This is a report/update on a WORKING item that has been working for a
while. I was recently asked if the dlink dsb 560 usb modem works with the
ACM driver. (I had reported it as working on one of the compatibility
lists).It seems that there was disagreement somewhere on if it works or not...
and since today I got some more questions about it, here is all the relevant info on
my configuration hopefully it may
help.
Here is what I sent to one of the requests:
uname -a: Linux teddyr 2.4.19 #5 Sat Oct 12 05:25:05 PDT 2002 i686 unknown
Distro: RH73 + many RPM updates from up2date + recompiled 2.4.19.
hotplug version (installed as rpm): hotplug-2002_04_01-3
The modems device IDs are: vend/prod 0x7b8/0xf101
Minicom version (installed from RPM): minicom-2.00.0-3
Modem FCC ID: MQ4UFM560
I did have to manually create the ACM nodes in /dev
mknod /dev/ttyACM0 c 166 0
mknod /dev/ttyACM1 c 166 1
Minicom and other dialers did not like them in the currently
recommended locations. had something to do with the lock file names.....
{symptom: returns instead of opening the device.. no error...does nothing}
I am using uhci driver. {edited /etc/modules.conf to have
alias usb-controller uhci}
--- In minicom (using device /dev/ttyACM0):
AT S7=45 S0=0 L1 V1 X4 &c1 E1 Q0
OK
ati
USB V.90 56K FAX MODEM V2.01
OK
---
I am then able to dial into another to a linux box via "atdt {phone
number}" ..
now for the nitty-gritty.... :-)
--- on device connect, syslog shows:
