I have several FTDI modems that work OK with Linux computers and older routers like Asus RT-N16 and TP-Link WDR4300, but nothing happens when I plug any of them into Asus RT-N18U. These modems are based on Telit (GL868-DUAL). If I plug FTDI device into usb port and leave it there then crash does not happen. Today I left it to sit idle for 24 hours without problems.

Hi, I am trying to get USB2Serial Converter (from Digitus (should be ftdi)) on ASUS WL-500gP v1 with Kamikaze 8.09 RC2 working. I installed usb stuff, and mount my usb stick to /opt and added it to /etc/opkg.conf. USB stick is recognized and working. Dec 02, 2014  Finding a Cheaper USB to Serial Chips. The CH340 series of chips do exactly what you would expect them to do: a full-speed USB device that emulates a standard serial interface, with speeds from 50bps to 2Mpbs. The chip supports 5V and 3.3V, and all the weird modem lines are supported. This chip even has an IrDA mode.

But if I run something that opens that port then crash happens soon at random. For example today I ran his: socat -d -d -d /dev/ttyUSB0,b9600,clocal=1,cs8,nonblock=1,ixoff=0,ixon=0,raw,echo=0,crtscts=1 EXEC:'/usr/bin/ssh -y -y -t -l root -I 600 127.0.0.1 /bin/bash --login',pty,setsid,ctty And soon crash happened. /dev/ttyUSB0 disappears, reinserting does not help. Removing/installing ftdi_sio module does not help either. Hmm, it seems that crash happens only when I have TWO devices connected -- FTDI and CDC ethernet dongle. BTW, CDC device does not work cleanly, sometimes it complains about kevent 12, but it still works: [ 17.519132] cdc_ether 1-1:1.0 eth3: register 'cdc_ether' at usb-ehci-platform.0-1, CDC Ethernet Device, f8:35:dd:25:fe:db [ 17.530222] usbcore: registered new interface driver cdc_ether [ 20.756135] cdc_ether 1-1:1.0 eth3: kevent 12 may have been dropped If I connect only FTDI device or only CDC device they work alone OK.

If I connect them at once, FTDI dies within few minutes. CDC device sometimes does not work unless I run usbreset and then it begins to work across several reboots. I don't know if it's a separate issue or not.
