Description of problem: when I use the kernel-2.6.38.7-30.fc15.i686, I could use my usb modem with the command 'modprobe usbserial'. but after I update the kernel-2.6.40-4.fc15.i686. I no longer can use the modemku. Version-Release number of selected component (if applicable): Name : kernel Arch : i686 Version : 2.6.40 Release : 4.fc15 Size : 83 M Repo : installed From repo : updates Summary : The Linux kernel URL : http://www.kernel.org/ License : GPLv2 Description : The kernel package contains the Linux kernel (vmlinuz), the core : of any Linux operating system. The kernel handles the basic : functions of the operating system: memory allocation, process : allocation, device input and output, etc. Steps to Reproduce: 1.run terminal 2.as root, run command 'modprobe usbserial vendor=0x19d2 product=0xffdd' 3.the modem was not detected.
it was changed to be built-in, so that it can be used to debug early boot. You should be able to add to the boot command line usbserial.vendor=0x19d2 usbserial.product=0xffdd and it will do the same thing. The correct fix would be to have the ID added to usbserial itself.

Actually before the command 'modprobe usbserial', I run the command 'eject' first.

With these steps I was able to use my modem, but there is another effect that is, the desktop hangs..

I met the same issue. When I plug-in my USB modem, the whole system hangs for some seconds.
The built-in change was dropped in newer F15 kernels. Are these issues still seen on 2.6.40.6?

I think modularization scheme of the kernel should be kept consistent in a released Fedora version. And will usbserial be built in or modularized in Fedora 16?
