it is worth a shot.

	Thank you for responding. I'm not trying to insult the moderators. It's just that they (including you) are missing the point. It's not about Linux vs whatever. It works great when first installed. No issues at all. It's just that after any update to the kernel all the USB ports are dead. This requires a reset of the motherboard to factory defaults to reactivate them. Other OS's e.g. Windows, OSX, do not update the boot partition with the regularity that Linux does. There is no way a bootloader update should cause my USB ports to stop working without a fault of some kind. This is a defect and if done by design, a design flaw. I'm sorry if you don't like to hear that. [edit] Just saw your edit. The only people who tried to help me were the noobs. You guys all blew me off. Edited by jglynn43 - 03 Jan 2016 at 5:42pm

	I am sorry but I see no fanboism here. The simple fact is that you are using an unsupported OS that for whatever reason is conflicting with your hardware and causing an issue. It is not a hardware fault, if it were we would be seeing numerous other posts complaining about similar behavior in Windows. Linux is a crowd developed OS and does not offer the same degree of hardware compatibility as Windows. I can understand your frustration and desire to switch brands given the product you purchased is not living up to your expectations, that is fair enough but to say it is badly designed or defective is unfounded and inaccurate. Its like buying a car you plan to convert to LPG only to discover that that particular model is not compatible with the modification, it is hardly the manufacturers fault that a third party has not made a conversion kit for that particular model yet. Just because UEFI is supported by all distros does not mean there are no bugs. If you are an avid linux user you should already be well aware of this fact. Linux is not an install and forget OS and while it is a fantastic piece of software it is not without it's faults. Before you fly off the handle and start accusing moderators of being fanbois try contacting tech support directly with your issue and see if they are able to help you. Even though linux is not a supported OS there may well be something that can be done, be it reverting to a previous BIOS version or some workaround. [edit] The OS effects the UEFI so yes, it can be OS related. Unlike the old simple BIOS system the UEFI is designed to interact with the OS. Now it may not be the OS but the only way to rule it out is to install Windows and check if the problem persists. Please cease the inflammatory comments, the people posting here have been trying to help you and do not deserve to be insulted for taking the time to reply to you.

	I hate to respond to my own post post but wow did you completely miss the whole point of this thread. The USB ports stop working. Completely. Even before the OS is loaded. So how is that related to the OS smartguy?

	Almost no one says they support Linux. So what. This is hardware. Yes, UEFI is supported in all distros that I know of. Linux is not the problem. It works great until you have to update. You just do that more often with Linux than other OS's. I suspect the other ones will have the same problem in that instance. Stop being a fanboi. This design sucks.

	Just sayin', Linux is not supported, which is the response you would get from support, sorry to say. You must know as a Linux-type user, you're on your own getting the things you use to work correctly. Zero mention of Linux in the Specifications, this and other ASRock boards are not marketed towards Linux users. Mother boards are becoming less generic, at least with Intel processors and chipsets. The new Intel 100 series chipsets do not support Windows 7 100%, you must add the USB 3.0 drivers to the Windows 7 installation package. Can you install Linux with an EFI bootloader? Disable CSM in the UEFI, or at least use the EFI Storage Option ROM? Either of these things will reduce POST time. That of course assumes Linux storage drivers can work with Intel EFI storage Option ROMs. How does Linux interface with the Intel Management Engine firmware that is part of the UEFI? If an Intel 9 series chipset (Z97) board is giving you grief with Linux, don't go to the new 100 series chipset boards, they will likely be even less cooperative. Will a different board manufacture help? IMO, no.
