As I want to connect a HFC-S USB ISDN adapter to my slug, I stumbled across several things:
HFC-S USB hardware:
The following table is aggregated from the hfcs-usb misdn driver
The Winbond Draytek miniVigor128 (unusable for misdn) looks like this (according to /proc/bus/usb/devices)
The current mISDN driver isn't tested on big endian machines and it won't even recognize your adapter once you plug it. I've build a bitbake file for OpenEmbedded, and posted it to the OE bugtracker you get the bitbake and endian-patches from there. It will build the needed kernel modules. The problem until today is, that you need the common kernel CAPI support.
$ grep ISDN openembedded/packages/linux/openslug-kernel-126.96.36.199/defconfig
I will try to talk the openslug guys into enabling this, so that the produced mISDN modules do work on your slug. Until then you have to build your own CAPI modules.
The next step is to get mISDNuser working. There are several issues with headerfiles, for example the bitops.h from kernel headers does include several bit operation macros on x86 but not on ARM, I don't really know why.
It loads fine on my slug (dmesg after modprobe hfcsusb debug=0):

This is on a TurboSlug (266MHz):

As you can see, ilbc and lpc10 are floating point based and not usable on a slug as long as you don't recode these codecs in a fixed point way due to the lack of a floating point unit :-)
- Is this working fully functional with a HFC-S adapter?
- Where can we get a kernel with ISDN and the HFC-S module?
