Obtaining the ti_3410.fw file needed by ti_usb_3410_5052
Debian (and perhaps other Linux distros) do not package ti_3410.fw (no, not even in lfirmware-linux-nonfree). The following bash script will use git to obtain just the one file from kernel.org and move it to where "modprobe ti_usb_3410_5052" will find it:
#!/bin/bash sudo apt-get install git git clone -n git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git --depth 1 cd linux-firmware git checkout HEAD ti_3410.fw sudo cp -p ti_3410.fw /lib/firmware
The script is tested on Debian with 3.1.0 kernel and will need to be modified if your system uses RPM and/or does not follow the standard filesystem hierarchy.
Known Issues
Warning at arch/x86/kernel/apic/ipi.c
WARNING: at [...] linux-yocto-3.2.18+git1+5b4c9dc78b5ae607173cc3ddab9bce1b5f78129b_1+76dc683eccc46804729a76b9d2fd425ba540a483-r1/linux/arch/x86/kernel/apic/ipi.c:109 default_send_IPI_mask_logical+0xa4/0xe0() Hardware name: Fish River Island II empty IPI mask Modules linked in: Pid: 1, comm: swapper/0 Not tainted 3.2.18-yocto-standard #1 Call Trace: [<c103b8d3>] warn_slowpath_common+0x73/0xa0 [<c1018234>] ? default_send_IPI_mask_logical+0xa4/0xe0 ...
This appears to be a known issue with how IPIs are handled within the generic SMP infrastructure. A fix is being discussed on LKML, but the warning appears to be benign.
