Forgive my interfering but I'm not sure all this comes from userspace
(although the cause could be in userspace).
I had a look at the ti driver code earlier in the week and first four
messages looked to me like a failure to get the TI device into firmware
I wondered if the driver had ended up probing something with nothing
connected to it.
Either way the timeout for both install/uninstall mean that it's taking
two (elapsed) seconds longer than it should to complete the operation.
