Thank you for reading this.
At first sight this may appear to be an off-topic question but it does
relate to amateur radio because without a functioning serial port I don't
have any useful amateur radio applications.
I have a USB to serial converter that worked out of the box with successive
Mandriva versions up until Mandriva 2008. Plugging the USB converter into a
USB slot used to automatically generate a /dev/ttyUSB0 device; now it
doesn't. Also, now my PCMCIA modem isn't working, no doubt, for the same
reason.
modprobe ftdi_sio, which is the module for the converter, causes the
following error messages to be displayed:
WARNING: Error inserting usbserial
(/lib/modules/2.6.22.9-laptop-1mdv/kernel/drivers/usb/serial/usbserial.ko.gz):
Unknown symbol in module, or unknown parameter (see dmesg)
FATAL: Error inserting ftdi_sio
(/lib/modules/2.6.22.9-laptop-1mdv/kernel/drivers/usb/serial/ftdi_sio.ko.gz):
Unknown symbol in module, or unknown parameter (see dmesg)
lsusb -v displays information about the converter, so it is known to the
system.
I can't see anything in dmesg that relates to either module. I have scoured
the Internet as well as posted questions to the Mandriva mailing list and
haven't found anything that might lead to the answer. Can anyone offer a
suggestion?
Regards,
Phil.
