It seems I only know enough linux to get myself in trouble.
I'm working on a couple of embedded systems (two different models) both running linux. I've been troubleshooting a modem support code that I had working with the newer one of the two. I stopped the code and tried to manually load the usbserial driver. On the newer device, when I load the usbserial driver, four devices appear in /dev/ttyUSB#.
What I did
I noted that there were actually 16 ttyUSB## devices listed all the time on the older device. They never disappear. I'm guessing [now] it is because the older kernel works differently or something. Unfortunately, I went ahead and deleted all 16 ttyUSB## devices. Now they are gone and won't come back. I don't know how to create character devices. What can I do to get those devices back?
uname -r returns
If there is some important piece of information I've left out, comment and I'll add it. Thanks in advance!
