LinuxKPI USB and wireless - do you have unsupported USB wifi dongles?

Hi,

over the last years I have on and off worked on an updated LinuxKPI USB
support.

Having managed to get a blocker out of the way I beleive (still need to
do gcc univeser builds for the very specific compiler options) I'll try
to extract the changes from my branch so some of the USB people can help
polishing this.  The main problem is to disconnect the LinuxKPI USB
structure fields from the native USB structures as otherwise we'd start
pulling halve of LinuxKPI into the native USB stack, which is a no-go.

I am at least aware of disconnect/detach panics I still had when I last
worked on this earlier this year.

In order to sort some of this and given I just had one box of USB dongles
in my hands I started to catalog some here:

(note: I am not adding old natively supported ones to that page anymore)


If you happen to have some modern unsupported USB Wireless dongles lying
around please let me know the details (if the chipset is not on list yet)
as I am looking to extend my stock for the various chipsets to be able to
test them.  Probably best to drop me a private email.

Lots of health,
/bz
