InstallingtheKernelSources
TobuildtheTIUSBdriveryoumusthavethematchingker nelsourcesforyourkernel. 
Inparticular,youmusthavethefileusb‐serial.hforyourkernelsources.SometimesLinuxdistributionsinclude
thekernelheadersbutnotthecompletekernelsources,andusb‐serial.hismissing.However,thecomplete
kernelsourcesshouldstillbeavailableasaseparatead
d‐onpackage.
Toverifythatyouhavematchingkernelsources,run"uname‐r"togettheversionoftherunningkernel.Then
checkforthedirectory/ usr/src/linux‐<version>,/lib/modules/<version>/source,/lib/modules/<version>/build,or
/usr/src/linux‐<stripped_version>,wherestripped_versionhastheextraversioninformationremoved.Inthese
directorieslookforthefile
sinclude/linux/autoconf.h,.config,anddrivers/usb/serial/usb‐serial.h.
Ifyoudonotfindthecorrectkernelsourcedirectory,youmustfindandinstallthekernelsourcesfromyour
distributionCDsorothermedia.
