Issue with RS232 <-> USB adaptor (FC15)

[f8arr <f8arr@f8arr.org>]

Hello Hams !

Apologies for the bandwich, but perhaps someone has allready faced it ...


Here is the case :
In order to have a TX port on WSJT I use /dev/ttyUSB0 from prolific pl2303.
At boot, the serial comes up to TX.
On messages I have only this message :

Jun 13 17:00:08 f8arr2-station kernel: [ 3574.706035] usb 3-1: new full 
speed USB device using uhci_hcd and address 8

Jun 13 17:00:08 f8arr2-station mtp-probe: bus: 3, device: 8 was not an 
MTP device

Of course, If I run WSJT it can't commute the TX with an error message 
"Can't connect to /dev/ttyUSB0"

My user is on the "dialout" and "uucp" group.

I tried exactly the same manipulation with my only real RS232 port and 
it works like a charm.. (but dedicated to an other action).
Of course, same configuration was ok under my ubuntu 10.04. but I 
switched to Fedora 15...

If someone had a idea.. it would be great. My freind google didn't came 
with something looking good...
