[irda-users] no discovery with MA620 on 2.6.3

[Thanos K. <dj...@li...>]

Hello, 

I've been watching the previous thread on MA620 dongle and wanted to 
also test it. For the history, I've been trying to get the MA620 
working since kernel 2.4, but back then the result was to get a frozen 
system every time I tried to minicom my mobile phone, so I was waiting 
for a more updated irda subsystem.

Anyway, I'm using a clean 2.6.3 on a Slackware box. The kernel is 
running SMP (Pentium 4 with HyperThreading) and preemptive. I've 
followed the same steps:

/etc/modprobe.conf is clean of any irda stuff.

# modprobe pl2303; modprobe irda;modprobe ma600-sir
# irattach /dev/ttyUSB0 -d ma600 -s
# lsmod |head

ma600_sir               2688  1
irtty_sir               6784  2
sir_dev                14524  2 ma600_sir,irtty_sir
irda                  134716  2 ma600_sir,sir_dev
pl2303                 15492  1
usbserial              25964  3 pl2303

dmesg says:

The dongle never discovers my Siemens ME45 mobile phone.
When I bring the phone close to the dongle, the receiving led of the 
dongle flashes, but it never discovers it. output from irdadump:

The baud rate is by default 9600.
The dongle works fine under Windows.
