Are there vMotion incompatibilities if I am using a usb over IP solution, that cause either the vmotion to be stopped or my usb over IP solution to be hindered?
None. All the client connected USB device (USB over IP) should be reconnected to the VM after vMotion.
There are a few caveats : If you vMotion your VM to a host that has an older version of ESX (and thereby an older HW version), then some functionality might be affected.
For example: If you have a USB 3.0 device connected to a Windows 8 VM on ESX and your VM moves to an older version of ESX that does not support virtual USB 3.0 controllers ( as dictated by the HW version), then your USB device might not be usable in the guest.
