01:57 <DocScrutinizer05> (sorry I can't find a stable link to this, livelogs will point to something else in 22h)

06:42 <how900> isn't it part of vdev implementation to bind devices statically? Wouldn't that work?

06:42 <DocScrutinizer05> I thought it should

06:43 <DocScrutinizer05> however paul just told me that kernel is already doing this

06:44 <DocScrutinizer05> [2016-10-14 Fri 08:24:01] <PaulFertser> DocScrutinizer05: the thing is, udev doesn't really probe for devices. If you have a hid keyboard driver already loaded (for real external keyboard) and the modem suddenly changes into being a keyboard too, the kernel will bind the driver right away, without udev's help.

06:44 <DocScrutinizer05> [2016-10-14 Fri 08:24:30] <DocScrutinizer05> hmmm

06:44 <DocScrutinizer05> [2016-10-14 Fri 08:24:31] <PaulFertser> DocScrutinizer05: so that's a major requirement you'll have to pass to your kernel hackers. It's not trivial and not out of the box.

06:44 <DocScrutinizer05> [2016-10-14 Fri 08:26:18] <DocScrutinizer05> I thought there's a 2 layer setup: HID/whatever *on top* of a generic USB driver that only handles enum and physical data transfer

06:44 <DocScrutinizer05> [2016-10-14 Fri 08:26:41] <DocScrutinizer05> like, musb-hdrc ;-)

06:44 <DocScrutinizer05> [2016-10-14 Fri 08:27:24] <PaulFertser> Yes, there's a kernel usb host controller driver that does enum etc. And usb devices drivers that are in-kernel too. Can be bound without udev.

06:44 <DocScrutinizer05> [2016-10-14 Fri 08:29:39] <DocScrutinizer05> so we need to keep the usb driver (musb-hdrc, ehci, ohci, uhci (?) whatever) but teach whom? kernel? to not bind a device driver on top of that automatically for this one USB port?

06:44 <DocScrutinizer05> [2016-10-14 Fri 08:31:24] <PaulFertser> Yes, that needs to be a new kernel-level option to limit the driver binding for a particular USB port. Not sure if it needs to be HCI-specific or can be implemented in a more generic way to work for any HCI type.
