Description Alex Kanavin 2006-11-23 09:35:36 EST
Kudzu fails to find the device file for USB ACM modems, and as a result,
system-config-network doesn't find these modems either. I believe the fix is as
simple as adding

__getSysfsDevice((struct device *)t,".","tty:",0);
right next to
__getSysfsDevice((struct device *)t,".","net:",0);
in getUsbDevice() in usb.c

Have you tested that change? (I don't have that hardware.)
Comment 2 Alex Kanavin 2006-11-28 09:29:10 EST
Yes. Before the change:
>>> kudzu.probe(kudzu.CLASS_MODEM,kudzu.BUS_UNSPEC,kudzu.PROBE_ALL)
[Desc:           Nokia Nokia 6680
Driver:         cdc-acm
Device:         None
]

After the change:
>>> kudzu.probe(kudzu.CLASS_MODEM,kudzu.BUS_UNSPEC,kudzu.PROBE_ALL)
[Desc:           Nokia Nokia 6680
Driver:         cdc-acm
Device:         ttyACM0
]
Comment 3 Bill Nottingham 2006-11-28 12:05:59 EST
You wouldn't happen to have any USB-serial converters (ttyUSBX) and notice if
this works for them? :)

Moving the call to after __getNetworkAddr - otherwise if someone does something
patently silly (names a network device ttyACMX), we'll get bogus data.

Will be in 1.2.62-1, might be in a future FC6 update.
Comment 4 Alex Kanavin 2006-12-21 13:35:25 EST
No I don't :( Looks like all modern Nokia have switched to the USB ACM kind of
interface, and I don't have any other suitable hardware.
