I have RB2011UiAS-2HnD device and meet the following issue. Router determine my Prolific PL2303 USB-Serial converter as usb2, but it doesn't work properly. The first problem - device is been periodically rebooted by watchdog timer. It happens only when Prolific converter is inserted. The second problem - serial console via this converter actually doesn't work. I was able to get console invitation sometimes, but couldn't enter any characters after that. I tried to use different terminal emulators (putty, minicom), but got the same result. Please help!
