Hi Martin,
- add a variation of uftdi that attaches on single interfaces (Wolfgang, can you share your code, even if it does not work with -current?), and either always use this variant, or use this variant on chips matched by above mentioned quirks table.
See attached. The only other change required is in files.usb, where I had to change the "attach uftdi at usbdevif" to "attach uftdi at usbifif". With these changes I was able to attach uftdi by specifying an interface.
- make ugen be able to attach to single/specific interfaces as well (off hand I'm not sure this would need code changes, but again, Wolfgang, could you make your patches available?)
Sorry, looks like I lost any changes I made to ugen.c :-( Ciao, Wolfgang -- wolfg...@solfrank.net Wolfgang Solfrank
