OK.
Yes it is running limtp and mtp-probe. But disabling libmtp and mtp-probe (
I renamed the
lib's and the mtp-probe) it make no difference.
Hmm. Did you re-boot after that ?
The safer way of disabling mtp is to comment it out of the udev configuration
and re-boot.
If it's not MTP interfering, then it seems like a Linux USB driver problem,
so this needs to be passed over to the Linux USB developers.
To be able to do that, you need to generate a usbmon trace of the failure.
See <
https://www.kernel.org/doc/Documentation/usb/usbmon.txt> for instructions
on how to do that. It's preferable to capture a text trace for just the
ColorMunki
display from plug-in to failure.
If you can mail me the trace, I'll post a question on the Linux USB mailing
list.
