Hi
Please could you help me,
I have a Mecer USB to RS232 converter that the os detects but does not
work, the led does not come on and minicom using /dev/ttyUSB0 does
return any display / input when i plug in into the admin port on my
router device..

The kernel detects is and /var/log/messages reports

Jan  8 17:30:49 greg kernel: ohci_hcd 0000:00:13.0: wakeup
Jan  8 17:30:49 greg kernel: usb 1-3: new full speed USB device using

Jan  8 17:30:49 greg kernel: usb 1-3: pl2303 converter now attached to ttyUSB0
