Hi,

> Has anyone here had any experience with USB serial port adapaters?  Which 

Yes, an mct_u232. Model UC232A SN R9-200012AD0015
(made in ta�wan, of course )

I was searching a long time to make it work with the mct_u232 module, 
but it'doesn't work correctly.

I now know why : simply load the pl2303 has solved all my problems :-/

(I now understand why it doesn't work with win$ and Mac OS 9/X) :-) )

fyi :

cat /proc/bus/usb/devices give me :


P:  Vendor=0557 ProdID=2008 Rev= 0.01	# *very important*
C:* #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=100mA
I:  If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=00 Prot=00 Driver=serial

E:  Ad=02(O) Atr=02(Bulk) MxPS=  64 Ivl=0ms
E:  Ad=83(I) Atr=02(Bulk) MxPS=  64 Ivl=0ms

and � tail -f /var/log/messages give me :

tomate:/home/eric# tail -f /var/log/messages

No problem : it work's fine with gtkam or gphoto + libusb + an Olympus 
C830 (an old one, now ;-) )

btw : it works better on my ibook, than on my x86...and I don't really 
know why !! (better hardware ?)
