@m144 Thanks for that. OMG, how many new USB devices are there just by plugging into the dock. Yeah the ID 045e:07c6 seems about right. Though this has been added to the kernel (official and our custom build one) source code long ago.
Re-reading what you said before I feel this is a really hard one to nail down. Seems like we have the driver right in the kernel and it does come up with an IP part of the time but not always. Not really sure where to go from here. Hmmmmm
