Operating Systems Linux Ubuntu Does /dev/ttyUSB* causing my usb 3G Dongle doesn't work when plug-in Post 302505351 by Corona688 on Wednesday 16th of March 2011 06:39:13 PM

Didn't you already create a topic about this?

You might have better luck in our hardware forum, or in an Ubuntu-specific forum.

I don't know why the /dev/ttyUSB devices don't appear, but it seems more like a symptom than a cause. It may be a kernel-related problem. You might be able to get some information from dmesg, compare what you get when you boot with it plugged in with what you get when you plug it in later. Also see what lsusb tells you, it may give you more specific model numbers etc. to hunt for.

To compile this driver into the kernel, place the following lines in your kernel configuration file: device ums device uhci device ohci device usb Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): ums_load="YES" DESCRIPTION
The ums driver provides support for mice that attach to the USB port. Supported are mice with any number of buttons and mice with a wheel. The /dev/ums0 device presents the mouse as a sysmouse or mousesystems type device. See moused(8) for an explanation of these mouse types. FILES
